C# Language
1. Implicit Typed Local Variables
Declaring variable without specifying data-type.
E.g. var count = 1 ; instead of int count = 1;
E.g. var str = "Hello World"; instead of string str = "Hello World";
- var is not like an object or a variant type that has expensive cost.
- The compiler will set the data-type depending on what you initialize the variable.
Usage of Type Inference
- You can use it When deal with Anonymous type in LINQ.
- Declaration must include an initializer.
e.g. var test = "Hello World";
- Initializer must be an expression and not an object or collection initializer and also can not initialize it with an array.
e.g. var test = {1,2,3} ; //Gives error
- Compile time type of the initialzer expression can not be the null type.
e.g. var test = null;
- Implicity typed local variable can be initialize more than once but not with different type.
e.g. var test = 1;
test = "Hello World";
Benefits of Type Inference
- Save the typing time.
- It induces/brings on variable initialization
Limitations
- Scope is limited to local variable
2. Auto Implemented Properties
A way to declare property without code block in property accessors.
Usage of Auto Implemented Properties
- We can use it in data-accessor classes.
Note: VB 9.0 does not have auto implemented properties feature while C# 3.0 have.
- It makes property declaration more concise when there is no custom logic required in property accessors.
For example,
Suppose we have to create a class Employee with private attributes First-Name, Last-Name and ID. Now in order to access its attributes values either we can create properties or functions for each attribute.
In C# 2.0, we implement Employee class with above requirements as follows
public class Employee
{
int _id;
string _firstName;
string _lastName;
public int ID
{
get
{
return _id;
}
set
{
_id = value;
}
}
public string FirstName
{
get
{
return _firstName;
}
set
{
_firstName = value;
}
}
public string LastName
{
get
{
return _lastName;
}
set
{
_lastName = value;
}
}
}
In C# 3.0, we implement Employee class with few lines for above requirements.
public class Employee
{
public int ID
{
get;
set;
}
public string FirstName
{
set;
get;
}
public string LastName
{
get;
set;
}
}
How to create read-only property?
We can create read-only property by adding private keyword private before set.
e.g.
public class Employee
{
public int ID
{
get;
private set;
}
}
How to initialize read-only property?
public class Employee
{
public Employee(int ID)
{
this.ID = ID;
}
public int ID
{
get;
private set;
}
}
You can not create write only auto implemented properties but you can create it by traditional way.
public int ID
{
set
{
_id = value;
}
}
Benefits of Auto Implemented Properties
- Save typing time
- Increase productivity
3. Anonymous Types
A way to encapsulate a set of read-only properties into a object without defining class explicitly.
- The compiler will define a type/class automatically that represents the Anonymous Types in background.
- Anonymous types have been created with the help of "Object initializers" and implicitly typed variables.
- The Anonymous type is created with read-only properties mean you can not assign values to it after creation.
- It is strongly type.
- Mutable in VB and immutable in C#.
For example,
var product = new {Name = "C# Rocks!", Price = 3};
Automatically gets translated by the compiler to something like this:
class __Anonymous1
{
private string name;
private int price;
public string Name
{
get { return name; }
set { name = value; }
}
public int Price
{
get { return price; }
set { price = value; }
}
}
__Anonymous1 product = new __Anonymous1();
product.Name = "C# Rocks!";
product.Price = 3;
Usage of Anonymous Types
- Use anonymous types when you deal with Linq to store query results. Anonymous type can be used in "LINQ to SQL" to access some of the fields from a whole set of fields.
Limitations of Anonymous Types
- The scope of Anonymous type is limited to the method in which it defines.
- It can not be used in method parameters or return values, class level (global) variables, properties.
4. Extension Methods
A way to extend an existing type
For example,
public static class StringExntensionMethods
{
public static void AlertMessageBox(this string str)
{
MessageBox.Show(str);
}
}
string str = "Extesion Method Example";
str.AlertMessageBox();
Benefits of Extension Methods
- To extend an existing type.
- To specify validation on value of an existing type instance.
5. Object and Collection Initializers
A way to initialize accessible members of a class at object creation time without invoking constructor explicitly.
For example,
class Employee
{
// Auto-implemented properties
public int Age { get; set; }
public string Name { get; set; }
}
// Object initializer
Employee obj = new Employee {Age = 24, Name = "Test"};
public class CoOrdinate
{
public int x ;
public int y;
}
Now we can create and initialize the object via this.
var myCoOrd = new CoOrdinate{ x = 0, y= 0} ;
The above code can also be replaced by creating constructor with arguments Age and Name. Then what is the benefit of Object Initializers? The benefit here is that the arguments order and the number of arguments.
- Collection initializers allow to specify one or more element initializers when you create an object of collection class that implements IEnumerable.(i.e. Element initializers can be a simple value, an expression or an object initializers.)
In C# 2.0, we create collection and add elements in collection.
For example,
Listanimals = new List (); animals.Add("monkey"); animals.Add("donkey"); animals.Add("cow"); animals.Add("dog"); animals.Add("cat");
In C# 3.0, the above code will be replaced by collection initializers features in C# 3.0
List
"monkey", "donkey", "cow", "dog", "cat" } ;
//Element initializers as a simple value
List
//Element initializers as a Object initializers
List
Benefits of Object and Collection Initializer
- The benefit of object initializers is that the arguments order and the number of arguments.
6. Lambda Expressions
It is a substitution for anonymous method – declaring method inline.
For example,
1) Traditional way of assigning method to delegate
delegate bool SomeDelegate(int i);
public void SomeMethod()
{
SomeDelegate sd = new SomeDelegate(OtherMethod);
}
private bool OtherMethod(int i)
{
return i > 2;
}
2) Replacing traditional way of declaring method and then assign it to delegate by declaring method inline via anonymous method.
delegate bool SomeDelegate(int i);
private void SomeMethod()
{
SomeDelegate sd = delegate(int i){return i > 2;}
}
3) Replacing anonymous method using Lambda Expression
delegate bool SomeDelegate(int i);
private void SomeMethod()
{
SomeDelegate sd = (int i) => { return i > 2;}
}
Benefits of Lambda Expressions
- Save typing time via minimal syntax - write inline code block where delegates are expected. No need to specify return types and name explicitly.
- It provides support for expression tree.
Usage of Lambda Expressions
- Replacement of Anonymous Methods.
- It can be also be used for filtering, sorting, iterating in generic collection and LINQ.
To make an instance of an object globally available and guarantee that only one instance of the class
Singleton provides a global,
Making the class create a single instance of itself.
Making the class create a single instance of itself.
public class SampleSingleton
{ //SingleTon
private static volatile SampleSingleton _instance;
private static object syncRoot = new Object();
public static SampleSingleton Instance
{
get
{
if (_instance == null)
{
lock (syncRoot)
{
if (_instance == null)
{
_instance = new SampleSingleton();
}
}
}
return _instance;
}
}
public string getDisplay()
{
return "SingleTon";
}
}
///Access singleton
SampleSingleton.Instance.getDisplay();

Issues related to the deployment of data access application
Here are Some of the basic issues related to the deployment
of the data access applications.
1)Can we suppose the required database exists at the target location?
2)If the database does exist then how can we get the connection string of it? Should we get it at the installation time? Or at the first run?
3)If the database does not exist then how it can be created? Is it the responsibility of human installing our application? Or the application should create it at the time of installation?
4)If the database is to be created by the application installation, then how does the installation setup know where (on which machine) to create the database? And what user name and password the setup should use to create the database?
5)Once, the database is created or its connection string is found at the setup time, then how to store the connection string for later use (regular execution)?
6)What if the database address (connection string) is changed during the application life cycle then what should be the application behavior? How can the application be aware of the new connection string?
7)If the database schema is hard-coded in the code (like table and field names) and the DB schema is changed (table/field name or data type is changed or new field/table added or some fields/tables deleted) because of any reason, then how to fix this problem?

Dropdown Problem with Firefox
Basically, what Firefox did was keep the
right div floating to the right, but underneath the middle div. This
wasn’t what I wanted at all, and after about half an hour of fiddling
with the code I managed to fix it.
The Solution
All I did was cut the right div out of the code and placed it before
the middle div. It still had the same style attributes, all that was
needed was a quick swap. And hey presto! It worked!
The CSS
#left {float: left;}
#middle {float: left;}
#right {float: right;}improving image quality
As you can see, the image is smaller again, but the quality has
improved. First I have to remove part of the coding which makes that
icon and link to Picasa. In order to change the image size, this time I
don't have the width and height parameters showing in the code. Yeah.
But what I can do is turn the s400 number, which does show in there,
into s800.
So from this:
We change to this:

Sometimes we need larger control over our program. In WPF the
framework hide the Main method from us (altough it can be found in the
obj/debug(or release) directory in the App.g.cs file). Fortunately it's
possible to overwrite this method:
Step 1: open the Visual Studio with the WPF project
Step 2: in Solution Explorer right click on the App.xaml select Properties and set the Build Action to Page (so we can define resources here, as normal)
Step3: add a new class file to the project:

App app = new App(); //this is the default classname and not our application's
name
app.InitializeComponent();
app.Run();
}

WPF Combobox Databind to a Dataset
Often there is a question on "how to bind ComboBox to a
Dataset?". A short and simple answer, You cannot. The more specific
answer is, you bind to a DataTable and not a DataSet.
There are two ways to accomplish this,
1. Setting the Path of the ItemsSource in XAML and then setting the DataSet as the DataContext.

Code behind,
2. Setting the ItemsSource of the ComboBox to the DataTable from the DataSet.

Menu Control in WPF
In this article i will be exploring the different aspects of
Menu Control in WPF. I assume that the audience are familier with WPF
and Declarative programming using XAML. In brief WPF is the next
generation of User Interface designing. XAML helps in making clear
separation between Design and code behing logic for design. Explaining
about these is out of scope of this article, i go ahead with the
assumption that you know basics of XAML and WPF.
Menus has been an integral part of any Windows based application. In WPF there are two classes that are used for making Menu; Menu and MenuItem. A Menu is a collection of one or more MenuItem. Each MenuItem can have a Command associated with it. A MenuItem again may further have MenuItem associated with it to make submenus. In this article i will show how to work with menus.
Lets start by looking how to create a Menu (XAML Code).
This tag creates a Menu Control. Now lets look at some major properties of Menu Control.
Name --> Defines the name of the menu.
Height --> Defines the Height of the menu
Width --> Defines the width of the menu
Margin --> Defines the position of the menu
Background--> Defines backcolor of the menu
HorizontalAlignment --> Defines the horizontal alignment of the menu inside the parent control.
HorizontalContentAlignment --> Defines the horizontal alignment for the menu content.
VerticalAlignment --> Defines the vertical alignment of the menu inside the parent control.
VerticalContentAlignment --> Defines the content alignment for the menu content.
ToolTip --> defines the tooltip for the menu.
Now that we have seen the major properties its time to see them in action. A Menu tag with all its properties set may look like:
In this sample we have set properties of the menu in XAML, but this is not the only way of doing so. Properties of a menu can be set in three different ways:
In XAML manually as done above
Using Property Window
using codebeind in C# at runtime.
Now that our menu control is ready lets add some Menu items to it.
As said earlier MenuItem tag is used to add menu item to a menu.
< MenuItem Header="_File"/>
Here we create a Menu Item with name as File.
A menu item can in turn have other menu items within it as sub menus. Now lest add some more menu items to our File menu.
Here we have added 4 menu items and a separator to the File Menu
A separator is used to categorize similer menu items. It is added with < Separator/> tag.
We can also add sub menu items to sub menus.
The xaml will look like
Now lets add a tool tip to our menu item.
Now lets look at adding and event handler to menu item.
The Click event is used to associate an event handler to the menu item.
And in the code behind
Menus has been an integral part of any Windows based application. In WPF there are two classes that are used for making Menu; Menu and MenuItem. A Menu is a collection of one or more MenuItem. Each MenuItem can have a Command associated with it. A MenuItem again may further have MenuItem associated with it to make submenus. In this article i will show how to work with menus.
Lets start by looking how to create a Menu (XAML Code).
< Menu Name="Menu1" HorizontalAlignment="Left" VerticalAlignment="Top"/ >
This tag creates a Menu Control. Now lets look at some major properties of Menu Control.
Name --> Defines the name of the menu.
Height --> Defines the Height of the menu
Width --> Defines the width of the menu
Margin --> Defines the position of the menu
Background--> Defines backcolor of the menu
HorizontalAlignment --> Defines the horizontal alignment of the menu inside the parent control.
HorizontalContentAlignment --> Defines the horizontal alignment for the menu content.
VerticalAlignment --> Defines the vertical alignment of the menu inside the parent control.
VerticalContentAlignment --> Defines the content alignment for the menu content.
ToolTip --> defines the tooltip for the menu.
Now that we have seen the major properties its time to see them in action. A Menu tag with all its properties set may look like:
< Menu Height="20" Width="200" Name="Menu1" HorizontalAlignment="Left" HorizontalContentAlignment="Left" VerticalAlignment="Top" VerticalContentAlignment="Top" Background="BlanchedAlmond">
In this sample we have set properties of the menu in XAML, but this is not the only way of doing so. Properties of a menu can be set in three different ways:

Here we create a Menu Item with name as File.
A menu item can in turn have other menu items within it as sub menus. Now lest add some more menu items to our File menu.
< MenuItem Header="_File">
< MenuItem Header="_New"/>
< MenuItem Header="_Open"/>
< Separator/>
< MenuItem Header="_Save"/>
< MenuItem Header="Save _All"/>
< /MenuItem>
Here we have added 4 menu items and a separator to the File Menu
A separator is used to categorize similer menu items. It is added with < Separator/> tag.
We can also add sub menu items to sub menus.
The xaml will look like
< MenuItem Header="_File">
< MenuItem Header="_New"/>
< MenuItem Header="_Open"/>
< Separator/>
< MenuItem Header="_Save">
< MenuItem Header="Save _File"/>
< MenuItem Header="Save A_ll"/>
< MenuItem Header="Save _As"/>
< /MenuItem>
< /MenuItem>
Now lets add a tool tip to our menu item.
< MenuItem Header="_New">
< MenuItem.ToolTip>
< ToolTip>
Create new File
< /ToolTip>
< /MenuItem.ToolTip>
< /MenuItem>
Now lets look at adding and event handler to menu item.
< MenuItem Header="_New" Click="MenuItem_Click"/>
The Click event is used to associate an event handler to the menu item.
And in the code behind
private void MenuItem_Click(object sender, RoutedEventArgs e)
{
MessageBox.Show("Menu item Clicked");
}
WPF Command bindings - Mouse clicks
The following article discusses the WPF command binding
feature with relation to Mouse clicks.
One of WPF powerful features is the binding of commands to controls. If you have used the MVVM design pattern, you will know how useful, powerful, easy, efficient and robust the application gets with WPF commands.
A simple scenario of a command binding would be,
When the button is clicked, first TestCommandCanExecute will be invoked and then as usual TestCommandExecute.
In addition to the simple scenarios of binding a command to a click event we also need to bind specific commands to specific events. For e.g., how about binding one command to Right Click and other to Left click ?
No problems at all. We can use the Mouse bindings to bind a specific command to a specific Mouse event.
Something like this,
The other Mouse actions supported for Mouse bindings are - LeftClick, RightClick, MiddleClick, WheelClick, LeftDoubleClick, RightDoubleClick, MiddleDoubleClick
I have attached an application demonstrating this behavior.

WPF BorderBrush
This article demonstrates the way to work with WPF
BorderBrush.
The Border control in WPF is used to draw a border along the edges of a control. The Border control has a property named BorderBrush which is the drawing brush for the border.
The way we declare the BorderBrush in XAML is different than through code. As we know, XAML automatically converts string to a specific type.
The following code demonstrates use of the Border element,
The above code has a StackPanel containing a Border for a TextBox. The BorderBursh is assigned a Blue color. This means, the Border will be a SolidColorBrush of Blue color. SolidColorBrush is the default WPF Brush.
Now, we will see how to interact with the BorderBrush in code-behind. The scenario we will look at is, finding the current color of the BorderBrush and if Blue then changing it to Red. The following code demonstrates the same,

brdr.BorderBrush = new SolidColorBrush(Color.Red);
WPF Menu Shortcut and Hot keys
We often use Menu items in our forms having Hot keys and
shortcut keys. This is a little bit tricky to use in WPF.
In Windows forms we had an options of adding "&" before the letter we wanted to be the Hot Key. In WPF this is changed to "_".
Running this will display a "_", indicatin a hot key, for "F"
For providing shortcut keys you need to use the InputGestureText property,
I have added a submenu item which will be invoked using the Ctrl+X key. Just adding the InputGesture won't actually fire the menu event. We need to also handling the event. This can be done in two ways, either hook to the key strokes to see if "Ctrl+X" is pressed or bind the Command using a Command binding.
This can be done as follows,
In Windows forms we had an options of adding "&" before the letter we wanted to be the Hot Key. In WPF this is changed to "_".
<Menu DockPanel.Dock="Top">
<MenuItem Header="_File">
</MenuItem>
</Menu>
Running this will display a "_", indicatin a hot key, for "F"
For providing shortcut keys you need to use the InputGestureText property,
<Menu DockPanel.Dock="Top">
<MenuItem Header="_File">
<MenuItem Header="Exit" InputGestureText="Ctrl+X">
</MenuItem>
</MenuItem>
</Menu>

Executed="ExecutedCustomCommand"
CanExecute="CanExecuteCustomCommand" />
</Window.CommandBindings>
<Menu DockPanel.Dock="Top">
<MenuItem Header="_File">
<MenuItem Header="Exit"
Command="{x:Static custom:Window1.MenuRoutedCommand}"
</MenuItem>
</MenuItem>
</Menu>
code behind,
public static RoutedCommand MenuRoutedCommand = new RoutedCommand();
public void ExecutedCustomCommand(object sender, ExecutedRoutedEventArgs e)
{
MessageBox.Show("Executed");
}
public void CanExecuteCustomCommand(object sender,
CanExecuteRoutedEventArgs e)
{
Control target = e.Source as Control;
if (target == null)
{
e.CanExecute = false;
return;
}
e.CanExecute = true;
}
public Window1()
{
InitializeComponent();
CommandBinding customBinding = new CommandBinding(
MenuRoutedCommand, ExecutedCustomCommand, CanExecuteCustomCommand);
KeyGesture CloseCmdKeyGesture = new KeyGesture(
Key.X, ModifierKeys.Control);
CustomRoutedCommand.InputGestures.Add(CloseCmdKeyGesture);
}
