Constructor Execution see the difference

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace TestConstructorSeq
{
class Program
{
public class A
{
public A()
{
Console.WriteLine("I am A");
}
static A()
{
Console.WriteLine("I am static A");
}

}
public class B:A
{
public B()
{
Console.WriteLine("I am B");
}
static B()
{
Console.WriteLine("I am static B");
}

}

static void Main(string[] args)
{
B b = new B(); //This outputs
//I am Static B
Console.ReadLine(); //I am Static A
} //I am A
//I am B
}
}
=================================================================================
But this static constructor execution pattern changes in this 3 level inheritance
=================================================================================
class Program

{
public Program()
{
Console.WriteLine("I am p");

}

static Program()
{
Console.WriteLine("I am sp");

}

class Program1:Program

{
public Program1()
{
Console.WriteLine("I am p1");

}

static Program1()
{
Console.WriteLine("I am sp1");

}


}

class Program2 : Program1
{
public Program2()
{
Console.WriteLine("I am p2");

}

static Program2()

{
Console.WriteLine("I am sp2");

}

}

static void Main(string[] args)
{

Program2 p2 = new Program2();
Console.ReadLine();
}
}
}

Dynamic Binding with datahiding query

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using NUnit.FrameWork;


namespace DynamicBindingWithHiding
{
class A
{
public virtual void Whoareyou()
{
Console.WriteLine("I am in A");
Console.ReadLine();
}

}
class B:A
{
public override void Whoareyou()
{
Console.WriteLine("I am in B");
Console.ReadLine();
}

}
class C : B
{
public new virtual void Whoareyou()
{
Console.WriteLine("I am in C");
Console.ReadLine();
}

}
class D : C
{
public override void Whoareyou()
{
Console.WriteLine("I am in D");
Console.ReadLine();
}

}



class Program
{
static void Main(string[] args)
{
//C c = new D();
//c.Whoareyou();

A a = new D();
a.Whoareyou(); //It shows "I am in B" how?

}
}

Points related to Upload and My Album Section
-------------------------------------------------------

1.)The Viewalbum section is now changed to show the latest added photo first for the current

selected album.

2.)The viewallphoto section is also changed to show the latest added photo first in all

photos .


3.)The upload section is now showing the basic and advanced option by using "Advance upload

Button" and "Basic Upload Button" in a more user friendly manner .

4.)In upload section Album selection/Create New and upload photo pages are merged into the single page with the help of javascript.

5) After uploading photos now user will redirect to the MyAlbums section instead of ShowUploadphoto page.

6.)View albums page has been changed to MyAlbums and now the will not show the first album's photo by default .User will have to select the album to show the photos(because default selected album creates the confusion).

7.)Now the page title of every page will change according to the user's current action e.g. if user selects an album then the page title will be changed according to the album's name dynamically .This will happen on every pages and will change with the section accordingly.
