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();
}
}
}

//Check out the difference between the two

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?

}
}
}
