Answer / ashok

Is this you are trying to do?

class A
{
public int MyName { get; set; }
}

class B : A
{
public int MyName1 { get; set; }
}

public class TestAB
{
public static void Test()
{
A objA = new A();
B objB = new B();

objB = (B)objA; // Unable to cast object of type
'AdvanceLib.A' to type 'AdvanceLib.B'.
objA = objB;

}

}
