new keyword in method signature

by

New keyword reference from MSDN:

MSDN Reference

Here is an example I found on the net from a Microsoft MVP that made good sense:
Link to Original

public class A
{
   public virtual void One();
   public void Two();
}

public class B : A
{
   public override void One();
   public new void Two();
}

B b = new B();
A a = b as A;

a.One(); // Calls implementation in B
a.Two(); // Calls implementation in A
b.One(); // Calls implementation in B
b.Two(); // Calls implementation in B

Override can only be used in very specific cases. From MSDN:

You cannot override a non-virtual or
static method. The overridden base
method must be virtual, abstract, or
override.

So the ‘new’ keyword is needed to allow you to ‘override’ non-virtual and static methods.
