RE: Abstract classes and virtual methods

An abstract class can ONLY be overridden by a virtual method. If the method is not virtual then the abstract method is "hidden".

The "override" also means the member is virtual. For example Derived.Method is a virtual method:

 
public abstract class Base
{
 public abstract void Method ( );
}
 
public class Derived : Base
{
 public override void Method ( )
 {
 }
}
