[Gtk-sharp-list] Object madness.

Hi.

This will not work! o is an Object and no method 'method()' exists
there. It is not supposed to work either. 

The below example does something, that perhaps is what you want? This
can also be done by interfacing.

using System;

public class Class1
{
  public virtual void foo() {
    Console.WriteLine("Class1");
  }
}

public class Class2 : Class1
{
  public override void foo() {
    Console.WriteLine("Class2");
  } 
}


public class Myclass
{
  public Myclass () {
    Class1 c = new Class2();
    c.foo();
  }

  public static void Main() {
    new Myclass();
  }
}
