Is there a way to make derived classes override ToString()?

(I'm working in .NET 4.0 beta, C#.)

I have an interface, and all classes derived from this interface should implement custom ToString() logic. Is that enforceable? If so, how?

Not through an interface.

You'll need to use an abstract class for this.

-- Edit

You can just re-declare 'ToString' as abstract:

abstract class Foo
{
    public override abstract string ToString ();
}
