I'm loading custom user controls into my form using reflection. I would like all my user controls to have a "Start" and "End" method so they should all be like:

public interface IStartEnd
{
    void Start();
    void End();
}

public class AnotherControl : UserControl, IStartEnd
{            
    public void Start()
    { }

    public void End()
    { }
}

I would like an interface to load through reflection, but the following obviously wont work as an interface cannot inherit a class:

public interface IMyUserControls : UserControl, IInit, IDispose
{

}
