Question

I have an interface like that:

 public interface IViewA : IViewB, IViewC
 {
    byte prop { get; set; }
 }

and I have a generic method like that:

public void OpenPopup<T>(WindowState state)
{
    if ((typeof(T) as IViewC)!=null)
    {
         //Process A
    }
    else
    {
        //Process B
    }

}

Although I send T as an interface which derives from IViewC, Process A is not being processed.

So how to learn at runtime via reflection whether an interface derives from other interface?

thanks

Try the following

if ( typeof(IViewC).IsAssignableFrom(typeof(T)) { 
  ...
}
