Question

I have

public class ViewBaseBase : UserControl

Then I have

public class ViewBase<TPresenter, TIView> : ViewBaseBase

Which leads of course to

public class AView : ViewBase<ConcretePresenter, IView>

The reasoning goes, I’d like a non generic way to access ViewBase polymorphically without knowing TPresenter, TIView.

Does this look “wrong” to anyone? I don’t know, it works, it doesn’t seem to be causing me problems, but it feels “wrong” some how. Possibly it’s the ViewBaseBase name, I could probably use an interface instead, but actually I quite like having the UserControl inheritance at that level as all ViewBase must be a UserControl…

Answer 1

There’s not much you can do unless you have a non-generic absolute base class, if you wish to access this stuff polymorphically. You’ve also said that every ViewBase must be a UserControl, but that doesn’t mean you can’t use interfaces. Consider this:

public interface IViewBase
{
}


public abstract class ViewBase<IPresneter, TIView> : UserControl
                                                   , IViewBase
{
}


public class AView : ViewBase<ConcretePresenter, IView>
{
}

AView is now a UserControl and a IViewBase. I personally think this is cleaner.
