如何防止子类派生自框架基类

Question

Writing MVC application and found this technique to be useful: http://forums.asp.net/post/4960505.aspx which basically puts a class-in-the-middle that overrides an event handler method for execution when any correctly derived Controller subclass Action is requested.

Is there a way I can force all not yet written Controllers in the project/solution to derive from the intended subclass-in-the-middle and/or to not be able to derive from the framework base class?

Answer 1

Instead of using a custom base type for every controller, could you accomplish your goal by using a Global ActionFilter?
