Polymorphism Through Extension Methods?

Question

I have a class library which contain some base classes and others that are derived from them. In this class library, I\'m taking advantage of polymorphism to do what I want it t

Answer 1

As @SLaks has already stated you cannot call the method as an extension method (even with a dynamic type) ... you can however call the static method with a dynamic type

So, although this will fail

Base base1 = new Child1();
(base1 as dynamic).DoSomething();

This will work

Base base1 = new Child1();
Extensions.DoSomething(base1 as dynamic);
