How to invoke (non virtually) the original implementation of a virtual method?

Question

I have the following situation:

In a 3rd party library (can not be modified):

class A { public virtual void M() {} }

class B : A { public override v         


        

Answer 1

In my previous answer I missed the fact that A and B are in an external library and cannot be modified. In that case, I would suggest a different approach. Basically, if the design flaw is in B, you can’t use B. Subclass from A instead.

The unfortunate consequence of this, of course, is that you may need to reimplement some or all of the functionality in B. You may be able to copy the code from Reflector if necessary. I realise that this sounds undesirable, but I still think it is preferable to using unmodifiable code that has a known issue that causes you problems.
