Hi, This is more a design question... You can't do a decorate design pattern if:

1) The object is marked "sealed" meaning you can't extend from it. 2) or you want to override a method but its not virtual.

What can you do then? Taken that you can't change the class source code if you don't have the source code (like a 3rd party library).
