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).

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
