C# / .net framework

What is the most reliable way to determine whether a class (type) is a class provided by the .net framework and not any of my classes or 3rd party library classes.

I have tested some approaches

The namespace, e.g. starting with "System."
The Codebase of the assembly, where the dll is located

All this "feels" a little clumsy though it works.

Question: What is the easiest and most reliable way to determine this?

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

C# class can not disguise to be another class because GetType method cannot be override

as seen on Stack Overflow - Search for 'Stack Overflow'
there is a statement in the CLR via C# saying in C#, one class cannot disguise to be another, because GetType is virutal and thus it cannot be override but I think in C# we can still hide the parent implementation of GetType. I must missed something if I hide the base GetType implementation then… >>> More
