Cast to generic type in C#

Question

I have a Dictionary to map a certain type to a certain generic object for that type. For example:

typeof(LoginMessage) maps to MessageProcessor

        

Answer 1

The answer of @DanielPlaisted before generally works, but the generic method must be public or one must use BindingFlags.NonPublic | BindingFlags.Instance! Couldn't post it as a comment for lack of reputation.
