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

As mentioned, you cannot cast it directly. One possible solution is to have those generic types inherit from a non-generic interface, in which case you can still invoke methods on it without reflection. Using reflection, you can pass the mapped object to any method expecting it, then the cast will be performed for you. So if you have a method called Accept expecting a MessageProcessor as a parameter, then you can find it and invoke it dynamically.
