Reflection and Generic Types 

From the point of view of reflection, the difference between a generic type and an ordinary type is that a generic type has associated with it a set of type parameters (if it is a generic type definition) or type arguments (if it is a constructed type). A generic method differs from an ordinary method in the same way.

The problem in reflection is to provide a way to examine this array of type parameters or type arguments. In the case of type parameters, reflection must also provide a way of examining the constraints. This section describes the methods of the Type and MethodInfo classes that provide the ability to examine generic types and methods.

  Explains the two key things you need to know to understand reflection over generic types and methods, and introduces the most important properties and methods that unlock generics.

• How to: Examine and Instantiate Generic Types with Reflection
  Shows how to use the properties and methods of Type and MethodInfo to examine generic types.
