Get a list of functions for a DLL

Question

I\'m building a project. It\'s an application that users can add their extensions (DLL files) to. To manage an extension, I need to get its list of classes, functions, etc.

Answer 1

For a particular assembly, you can use Assembly.GetTypes to get the types, then for each type call Type.GetMethods(), Type.GetProperties() etc, or just Type.GetMembers().

However, for plugin functionality it's usually a good idea to have a common interface which the plugins have to implement - that reduces the amount of reflection you need to use. Use Type.IsAssignableFrom() to check whether a type is compatible with a particular interface.

You might also want to look at the Managed Extensibility Framework which can make implementing an extension system easier.
