C# Question

How can I get all the inherited classes of a base class?

class Foo { }

class Foo1 : Foo { }

class Foo2 : Foo { }

How would I be able to get all the classes that use Foo as a base class? The inherited classes aren't necessary in the same assembly.

This is not fast, but as long as Foo is a concrete type (not an interface), then it should work. Foo itself is not returned by this code.

                       .SelectMany(assembly => assembly.GetTypes())
                       .Where(type => type.IsSubclassOf(typeof(Foo)));
