Answer 1

This can all be done easily with linq. This will find any types that are a subclass of generic base class GenericBaseType.

    IEnumerable allTypes = Assembly.GetExecutingAssembly().GetTypes();

    IEnumerable mySubclasses = allTypes.Where(t => t.BaseType != null 
                                                            && t.BaseType.IsGenericType
                                                            && t.BaseType.GetGenericTypeDefinition() == typeof(GenericBaseType<,>));
