Not too sure about the operator overloading, I know it can be done, I've
just never needed to do it myself. As far as 'friends' go, there is no
polymorphism in C#, so you are either a derived class or you are not.
'protected' elements are visible to derived classes, but not to calling
classes. 'public' is visible to all, 'private' is restricted to the
defining class and is not visible to derived classes.
