1st, simple question, is there a protected in C#?

I mean a comparable keyword like the C++ protected, which defines a member
as accessable for decendants, but not for the outside world.

Then, a more complicated question, is privat in C#, then comparable with
protected, or private in C++. Or to say it in other words, if I declare a
member private in C#, can I access it in a decendant class?

The protected and private in C# have the same meaning as in C++. C#
extends access modifiers by adding internal and protected internal,
which are equal to public and protected with respect to the module they
appear in and private to the outer world.

Is that strictly true? I *thought* that in C++, you couldn't access the
private members of one instance from another instance (whereas you can
in C#). This is only based on what others have said, however - I
haven't checked the spec.

There's also the concept of private inheritance in C++, but not in C#.

Yes, you can access the private fields from another instance in C++.

My mistake. It must be another language I'm thinking of... I wonder
which?

None I know of. In fact, "How come instance 1 can access private members of
instance 2?" seems to be a common newbie question about C#, C++, and Java
alike.
 
Actually, C++/CLI has "internal" and also has an equivalent to C#'s protected
internal: "public protected".
