Hello P,

Use [System.Runtime.CompilerServices.InternalsVisibleTo Attribute] which allows
you to specify assemblies which have access to non-public types within the
assembly to which you apply the attribute

Doesn't that depend on which "friend" you are talking about? I know the OP
wasn't clear. Internal is equivalent to VB Friend, but it is not equivalent
to C++ friend.

The friend access modifier in C++ allows you to be very specific as to who
your friends are. Internal in C# means simply that anyone in the assembly
can access this. Internal is similar, but not equivalent, to C++ friend.

internal carries a similar meaning, is not the same though.

What is exactly what you need to do? Maybe we can suggest you the way to go.

If you mean the VB notion of 'Friend', then see the other posts ("internal").
If you mean the C++ notion of 'friend', then no equivalent exists in C#.

The way we implement the "friend" concept is by making the method public,
and testing that the caller is one of a set of particular methods or
classes.

I think I don't like it, but it does do the job.

You're right, of course. I did not think of the C++ friend access modifier,
as I assumed (point of failure) that if the poster was asking the question,
he was a VB developer.
