What is the equivalent of a 'friend' keyword in C Sharp?

Question

What is the equivalent of a \'friend\' keyword in C Sharp?

How do I use the \'internal\' keyword?

I have read that \'internal\' keyword is a replacement for \'fr

Answer 1

No, "internal" is not the same as "friend" (at least the C++ 'friend')

friend specifies that this class is only accessible by ONE, particular class.
internal specifies that this class is accessible by ANY class in the assembly.
