Access modifiers in C#

Access Modifiers
=================

Public
can be accessed by any other code in the same assembly or another assembly that references it.

Private
can only be accessed by code in the same class or struct.

Protected
can only be accessed by code in the same class or struct, or in a derived class.

Internal
can be accessed by any code in the same assembly, but not from another assembly.

Protected Internal
can be accessed by any code in the same assembly, or by any derived class in another assembly.

Some points

1) structs members cannot be declared as protected because they doesn't support inheritance.
2) destructors cannot have access modifiers.
3) internal is the default access modifier for class, struct, interface.
4) Interface members are always public.
5) Enumeration members are always public.
