When should methods be made private? [closed]

Answer 1

simple rules:

1. If you are not looking to expose it outside of the class that is using it, make it PRIVATE.

2. If you are looking to expose it inside the same assembly to other classes but not outside the assembly, make it INTERNAL (C#) / Friend (VB.NET).

3. If you are looking to expose the functionality outside the assembly to everyone, make it PUBLIC
