Internal vs. Private Access Modifiers

Question

What is the difference between the internal and private access modifiers in C#?

Answer 1

internal members are accessible within the assembly (only accessible in the same project)

private members are accessible within the same class

Example for Beginners

There are 2 projects in a solution (Project1, Project2) and Project1 has a reference to Project2.

• Public method written in Project2 will be accessible in Project2 and the Project1
• Internal method written in Project2 will be accessible in Project2 only but not in Project1
• private method written in class1 of Project2 will only be accessible to the same class. It will neither be accessible in other classes of Project 2 not in Project 1.
