What are the different accessibility levels in .NET?

The five levels of access modifiers are as follows:-

• Private: The members of the class only have the access.
• Protected: All the members in current class & in derived classes can access the variables.
• Friend (internal in the C#):- Only the members in current project have access to the elements.
• Protected friend (protected internal in the C#) :- All members in the current project & all members in derived class can access the variables.
• Public: - All the members have access in all classes and projects.
