.NET interview questions: – What is public, private, protected, internal and internal protected?

Answer:

In the following manner we can describe the C# access modifiers: –

Public – The members (Functions & Variables) declared as public can be accessed from anywhere.

Private – Private members cannot be accessed from outside the class. This is the default access specifier for a member, i.e if you do not specify an access specifier for a member (variable or function), it will be considered as private. Therefore, string PhoneNumber; is equivalent to private string PhoneNumber;

Protected – Protected members can be accessed only from the child classes.

Internal – it can be accessed only within the same assembly.

Internal Protected – internal protected can be accessed within the same assembly as well as in derived class.
