What are Access Modifiers in C#?

Access Modifiers are basically used to control the accessibility of types and members with in the types. In C# there are 5 different types of Access Modifiers.

1. Public: Public is the most common access specifier in C#. It can be accessed from anywhere, that means there is no restriction on accessibility. It is accessible to all classes & projects.

2. Private: The range of the accessibility is limited only within the classes or struct in which they are declared.

3. Protected: All members in the current class & in derived classes can access the variables.

4. Internal: The type or member can be accessed by any code in the same assembly, but not from another assembly.

5. Protected Internal: The protected internal access specifier allows a class to hide its member functions & member variables from other class objects and functions, except a child class within the same application. This is also used while implementing inheritance.
