Available Access Modifiers / Specifiers in C# Language

Access Modifiers (Access Specifiers) describes as the scope of accessibility of an Object and its members. All C# types and type members have an accessibility level . We can control the scope of the member object of a class using access specifiers. We are using access modifiers for providing security of our applications. When we specify the accessibility of a type or member we have to declare it by using any of the access modifiers provided by CSharp language.

C# provide five access specifiers , they are as follows :

  • public
  • private
  • protected
  • internal
  • protected internal

public :

public is the most common access specifier in C# . It can be access from anywhere, that means there is no restriction on accessibility. The scope of the accessibility is inside class as well as outside. The type or member can be accessed by any other code in the same assembly or another assembly that references it.

private :

The scope of the accessibility is limited only inside the classes or struct in which they are declared. The private members cannot be accessed outside the class and it is the least permissive access level.

protected :

The scope of accessibility is limited within the class or struct and the class derived (Inherited )from this class.

internal :

The internal access modifiers can access within the program that contain its declarations and also access within the same assembly level but not from another assembly.

protected internal :

Protected internal is the same access levels of both protected and internal. It can access anywhere in the same assembly and in the same class also the classes inherited from the same class .

    I don’t think “Protected Internal” is both protected and internal. It is either protected or internal. within the assembly protected internal members acts as internal members, in other assemblies it acts as protected members.
