Describe the accessibility modifier protected internal

Hi
  protected internal:-
        "The type or member can be accessed by any code in the same assembly, or by any derived class in another assembly". It means that we can access a "protected internal" method by accessing any instance of it's class in the same assembly, in any class in different assembly which derives from the class, but we won't be able to access the method by accessing an instance of it's class in different assembly.

For more detail see below link:-

hi,

The type or member can be accessed by any code in the assembly in which it is declared, or from within a derived class in another assembly. Access from another assembly must take place within a class declaration that derives from the class in which the protected internal element is declared, and it must take place through an instance of the derived class type.

please refer example.

hope this help.

What you say is basically correct.

'protected internal' (or 'internal protected') when applied to a class member means that the member is accessible from anywhere in the current assembly or by classes in other assemblies which inherit from the class containing the member.
