What protected internal access modifier

Can I just add that the CLR also caters for protected AND internal access but (apart from reflection emit) this is not supported by either C# or VB.NET.

I believe there were two reasons for this:

1. The language designers didn't think it would be used much, if at all.

2. They couldn't think of a suitable name for it anyway :)

However, it is supported in C++/CLI ( as 'protected private') for anyone who uses that language.

Internal- You can access withing that assembly.
Protected- you can access it in child classes.


So protected internal will be a combination of both. You can access within the same assembly as well as child classes present inside other assembly.
Let me tell you smalll example.
I have assembly1, assembly2

In assembly1 i have a parent Class Vehicle.
In the same assembly i have a class Car derived from vehicle.

Now in assembly2 , i have class Bus derived from vehicle(Assembly1).

Now if i have 2 methods CalculateMileage, GetFuelCapacity

Calculate Mileage i declared it as internal access specifier and GetFuelCapacity i declared it as protectedinternal.

Now when i check the methods for Bus, i can see only GetFuelCapacity, thats because its declared as protected internal.
Hope this would help you to understand well..

It means Protected Or Internal.

==>Accessible anywhere in same assembly it is created + Sub classes in other assembly.


Check this is correct answer if it helped.
