C# access modifiers: protected internal vs. protected vs. internal

by Oliver 27. January 2011 22:50

As I just read here on msdn, the modifiers protected and internal are orthogonal as in that they can be specified in all combinations and are combined with a logical OR. This means:

  • protected members are accessible from inheriting classes
  • internal members are accessible from classes within the same assembly
  • protected internal classes are accessible from inheriting classes and all classes from the same assembly

The last option is maybe the most unclear – but just imagine a subclass defined in a different assembly and you’ll see what this might be good for :-)

Happy Coding, Oliver
