#306 – Protected Class Members

Class members marked with the accessibility keyword protected are accessible from within the same class, or from within the code of any classes that derive from the class.

In the picture below, the Dog.DoBark method is marked as protected.  The code in any of the blue blocks can call this method.

Code in a subclass of Dog can call the DoBark method.

    public class Terrier : Dog
        public void TerrierBark()
            // CAN call DoBark from subclass

Code in other classes, not derived from Dog, cannot call the DoBark method.

    public class OtherClass
        public void DoSomething()
            Dog d = new Dog();
            // This class CANNOT call DoBark()
