Why events can't be used in the same way in derived classes as in the base class in C#?

Question

In following code, I want to extend the behaviour of a class by deriving/subclassing it, and make use of an event of the base class:

public class A
{
    pub         


        

Answer 1

The reason the original code doesn't work is because you need to have access to the event's delegate in order to raise it, and C# keeps this delegate private.

Events in C# are represented publicly by a pair of methods, add_SomeEvent and remove_SomeEvent, which is why you can subscribe to an event from outside the class, but not raise it.
