(analogy wo开发者_JAVA百科uld be very helpful). The answer so far on this topic either lacking the three subjects or are not clear enough for me.


Method = a function in a class.

Delegate = a pointer to a Method.

Event = a delegate with special restrictions - it can only be invoked by the class that declares it


Method - a function with some logic.

Delegate - a function pointer. You can think of it as a variable which can reference methods.

Event - a collection of delegates, which you can execute/invoke at will.


A method is a member function.

A delegate is an object that can hold a member-function.

An event is, well, an event. With each event there is one associated delegate. All the methods that are held in the delegate are called when the event is fired
