What is delegates in C# and uses of delegates?

C# delegates are same as pointers to functions, in C or C++. A delegate Object is a reference type variable that use to holds the reference to a method. The reference can be changed at runtime which is hold by an object of delegate, a delegate object can hold many functions reference which is also known as Invocation List that refers functions in a sequence FIFO, we can new functions ref in this list at run time by += operator and can remove by -= operator.

Delegates are especially used for implementing events and the call-back methods. All delegates are implicitly derived from the System.Delegate class.
