Famous Delegates In C# Example Ideas. In c#, the caller passes the logic to callee and callee executes that logic. All delegates are implicitly derived from the system.delegate class.

Delegates play a major role in c# (e.g. In the above event example, similar to the delegate example, we have added the references of methods in the invocation list and then we invoked an event using the invoke method.

There are three steps involved while working with delegates: It is a reference type data type and it holds the reference of a method.;
Delegates Can Be Chained Together;
A delegate type is defined using the following three parts. A delegate is an object or a type that can refer to a method (holds a reference to a method). In c#, a delegate is a type that represents references to methods with a particular parameter list and returns type and is similar to pointers to functions, in c or c++.
