I have studied lots of books and materials on internet but I can never understand what is the use of delegate in development. Actually I want to know in what particular situation a developer should use delegate in code. Please provide me some example.

0	Delegate is used to represent one or more functions. It is not a member of a class, but similar to a class. To consume any delegate, we need to create an object to delegate. It is type that references a method. Delegates are the backbone for events. Delegate method can be invoked like any other method with parameters and written value. Types of delegates. Single cast delegate: it represent one function. multi cast delegate: it represent more than one function. Ray.chayan, if this helps please login to Mark As Answer. \| Alert Moderator

0	In the .NET environment, a delegate is a type that defines a method signature and it can pass a function as a parameter. In simple words we can say delegate is a .NET object which points to a method that matches its specific signature. A delegate is a form of type-safe function pointer used by the Common Language Infrastructure.
