Delegates Tutorial (C#) This tutorial demonstrates the delegate types. It shows how to map delegates to static and instance methods, and how to combine them (multicast). Sample Files Further Reading Tutorial A delegate in C# is similar to a function pointer in C or C++. A delegate declaration defines a type that encapsulates a method with a particular set of arguments and return type. An interesting and useful property of a delegate is that it does not know or care about the class of the object that it references. Note Delegates run under the caller's security permissions, not the declarer's permissions. This tutorial includes two examples: Example 1 shows how to declare, instantiate, and call a delegate. In addition, it discusses the following topics: Delegates and Events Delegates vs. Example 1 The following example illustrates declaring, instantiating, and using a delegate. The use of delegates promotes good separation of functionality between the bookstore database and the client code. Output Code Discussion
