C# and the .NET Framework: The C++ Perspective

Creating and Using Delegates

Delegates are the .NET equivalent of callbacks and function pointers. They are used primarily to route events to handlers as they arrive.

A delegate declaration describes a function signature with a specific pattern of parameters and a specific return type. Once this pattern is established, it might be used to invoke any function with the same signature.

A delegate is declared like this:

__delegate <return type> MyMCDelegate(<parameter list>);

Delegates can have many parameters. The delegate matching pattern ...
