Unlike C+ function pointers, however, delegates are fully object oriented, and unlike C+
2、pointers to member functions, delegates encapsulate both an object instance and a method. A delegate declaration defines a class that is derived from the class System.Delegate. A delegate instance encapsulates an invocation list, which is a list of one or more methods, each of which is referred to a
3、s a callable entity. For instance methods, a callable entity consists of an instance and a method on that instance. For static methods, a callable entity consists of just a method. Invoking a delegate instance with an appropriate set of arguments causes each of the delegates callable entities to be
4、invoked with the given set of arguments. An interesting and useful property of a delegate instance is that it does not know or care about the classes of the methods it encapsulates; all that matters is that those methods be compatible with the delegates type. This makes delegates perfectly suited for “anonymous” invocation. 1.1 Delegate declarations A delegate-declaration is a type-declaration that declares a new delegate type. delegate-declaration: attrib
