delegate 和 观察者模式

[realljx]

delegate是否是 完全实现了 观察者模式(observer)？

两者的区别在哪里？

see "Observer" in Enterprise Solution Patterns Using Microsoft .NET

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnpatterns/html/DesObserver.asp

The event and delegate features in the .NET Framework implement this approach as a language construct so that you do not even have to implement your own ConcreteSubject classes anymore. Basically, events replace the ConcreteSubject classes, and delegates implement the role of the Observer interface.
