Control-side development: The control end sends a control code to the server, the service end (Trojan program) receives the control code, according to the control request, completes the specified request, if the server completes the work, returns the successful information. Development of the control side: Control code settings you can set yourself, do not need to be detailed, there are the

"face-changing" capability, they can be used on many occasions to gracefully address some previously intractable problems (usually, we used reflection to solve the problem), such as: (1) "Generic parameter types are dynamic", using dynamic proxies to solve this problem can not only avoid the performance loss caused by reflection, but also gain the benefit of strongly typed method invocation. (2) "Face" for a group of types. For example, Windows controls such as TextBox,
