.NET中的Command模式 在ASP.NET的MVC模式中,有一种叫Front Controller的模式,它分为Handler和Command树两个部分,Handler处理所有公共的逻辑,接收HTTP Post或Get请求以及相关的参数并根据输入的参数选择正确的命令对象,然后将控制权传递到Command对象,由其完成后面的操作,这里面其实就是用到了Command模式。 图7 Front C...

技巧:一般情况下,只需要操作一个命令实例与之对应即可。因此程序中的命令多使用单件模式(Singletone Pattern)以减少代码复杂度。 3.指定命令源 命令源拥有命令和命令源两个属性。 同一个命令可以有多个源。 一旦把命令指派给命令源,命令源就会受命令影响,命令不能执行的时候作为命令源的控件不可用。革命临官发送命令...

by now. The reality is that Commands are structurally simple. This section will reinforce your familiarity with the command design pattern, introduce you to its role in the Web Application Framework, and hopefully encourage you to become creative in leveraging this simple, but powerful pattern. ...

Thankfully, there is a solution to this issue: using a command to expose the “event handler” and bind the UI element to that command by using a XAML data-binding. Because data-bindings are evaluated only at run time, they won’t cause a compilation error. And because they are...
