C# 设计模式之命令模式
标签：客户 pat open work ace write space code logs
模式设计的对象：
1、客户角色：发出一个具体的命令并确定其接受者。
2、命令角色：声明了一个给所有具体命令类实现的抽象接口
3、具体命令角色：定义了一个接受者和行为的弱耦合，负责调用接受者的相应方法。
4、请求者角色：负责调用命令对象执行命令。
5、接受者角色：负责具体行为的执行。

141 //=== 命令模式
142 ComandInvoke comandInvoke;//命令使用者
143 CommandMode commandMode;// 命令
144 ComandAction comandAction;//命令实现对象
145 Engineer engineer = new Engineer("Jbt");
146 Worker worker = new Worker("N124");
147
148
149 FactroyCommand factroyCommand = new FactroyCommand(engineer);
150 ClientCommand clientCommand = new ClientCommand(worker);
151
152 comandInvoke = new ComandInvoke(factroyCommand);
153 comandInvoke.Open();
154 comandInvoke.ActionComand = clientCommand;
155 comandInvoke.Open();
