//我发现昨天的关于判断哪国人大招呼素衣永委托代替枚举判断有问题啊，试两数据场景。比如枚举方式参数是传哪国人，自行判断，而委托我告诉他去判断哪国人久试哪国人

// 事件在哪些场景中会使用？
// Winform--WPF--请求级事件--Webform
// 事件可以把固定动作写好，把可变动作分离出去，在满足条件的情况下执行可变动作，相当于对外开放了一个接口，由外部任意扩展
// 正是因为有这个特点，这就是正是封装框架所需要的，框架可以支持扩展
//控件事件：
//启动Form---初始化控件Button---Click +=动作
// 点击按钮--鼠标操作--系统收集信号--判断发给程序---程序接受信号--判断控件--登录-(事件只能在所在类的内部触发)Button触发Click
// 点击按钮--鼠标操作--系统收集信号--判断发给程序---程序接受信号--判断控件--支付-(事件只能在所在类的内部触发)Button触发Click
//把公共部分的逻辑封装起来，把可变的逻辑通过事件发布出来；
//这里两个按钮大部分的逻辑是一样的，可变的逻辑仅仅只是在注册到事件的方法里面
//Event:权限控制，防止外部乱来；
