<!--
MVVM，可以很好的配合WPF的数据绑定机制来实现UI与逻辑代码的分离，
MVVM中的View表示界面，负责页面显示，ViewModel负责逻辑处理，包括
准备绑定的数据和命令，ViewModel通过View的DataContext属性绑定至View，
Model为业务模型，供ViewModel使用
--><!--
ICommand接口中的Execute（）方法用于命令的执行，CanExecute（）方法用于指示当前命令
在目标元素上是否可用，当这种可用性发生改变时便会触发接口中的CanExecuteChanged事件。
我们可以将实现了ICommand接口的命令DelegateCommand赋值给Button（命令源）的Command
属性（只有实现了ICommandSource接口的元素才拥有该属性），这样Button便与命令进行了绑定。
