WPF实现在电脑重启或关机时执行某些逻辑

Application类的SessionEnding事件，就是电脑关机或重启时响应的(会话结束事件)，

所以只需要在App.xaml中添加SessionEnding

<Application x:Class="DriverEasyWPF.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             StartupUri="MainWindow.xaml" Startup="Application_Startup" SessionEnding="Application_SessionEnding">

并在后台代码中这样实现：

private void Application_SessionEnding(object sender, SessionEndingCancelEventArgs e)
        {
             //your code
        }

但Windows没有SessionEnding事件，那如果要在某个窗口中监听电脑关机或重启呢，

因为Application类是贯穿于整个WPF项目的，所以在其他窗口的后台代码中，这样调用即可：

public MainWindow()
        {
            InitializeComponent();
            App.Current.SessionEnding += Current_SessionEnding;
        }

        private void Current_SessionEnding(object sender, SessionEndingCancelEventArgs e)
        {
            throw new NotImplementedException();
        }

通过 App.Current.SessionEnding += Current_SessionEnding;
