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
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;
