当用户从文件菜单中单击退出菜单项时,应该如何退出应用程序?
我试过:
this.Dispose();
this.Exit();
Application.ShutDown();
Application.Exit();
Application.Dispose();
还有很多其他的。没有什么工作。

if (System.Windows.Forms.Application.MessageLoop)
{
// WinForms app
System.Windows.Forms.Application.Exit();
system.Environment.Exit(1);
}

根据我的理解,Application.Current.Shutdown()也有它的缺点。
如果你想显示一个确认窗口让用户确认是否退出,Application.Current.Shutdown()是不可逆的。
Caliburn微调味
public class CloseAppResult : CancelResult
{
public override void Execute(CoroutineExecutionContext context)
{
Application.Current.Shutdown();
base.Execute(context);
}
}
public class CancelResult : Result
{
public override void Execute(CoroutineExecutionContext context)
{
OnCompleted(this, new ResultCompletionEventArgs { WasCancelled = true });
}
}
if (System.Windows.Forms.Application.MessageLoop)
{
// WinForms app
System.Windows.Forms.Application.Exit();
system.Environment.Exit(1);
}
我是这样做的:
// Any control that causes the Window.Closing even to trigger.
private void MenuItemExit_Click(object sender, RoutedEventArgs e)
{
this.Close();
}
// Method to handle the Window.Closing event.
private void Window_Closing(object sender, CancelEventArgs e)
{
var response = MessageBox.Show("Do you really want to exit?", "Exiting...",
MessageBoxButton.YesNo, MessageBoxImage.Exclamation);
if (response == MessageBoxResult.No)
{
e.Cancel = true;
}
else
{
Application.Current.Shutdown();
}
}
我只从主应用程序窗口调用application . current . shutdown(),所有其他窗口都使用this.Close()。在我的主窗口中,Window_Closing(…)处理右上角的x按钮。如果任何方法调用窗口关闭器,如果用户确认,Window_Closing(…)将捕获关闭事件。
The reason I do in fact use Application.Current.Shutdown() in my main window is that I've noticed that if a design mistake was made and I haven't declared a parent of one of my windows in an application, if that window is opened without being shown prior to the last active window closing, I'm left with a hidden window running in the background. The application will not shut down. The only way to prevent complete memory leak is for me to go into the Task Manager to shut down the application. Application.Current.Shutdown() protects me from unintended design flaws.
这是我个人的经验。最后,使用最适合您的场景的方法。这只是另一条信息。
App.Current.Shutdown (); 把它写在你需要的地方。
