如何以编程方式退出WPF应用程序?

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。

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。

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

要退出应用程序，您可以调用

System.Windows.Application.Current.Shutdown();

如应用程序文档中所述。你也可以通过指定ShutdownMode来修改应用程序的关机行为:

在以下情况下，Windows Presentation Foundation (WPF)会隐式调用Shutdown: 当ShutdownMode设置为OnLastWindowClose时。当关机模式设置为OnMainWindowClose时。当用户结束会话，而SessionEnding事件未被处理或在未取消的情况下被处理时。

请注意Application.Current.Shutdown();只能从创建Application对象的线程调用，即通常是主线程。

总结一下，有几种方法可以做到这一点。

1)终止进程，跳过结束、错误处理等:
