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 });
    }
}

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。

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。

根据需要使用以下任何一种方法:

1.

 App.Current.Shutdown();
OR
 Application.Current.Shutdown();

2.

 App.Current.MainWindow.Close();
OR
 Application.Current.MainWindow.Close();

以上所有的方法都会调用Window类的关闭事件，并且执行可能会在某个时候停止(因为通常应用程序会设置像'are you sure?或“关闭前要保存数据吗?”，在窗口完全关闭之前)

3.但如果您想立即终止应用程序而不发出任何警告。使用下面的

Environment.Exit(0);

如果你使用application . current . shutdown()来退出应用程序，你可能会得到一个System. current . shutdown()。调用线程不能访问该对象，因为它属于另一个线程。如果从不同的线程调用它。要解决这个问题，您可以像这样包装调用

Application.Current.Dispatcher.Invoke(() => Application.Current.Shutdown());
