Try

App.Current.Shutdown();

对我来说

Application.Current.Shutdown(); 

没有工作。

另一种方法是:

System.Diagnostics.Process.GetCurrentProcess().Kill();

这将强制终止应用程序。它总是有效的，即使在多线程应用程序中也是如此。

注意:注意不要在另一个线程中丢失未保存的数据。

如果你想从另一个没有创建应用程序对象的线程中退出，请使用:

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。

Application.Current.ShutdownMode = ShutdownMode.OnExplicitShutdown;

这应该可以达到目的:

Application.Current.Shutdown();
