wpf - 取消在WPF中关闭窗口

Question

我知道这个问题与this one非常相似，但是我认为以下代码可以取消关机请求，但是不是吗？谁能解释为什么？

namespace WpfApplication1
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            this.Closing += new System.ComponentModel.CancelEventHandler(MainWindow_Closing);            

        }

        private void button1_Click(object sender, RoutedEventArgs e)
        {
            Application.Current.Shutdown();
        }

        void MainWindow_Closing(object sender, System.ComponentModel.CancelEventArgs e)
        {
            e.Cancel = true;
        }        
    }
}

从MSDN:

Important: When Shutdown is called, the application will shut down irrespective of whether the Closing event of any open windows is canceled.
