Wpf usercontrol dispose

窗口關閉時組件“析構”：

  public UserControl()
        {
            InitializeComponent();
                       
            Loaded+= OnLoaded;
        }

        private void OnLoaded(object sender, RoutedEventArgs routedEventArgs)
        {
            Window.GetWindow(this).Closing += OnClosing;
        }

        private void OnClosing(object sender, CancelEventArgs cancelEventArgs)
        {

　　　　　　// 析構
         }

 

 

程序關閉時“析構”：

Dispatcher.ShutdownStarted += DispatcherOnShutdownStarted;

 

  private void DispatcherOnShutdownStarted(object sender, EventArgs eventArgs)
        {
　　　　　　// 析構            

        }
