最好是使用

  Application.Current.ShutdownMode = ShutdownMode.OnExplicitShutdown;                                    var login = new LoginWindow();                     login.ShowDialog();             if (null != login.AccountInfo)             {                 this.MainWindow = new MainWindow(login.AccountInfo);                 this.MainWindow.ShowDialog();             }             Application.Current.Shutdown();
