You can grab the UI Dispatcher from the static application instance: Application.Current.Dispatcher
您可以从静态应用程序实例application . current. Dispatcher获取UI Dispatcher
You may want to check Application.Current for null first, as it can be cleared during a shutdown sequence.
您可能需要检查应用程序。首先为null的电流，因为在关机序列中可以清除它。
