当通信的`CommunicationState`在`CommunicationState.Opening`中时，是否允许调用`ICommunicationObject.Close（）`？

Question

在IDisposable.Dispose()方法内部，我启动了频道的ICommunicationObject.Close()方法。如果频道的ICommunicationObject.Close()位于CommunicationState，是否可以拨打CommunicationState.Opening？

即。这样的检查是否足以使ICommunicationObject实例关闭？

ICommunicationObject commObj = channel as ICommunicationObject;
if (null != commObj &&
    commObj.State == CommunicationState.Opened ||
    commObj.State == CommunicationState.Opening) {

    commObj.Close();
}

Answer 1

我相信您只需查看commObj.State != CommunicationState.Closed。
