【中文标题】当channel的CommunicationState处于CommunicationState.Opening时，是不是允许调用ICommunicationObject.Close()？

【英文标题】：Is it allowed to call ICommunicationObject.Close() when the CommunicationState of channel is being in CommunicationState.Opening?当channel的CommunicationState处于CommunicationState.Opening时，是否允许调用ICommunicationObject.Close()？

【问题描述】：

在IDisposable.Dispose() 方法内部，我启动了我频道的ICommunicationObject.Close() 方法。当频道的CommunicationState为CommunicationState.Opening时，是否允许调用ICommunicationObject.Close()？

即对于ICommunicationObject 实例关闭，这样的检查是否足够？

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

    commObj.Close();

【参考方案1】：

我相信您可以简单地查看commObj.State != CommunicationState.Closed。

多年来，我一直在运行A smarter WCF service client 的变体，没有出现任何问题。
