C# WCF:奇怪的通信对象AbortedException

在WCF中，我认为我可以处理所有的情况，在这些情况下，客户端可以通过订阅关闭和故障事件（如下所示）而出现故障

private ConcurrentDictionary<string,ICallback> dict=new ConcurrentDictionary<string,ICallback>();

public void Initialize(IClientChannel channel)
    {

        channel.Closed += new EventHandler(disconnected);
        channel.Faulted += new EventHandler(disconnected);
    }

   private void disconnected(object sender, EventArgs e)
   {
    //Remove from dict
   }

wcf服务的堆栈跟踪如下所示

但是它们只解释了如何检测我已经实现的死客户端案例。
您的IsChannelValid方法没有遵循正确的方法。你可以通过这样做来结束比赛


检查ICommunicationObject.State属性的值是竞争条件，不建议用于确定是否重用或关闭通道
