WCF服务通道中出现CommunicationObjectAbortedException异常，同时加载多个数据。

c#wcfnettcpbinding
8

我在我的客户端-服务器应用程序中使用WCF服务，但在服务器和客户端之间通信时遇到以下错误。

Error Message =>> System.ServiceModel.CommunicationObjectAbortedException: The communication object, System.ServiceModel.Channels.ServiceChannel, cannot be used for communication because it has been Aborted.

Server stack trace: 
   at System.ServiceModel.Channels.CommunicationObject.ThrowIfDisposedOrNotOpen()
   at System.ServiceModel.Channels.ServiceChannel.Call(String action, Boolean oneway, ProxyOperationRuntime operation, Object[] ins, Object[] outs, TimeSpan timeout)
   at System.ServiceModel.Channels.ServiceChannelProxy.InvokeService(IMethodCallMessage methodCall, ProxyOperationRuntime operation)
   at System.ServiceModel.Channels.ServiceChannelProxy.Invoke(IMessage message)

Exception rethrown at [0]: 
   at System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage(IMessage reqMsg, IMessage retMsg)
   at System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke(MessageData& msgData, Int32 type)
   at ServiceLib.ServiceCallbackInterfaces.IHostServiceCallback.SendEventAndStatus(String message, Boolean isBackupGenerated)
   at ServiceLib.Services.DriversService.objDriver_EventReceived(Object sender, EventReceivedEventArgs e)

应用场景：客户端通过WCF服务并使用nettcp绑定从服务器获取数据。服务器连接实际设备，并每秒生成20-30个事件。生成的事件作为字符串消息通过WCF的回调接口推送到所有连接的客户端。如果客户端没有任何进程负载（仅接收事件并显示），则运行良好。但是，当我们在客户端进行一些加载过程并忙碌一段时间时，会出现错误。
注意：我已经设置了nettcp绑定中的所有超时时间的最大值，但问题仍未解决。
NetTcpBinding tcpBinding = new NetTcpBinding(SecurityMode.None);
                tcpBinding.MaxBufferPoolSize = 2147483647;
                tcpBinding.MaxReceivedMessageSize = 2147483647;
                tcpBinding.MaxBufferSize = 2147483647;
                tcpBinding.ReaderQuotas.MaxStringContentLength = 2147483647;
                tcpBinding.ReaderQuotas.MaxDepth = 2147483647;
                tcpBinding.ReaderQuotas.MaxBytesPerRead = 2147483647;
                tcpBinding.ReaderQuotas.MaxNameTableCharCount = 2147483647;
                tcpBinding.ReaderQuotas.MaxArrayLength = 2147483647;
                tcpBinding.SendTimeout = TimeSpan.MaxValue;
                tcpBinding.ReceiveTimeout = TimeSpan.MaxValue;
                tcpBinding.ReliableSession.InactivityTimeout = TimeSpan.MaxValue;

请指导我是否需要与通信渠道或绑定相关的其他设置？

检查服务是否抛出任何异常-未处理的异常会使通道故障；这可能不是绑定问题。 - Tim

按照 @Tim 的说法，要实现这个功能，可以使用 Service Trace Viewer，网址是 http://msdn.microsoft.com/zh-cn/library/ms732023.aspx。 - Jeremy McGee
@JeremyMcGee：我对如何使用服务跟踪查看器没有太多的了解。你能指导一下我吗？ - Upendra Chaudhari
@UpendraChaudhari - 请检查Jeremy发布的链接。 - Tim
确实。实质上，您需要调整配置以创建跟踪文件，然后使用跟踪查看器查看。我建议同时追踪客户端和服务器。还值得记住，您也可以跟踪序列化问题：http://msdn.microsoft.com/en-us/library/dd788183(v=bts.70).aspx - Jeremy McGee

正如您在问题中提到的，您已将所有超时设置为最大值。因此，在我看来，您定义的InstanceContextMode可能存在问题。您在服务中定义了哪种模式？PerSession、PerCall还是Single？如果您定义了PerCall并且使用相同对象（服务的全局声明对象）调用服务，则可能会导致通道进入故障状态或连接断开。

因此，如果您定义了PerSession模式，则从客户端使用单个对象（全局声明）获取来自服务的数据。如果您定义了PerCall选项，则每次创建新对象。

希望这可以帮助您。请随时提出任何疑问......

我有多个服务，其中一个名为 HostService 的主要服务具有 PerSession 模式，而所有其他服务都具有 PerCall 模式。在主服务中，我使用静态哈希表维护连接的客户端列表，因为我需要使用回调方法向所有客户端推送事件。因此，我将所有已连接客户端的上下文对象存储在该列表中。在客户端方面，我每次都会创建新对象来调用服务。 - Upendra Chaudhari
请问你能描述一下如何向所有客户端发送事件通知吗？我的意思是，你可以提供一些代码吗？还有一件事是，当你向客户端发送事件通知时，同时调用了另一个以 PerCall 模式运行的服务？ - Chief
正如我之前告诉你的那样，我正在使用回调方法发送事件通知。当我在客户端应用程序中更改工作模式（监督员、设置、离线）时，我会调用EventLogService来保存工作模式数据，以便它作为服务器通知显示给所有连接的客户端。 - Upendra Chaudhari
您能否通过将PerSession模式更改为EventLogService，并使用全局声明的对象在客户端调用服务来检查它。 - Chief
是的，我通过执行 PerSession 和全局对象进行了检查，一切都正常。我不知道实际问题是什么，但现在对我来说一切正常。感谢您的支持。 - Upendra Chaudhari
