Question

我正在使用WCF服务从MSMQ中获取消息。我发现有些消息没有被提取，我不知道为什么。我该如何尝试调试？我没有看到任何错误被抛出，服务只是没有从队列中取消消息。我正在使用MsmqMessage来排队/出列消息。

邮件大小：146,000字节（不是那么大）。

我发现：如果我减少了邮件大小（删除了一些内容）。所以它可能与尺寸相关，也可能是内容。但是在xml中没什么了不起的。

有什么想法吗？

服务配置：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <appSettings>
    <!-- use appSetting to configure MSMQ queue name -->
    <add key="QueueName" value=".\private$\MyMessageQueue" />
    <add key="baseAddress" value="http://localhost:8000/test/message" />
  </appSettings>
  <system.serviceModel>
    <services>
      <service behaviorConfiguration="MessageServiceBehavior" name="WcfServiceClient.MessageServiceClient">
        <!-- .Net endpoint-->
        <endpoint address="msmq.formatname:DIRECT=OS:.\private$\MyMessageQueue"
                  binding="msmqIntegrationBinding"
                  bindingConfiguration="DotNetBinding"
                  contract="WcfServiceClient.IMessageProcessor" />
        <endpoint
                  address="mex"
                  binding="mexHttpBinding"
                  contract="IMetadataExchange" />
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="MessageServiceBehavior">
          <serviceDebug includeExceptionDetailInFaults="true" />
          <serviceMetadata />
          <!--<serviceThrottling maxConcurrentCalls="20" maxConcurrentSessions="20" />-->
          <serviceTimeouts />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <bindings>
      <msmqIntegrationBinding>
        <binding serializationFormat="ActiveX" name="ActiveXBinding" durable="true" exactlyOnce="true">
          <security mode="None" />
        </binding>
        <binding serializationFormat="Xml" name="DotNetBinding" durable="true" exactlyOnce="true">
          <security mode="None" />
        </binding>
      </msmqIntegrationBinding>
    </bindings>
  </system.serviceModel>
</configuration>

修改当我打开跟踪时（刚想出来）我得到了这个？对我没有任何意义吗？

Answer 1

例外

System.ServiceModel.CommunicationObjectAbortedException: The communication object, System.ServiceModel.Channels.TransportReplyChannelAcceptor+TransportReplyChannel, cannot be used for communication because it has been Aborted.

表示TransportReplyChannel已经关闭。

您能提供显示您如何从队列中读取的源代码吗？队列对象关闭/处理后可能还有一个额外的读取？
