WCF錯誤「套接字連接已處理」

我有一個WCF服務，可以根據輸入參數返回大量數據。WCF錯誤「套接字連接已處理」

該服務作爲ServiceHost可執行文件在我的機器上運行，我現在使用WCF Test客戶端進行測試。

這裏是我的主機配置：

<?xml version="1.0" encoding="utf-8" ?>

     </bindings>   
     <services>   
      <service name="MyCompany.MyApplication.DataServices.ExchangeRepository" 
        behaviorConfiguration="MyCompany.MyApplication.DataServicesBehavior">

          bindingConfiguration="NetTcpBinding_ExchangeRepository" 
          behaviorConfiguration="MyCompany.MyApplication.EndpointBehavior">

       <host> 
        <baseAddresses> 
         <add baseAddress = "net.tcp://localhost:8896/ExchangeRepository/" /> 
         <add baseAddress = "http://localhost:8895/ExchangeRepository/" /> 
        </baseAddresses> 
       </host> 
      </service> 
     </services>   
     <behaviors> 
      <serviceBehaviors> 
       <behavior name="MyCompany.MyApplication.DataServicesBehavior"> 
        <dataContractSerializer maxItemsInObjectGraph="2147483646"/> 
        <serviceMetadata httpGetEnabled="True"/> 
        <serviceDebug includeExceptionDetailInFaults="True" />

       </behavior> 
      </endpointBehaviors> 
     </behaviors>  
    </system.serviceModel> 
</configuration>

這裏是我的客戶端配置：

     </behaviors> 
     <bindings> 
      <netTcpBinding> 
       <binding name="NetTcpBinding_IExchangeRepository" closeTimeout="00:10:00"

        <security mode="None"> 
         <transport clientCredentialType="Windows" protectionLevel="EncryptAndSign" /> 
         <message clientCredentialType="Windows" /> 
        </security> 
       </binding> 
      </netTcpBinding> 
     </bindings> 
     <client> 
      <endpoint address="net.tcp://localhost:8896/ExchangeRepository/" 
       behaviorConfiguration="endpointBehaviour" binding="netTcpBinding" 
       bindingConfiguration="NetTcpBinding_IExchangeRepository" contract="IExchangeRepository" 
       name="NetTcpBinding_IExchangeRepository"> 
       <identity> 
        <dns value="localhost" /> 
       </identity> 
      </endpoint> 
     </client> 
    </system.serviceModel> 
</configuration>

，這裏是我得到的錯誤：

The socket connection has been disposed.

Inner Exception:

的錯誤是發生當返回的數據超過一些記錄數時。用更少的數據一切都按預期工作。

關於如何解決這個問題的任何建議？

第一步是啓用跟蹤 - http://blogs.msdn.com/b/madhuponduru/archive/2006/05/18/601458.aspx – EkoostikMartin

這很難說，但我的猜測是，你有一個'using（）{}'塊在某個地方完成並處理一些東西，而堆棧仍然在傳輸數據。儘管很難獲得幫助，但沒有看到更多（可能還有很多）代碼。 – CodingGorilla

這一切都是由愚蠢的數據問題造成的。錯誤信息絕對沒用。啓用跟蹤允許查看實際的異常。謝謝EkoostikMartin！ –
