我们有一个系统，其中客户端 Flash 应用程序正在调用基于 asmx 的搜索 Web 服务，该 Web 服务又使用 NetTcpBinding 调用托管在 Windows 服务中的 wcf 服务。这在没有时工作正常。的搜索结果很小。但是当搜索结果变大时，在 2000 条记录的范围内，我们在调用 wcf 的 asmx 服务中遇到异常：

`The communication object, System.ServiceModel.Channels.ServiceChannel, cannot be used for communication because it is in the Faulted state.`

为了排查错误，我们开启了服务追踪，发现报错是：

`The socket connection was aborted. This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue. Local socket timeout was '00:01:00'.`

我们增加了服务器和客户端配置中的超时值，并增加了 maxItemsInObjectGraph 值。wcf 调用没有发生错误，因为我们可以对其进行调试，并且观察到的行为是，当 wcf 调用返回时，asmx 服务中的代码会遇到异常块并报告上述错误。

服务器端配置：

<system.serviceModel>
<services>
  <service name="***.SearchController" behaviorConfiguration="serviceBehavior">
    <endpoint address="net.tcp://localhost:8228/SearchController" binding="netTcpBinding" contract="***.ISearch" name="SearchController" />
  </service>
</services>
<behaviors>
  <serviceBehaviors>
    <behavior name="serviceBehavior">
      <serviceDebug includeExceptionDetailInFaults="True" />
      <dataContractSerializer maxItemsInObjectGraph="2147483647"/>
    </behavior>
  </serviceBehaviors>
</behaviors>
<bindings>
  <netTcpBinding>
    <binding name="LargeMessageBinding"
             maxBufferPoolSize="2147483647"
             maxBufferSize="2147483647"
             maxConnections="2147483647"
             maxReceivedMessageSize="2147483647"
             portSharingEnabled="false"
             transactionFlow="false"
             listenBacklog="2147483647"
             closeTimeout="infinite" 
             openTimeout="infinite" 
             receiveTimeout="infinite" 
             sendTimeout="infinite">
      <security mode="None">
        <message clientCredentialType="None"/>
        <transport protectionLevel="None" clientCredentialType="None"/>
      </security>
      <reliableSession enabled="false"/>
      <readerQuotas maxDepth="2147483647"
         maxStringContentLength="2147483647"
         maxArrayLength="2147483647"
         maxBytesPerRead="2147483647"
         maxNameTableCharCount="2147483647" />
    </binding>
  </netTcpBinding>
</bindings>
<diagnostics wmiProviderEnabled="true">
  <messageLogging
         logEntireMessage="true"
         logMalformedMessages="true"
         logMessagesAtServiceLevel="true"
         logMessagesAtTransportLevel="true"
         maxMessagesToLog="3000"
   />
</diagnostics>
<client></client>

客户端（axms）端配置：

<system.serviceModel>
    <client>
  <endpoint address="net.tcp://localhost:8228/SearchController" binding="netTcpBinding" behaviorConfiguration="endpointBehavior" contract="***.ISearch" name="NewSearch"/>
</client>
    <bindings>
  <netTcpBinding>
    <binding name="LargeMessageBinding"
             maxBufferPoolSize="2147483647"
             maxBufferSize="2147483647"
             maxConnections="2147483647"
             maxReceivedMessageSize="2147483647"
             portSharingEnabled="false"
             transactionFlow="false"
             listenBacklog="2147483647"
             closeTimeout="infinite"
             openTimeout="infinite"
             receiveTimeout="infinite"
             sendTimeout="infinite">
      <security mode="None">
        <message clientCredentialType="None"/>
        <transport protectionLevel="None" clientCredentialType="None"/>
      </security>
      <reliableSession enabled="false"/>
      <readerQuotas maxDepth="2147483647"
         maxStringContentLength="2147483647"
         maxArrayLength="2147483647"
         maxBytesPerRead="2147483647"
         maxNameTableCharCount="2147483647" />
    </binding>
  </netTcpBinding>
</bindings>
<behaviors>
  <endpointBehaviors>
    <behavior name="endpointBehavior">
      <dataContractSerializer maxItemsInObjectGraph="2147483647"/>
    </behavior>
  </endpointBehaviors>
</behaviors>
</system.serviceModel>

从 asmx 服务调用 wcf 所使用的代码：

List<***.SearchResult> results;
    using (var searchFactory = new ChannelFactory<***.ISearch>("NewSearch"))
    {
        Legacy.ISearch searchProxy = searchFactory.CreateChannel();
        results = searchProxy.Search(searchOption);
    }

此调用正在报告异常。

即使在配置中增加阈值后，我们也不确定为什么会出现超时问题。可能是该服务没有获取我们的绑定配置并使用一些默认配置值，因此引发了错误。不确定服务是否在运行时实际获取了我们的配置的验证方法是什么。在解决此问题时需要帮助。

你必须在你的应用程序中使用绑定，但你只声明它，使用bindingConfiguration属性

<endpoint address="net.tcp://localhost:8228/SearchController" binding="netTcpBinding" contract="***.ISearch" name="SearchController" bindingConfiguration="LargeMessageBinding" />

以及bindingConfiguration="LargeMessageBinding"客户端配置
