wcf - System.ServiceModel.CommunicationException - 在大消息大小上

Question

我在客户端应用程序上遇到了这个异常，不知道如何解决这个问题。
当返回的数据(价格列表)超过 15MB，但适用于小于 15MB 的消息时，我遇到了这个异常。

错误消息:

接收对“http://localhost:8782/CMDService”的 HTTP 响应时出错。这可能是由于服务端点绑定(bind)未使用 HTTP 协议(protocol)。这也可能是由于服务器中止了 HTTP 请求上下文(可能是由于服务关闭)。有关更多详细信息，请参阅服务器日志。

对服务的跟踪未报告任何异常

服务端和客户端的配置相同

任何帮助将非常感激。谢谢

简单地说，在行为中，您有 serviceBehavior 和 endpointBehavior。你应该这样写:

<behaviors>
    <endpointBehaviors>
      <behavior>
        <dataContractSerializer maxItemsInObjectGraph="10000000"/>
      </behavior>
    </endpointBehaviors>
    <serviceBehaviors>
      <behavior>
        <dataContractSerializer maxItemsInObjectGraph="2147483647"/>
        <serviceMetadata httpGetEnabled="true" />            
        <serviceDebug includeExceptionDetailInFaults="true" />
      </behavior>
    </serviceBehaviors>
  </behaviors>

希望有帮助!
