Question

我在客户端应用程序上遇到此异常，不知道如何通过它。返回的数据（价格清单）超过15MB时遇到此异常，但适用于小于15MB的邮件大小。

错误消息：

接收到“http://localhost:8782/CMDService”的HTTP响应时发生错误。这可能是由于服务端点绑定不使用HTTP协议。这也可能是由于服务器中止HTTP请求上下文（可能是由于服务关闭）。有关详细信息，请参阅服务器日志。

Answer 1

简要介绍一下您拥有serviceBehavior和endpointBehavior的行为。你应该写这样的东西：

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

希望有所帮助！

如果您的服务由ASP.NET托管，则可能必须增加ASP.NET的最大上载大小：

  <system.web>
    <httpRuntime maxRequestLength="2147483647" />
  </system.web>
