我在WCF调用上收到以下错误:

对象图中可序列化或反序列化的最大项数为“65536”

我已经阅读了大量的论坛帖子,其中许多人提到修改app.config和web.config以指定允许更大对象图的新行为 . 我已经这样做了,这就是我在这些文件中所拥有的:

App.Config on the WPF project:

<system.serviceModel>
<behaviors>
  <serviceBehaviors>
    <behavior name="">
      <serviceMetadata httpGetEnabled="false" />
      <serviceDebug includeExceptionDetailInFaults="false" />
    </behavior>
  </serviceBehaviors>
  <endpointBehaviors>
    <behavior name="">
      <dataContractSerializer maxItemsInObjectGraph="2147483646"/>
    </behavior>

  </endpointBehaviors>

</behaviors>

<services>
  <service name="digiPM.Shell.LogOutPMSEMRService.PMSEMRLogOutService">
    <!--<endpoint address="" binding="basicHttpBinding" contract="digiPM.Shell.LogOutPMSEMRService.IPMSEMRLogOutService">
      <identity>
        <dns value="localhost" />
      </identity>
    </endpoint>
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
    <host>
      <baseAddresses>
        <add baseAddress="http://localhost:8732/Design_Time_Addresses/digiPM.Shell.LogOutPMSEMRService/PMSEMRLogOutService/" />
      </baseAddresses>
    </host>-->
    <endpoint address="" binding="netTcpBinding" name="NetTcpBindingEndpoint" contract="digiPM.Shell.LogOutPMSEMRService.IPMSEMRLogOutService">
      <identity>
        <dns value="localhost" />
      </identity>
    </endpoint>
    <endpoint address="mex" binding="mexTcpBinding" bindingConfiguration="" name="MexTcpBidingEndpoint" contract="IMetadataExchange" />
    <host>
      <baseAddresses>
        <add baseAddress="net.tcp://localhost:8732/Design_Time_Addresses/digiPM.Shell.LogOutPMSEMRService/PMSEMRLogOutService/" />
      </baseAddresses>
    </host>
  </service>
</services>

<!--binding info - removed this for the sake of readability for this post -->

web.config on the service project:

<system.serviceModel>

<bindings>
  <wsHttpBinding>
      <binding name="WSHttpBinding_Services" closeTimeout="01:10:00" openTimeout="01:10:00" receiveTimeout="01:10:00" sendTimeout="01:10:00" bypassProxyOnLocal="false"

          <reliableSession ordered="true" inactivityTimeout="01:10:00" enabled="false" />

          <security mode="None">

  </service>

 <!--<more services defined with same configuration as above..>-->

  </services>


</system.serviceModel>

然而,这没有帮助 . 请注意,APP.CONFIG中引用的服务不是我遇到的服务问题 .

我也尝试了以下内容:

  • 将这些属性添加到服务实现:[DataContract(IsReference = true)],[ServiceBehavior(AddressFilterMode = AddressFilterMode.Any,MaxItemsInObjectGraph = 2147483646)]

  • 编写了一个自定义DataContractSerializerOperationBehavior类,它设置了MaximumObjectsInGraph和IsReference行为 . 还添加了自定义属性以应用此服务实现 . 为了杂乱,我没有发布代码,但可以添加它,如果有人认为这将是有益的 .

思考?想法?我从哪里去?

提前致谢!

    我刚刚意识到你的WPF配置文件不对 . 所以,我删除了所有评论,因为他们假设有效的WCF配置 . 您的WPF配置文件不正确...它需要说“客户端”而不是服务...您是否在Visual Studio中使用“添加服务引用”?如果是这样,它应该为您创建正确的配置文件 .

    否则,请参阅MSDN以获取WPF项目中客户端配置文件的正确格式 .

    配置以下值为我解决了问题 .

    客户端配置:

    <system.serviceModel>
    <bindings>
    <basicHttpBinding>
      <binding name="BasicHttpBinding_IManagementService" closeTimeout="00:01:00"
        openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
        allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
        maxBufferSize="2147483647" maxBufferPoolSize="524288" maxReceivedMessageSize="2147483647"
        messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
        useDefaultWebProxy="true">
        <readerQuotas maxDepth="128" maxStringContentLength="2147483647"
          maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" />
        <security mode="None">
          <transport clientCredentialType="None" proxyCredentialType="None"
            realm="" />
          <message clientCredentialType="UserName" algorithmSuite="Default" />
        </security>
      </binding>
    </basicHttpBinding>
    </bindings>
    <client>
    <endpoint address="http://XXXX/ManagementService.svc"
      binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IManagementService"
      contract="ManagementServiceReference.IManagementService"
      name="BasicHttpBinding_IManagementService" behaviorConfiguration="ManagementServiceBehaviour"/>
    </client>
    <behaviors>
    <endpointBehaviors>
      <behavior name="ManagementServiceBehaviour">
        <dataContractSerializer maxItemsInObjectGraph="2147483647"/>
      </behavior>
    </endpointBehaviors>
    </behaviors>
    

    服务器配置:

    <system.serviceModel>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
    <behaviors>
    <serviceBehaviors>
      <behavior name="ManagementServiceBehaviour">
        <serviceDebug includeExceptionDetailInFaults="true" />

      </behavior>
      <behavior name="">
        <serviceMetadata httpGetEnabled="true" />
        <serviceDebug includeExceptionDetailInFaults="false" />
      </behavior>
    </serviceBehaviors>
    </behaviors>
    <bindings>

      <binding name="BasicHttpBinding" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" closeTimeout="01:50:00" openTimeout="01:50:00" sendTimeout="01:50:00" receiveTimeout="01:50:00" >
        <readerQuotas maxDepth="128" maxStringContentLength="8388608" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" />
      </binding>
    </basicHttpBinding>

    <services>
    <service behaviorConfiguration="ManagementServiceBehaviour" name="BusinessLogic.Facade.EntityFacade.Services.ManagementService">

        </identity>
      </endpoint>
    </service>

    您是否尝试过缓冲区和最大收到的邮件大小?

    maxBufferSize="6553600" maxBufferPoolSize="52428800" maxReceivedMessageSize="6553600"

    注意“dataContractSerializer”元素 . 在我的情况下,我得到了提到的错误,直到我把这个元素作为父元素“行为”的第一项 . 至少在客户端确实如此 .

    您将在查询中返回一个通用列表或大小超过65536的数组 . 使用select top 60000或不添加超过60k的元素将解决您的问题 .
