c# - 银光和 WCF : Max message size

Question

当我使用 WCF 从我的 silverlight 应用程序中传递一个对象列表时，一切正常，直到列表变得太大。似乎当我超过 80 个项目时，我得到了错误:远程服务器返回意外响应:(404) 未找到

我假设这是因为列表变得太大了，因为当列表有 70 个项目时一切正常。奇怪的错误消息，对吧？

在配置文件中，我将 maxBufferSize 更改为它可以接受的最大值，但我的列表中的项目仍然不能超过 80 个。

如何在不拆分大物体的情况下传递大物体？

谢谢 Shawn，那么我到底应该在哪里做呢？这是我的 ServiceReferences.ClientConfig

<configuration>
<system.serviceModel>
    <client>
      <!--"http://sy01911.fw.gsjbw.com/WcfService1/Service1.svc"-->
      <endpoint address="http://localhost/WcfService1/Service1.svc"
            binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IService11"
            contract="SilverlightApplication1.ServiceReference1.IService1"
            name="BasicHttpBinding_IService1" />
    </client>
    <bindings>
        <basicHttpBinding>
            <binding name="BasicHttpBinding_IService1" maxBufferSize="655360000"
                maxReceivedMessageSize="655360000">
                <security mode="None" />
            </binding>
            <binding name="BasicHttpBinding_IService11" maxBufferSize="655360000"
                maxReceivedMessageSize="655360000">
                <security mode="None" />
            </binding>
        </basicHttpBinding>
    </bindings>
</system.serviceModel>

这是你提到的服务器配置

<services>
  <service name="WcfService1.Service1" behaviorConfiguration="WcfService1.Service1Behavior" >
    <!-- Service Endpoints -->
    <endpoint address="" binding="basicHttpBinding" contract="WcfService1.IService1" >
      <!-- 
          Upon deployment, the following identity element should be removed or replaced to reflect the 
          identity under which the deployed service runs.  If removed, WCF will infer an appropriate identity 
          automatically.
      -->
      <identity>
        <dns value="localhost"/>
      </identity>
    </endpoint>
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
  </service>
</services>
<behaviors>
  <serviceBehaviors>
    <behavior name="WcfService1.Service1Behavior">
      <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
      <serviceMetadata httpGetEnabled="true"/>
      <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
      <serviceDebug includeExceptionDetailInFaults="true"/>
    </behavior>
  </serviceBehaviors>
</behaviors>

Answer 1

如果您从 WCF 发送大量项目，还要确保 maxItemsInObjectGraph 是一个相对较高的数字

<behaviors>
   <serviceBehaviors>
      <behavior name="YourBahvior">
         <dataContractSerializer maxItemsInObjectGraph="6553600"/>
      </behavior>
   </serviceBehaviors>
</behaviors>
