Silverlight和WCF：最大邮件大小

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List变得太大。 似乎当我超过80个项目时，我收到错误：远程服务器返回了意外的响应：（404）Not Found

我认为这是因为List已经变得太大了，就像List有70个物品一样可以正常工作。 但是奇怪的错误信息，对吗？

在配置文件中，我将maxBufferSize更改为它将接受的最高值，但我的列表中仍然不能有超过80个项目。

如何在不拆分对象的情况下传递大对象？

谢谢肖恩，我到底该怎么做？ 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>

这是您提到的服务器配置

---

<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>

Answer 2

有两个配置文件。 silverlight clientconfig将允许您发送更大的消息，但如果您正在使用WCF，则有一个服务器web.config限制接收消息的大小（以防止DDOS攻击）。

Answer 3

在服务器端，更改配置文件以使服务可以接受大消息。

1. 在<system.serviceModel>部分中添加basicHttpBinding配置：

    <?xml version="1.0" encoding="utf-8" ?> <configuration> <system.serviceModel> <bindings> <basicHttpBinding> <binding name="MyBasicHttpBinding" maxReceivedMessageSize="300000000"> <security mode="None"/> <readerQuotas maxStringContentLength="300000000"/> </binding> </basicHttpBinding> </bindings> ....... 

2. 将配置添加到服务绑定。

    <endpoint address="" binding="basicHttpBinding" bindingConfiguration="MyBasicHttpBinding" contract="WcfService1.IService1">
