ProtocolException : 已超过传入消息(65536)的最大消息大小配额。

SilverLight调用WCF，提交的是一个List<Linq2SqlEntity>；当List中数据量不大的时候，不会报错；当数据量稍微大一点儿，就会出现这个错误。发生了 System.ServiceModel.ProtocolException
  Message=已超过传入消息(65536)的最大消息大小配额。若要增加配额，请使用相应绑定元素上的 MaxReceivedMessageSize 属性。
  Source=System.ServiceModel
  StackTrace:
  在 System.ServiceModel.Channels.HttpInput.ThrowHttpProtocolException(String message, HttpStatusCode statusCode, String statusDescription)

 

    费了牛劲在网上搜了一通，有的说是要修改behavior的maxItemsInObjectGraph，有的说要修改binding的maxBufferSize/maxReceivedMessageSize，有的说要增加readerQuotas，有的是endpoint没有与自定义binding配置节关联起来，有的说要客户端和服务器端都要改(我的应用中，接受数据的是服务器端，客户端负责提交，所以应该不关客户端的事儿)。。。然后把server端的配置文件调整成下面这样：

   1: <system.serviceModel>

   2:   <behaviors>

   3:     <serviceBehaviors>

   4:       <behavior name="MessageHeaderOperationBehaviourAuthenticationBehavior">

   5:         <dataContractSerializer maxItemsInObjectGraph="2147483647"/>

   6:         <serviceMetadata httpGetEnabled="true"/>

   7:         <serviceDebug includeExceptionDetailInFaults="true"/>

   8:       </behavior>

   9:     </serviceBehaviors>

  10:   </behaviors>

  11:   <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true"/>

  12:   <services>

  13:     <service behaviorConfiguration="MessageHeaderOperationBehaviourAuthenticationBehavior"

  14:              name="MessageHeaderOperationBehaviourAuthentication">

  15:       <endpoint address="" binding="basicHttpBinding" bindingConfiguration="LargeSize" contract="DyeService">

  16:       </endpoint>

  17:     </service>

  18:   </services>

  19:   <bindings>

  20:     <basicHttpBinding>

  21:       <binding name="LargeSize"  maxBufferSize="2147483647"

  22:                maxBufferPoolSize="21474836471" maxReceivedMessageSize="2147483647">

  23:         <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647"

  24:                       maxArrayLength="2147483647" maxBytesPerRead="2147483647"

  25:                       maxNameTableCharCount="2147483647" />

  26:         <security mode="None" />

  27:       </binding>

  28:     </basicHttpBinding>

  29:   </bindings>

  30: </system.serviceModel>

       但是问题依旧。最后在stackoverflow找到了正解：WCF Error - unexpected response: (400) Bad Request.，里面链接到了另一篇帖子：Cannot get the MaxReceivedMessageSize higher than (65536)

 

      解决办法就是：配置文件中，service 的name属性必须与服务的类型全名称保持一致，才能应用上自定义的配置节。

      按着这个方法，调整之后的配置文件如下所示（删掉了其他无关的maxItemsInObjectGraph、readerQuotas等）：

   1:  

   2:   <system.serviceModel>

   3:     <behaviors>

   4:       <serviceBehaviors>

   5:         <behavior name="MessageHeaderOperationBehaviourAuthenticationBehavior">

   6:           <serviceMetadata httpGetEnabled="true"/>

   7:           <serviceDebug includeExceptionDetailInFaults="true"/>

   8:         </behavior>

   9:       </serviceBehaviors>

  10:     </behaviors>

  11:     <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true"/>

  12:     <services>

  13:       <service behaviorConfiguration="MessageHeaderOperationBehaviourAuthenticationBehavior"

  14:                name="NameSpace.DyeService">

  15:         <endpoint address="" binding="basicHttpBinding" bindingConfiguration="LargeSize" contract="NameSpace.DyeService">

  16:         </endpoint>

  17:       </service>

  18:     </services>

  19:     <bindings>

  20:       <basicHttpBinding>

  21:         <binding name="LargeSize"  maxBufferSize="2147483647"

  22:                  maxBufferPoolSize="21474836471" maxReceivedMessageSize="2147483647">

  23:         </binding>

  24:       </basicHttpBinding>

  25:     </bindings>

  26:   </system.serviceModel>
