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 />
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" ="" contract="DyeService">
16: </endpoint>
17: </service>
18: </services>
19: <bindings>
20: <basicHttpBinding>
21: <binding name="" maxBufferSize="2147483647"
22: maxBufferPoolSize="21474836471"
23: < 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:
15: <endpoint address="" binding="basicHttpBinding" >
16: </endpoint>
17: </service>
18: </services>
19: <bindings>
20: <basicHttpBinding>
21: <binding maxBufferSize="2147483647"
22: maxBufferPoolSize="21474836471" maxReceivedMessageSize="2147483647">
23: </binding>
24: </basicHttpBinding>
25: </bindings>
26: </system.serviceModel>
