Silverlight在调用wcf时传输数据过大返回Not Found的解决办法

默认情况下，silverlight在调用wcf时，如果传递的数据中XML的Element的内容长度大于8192字节，即8k，会提示Not Found错误。

调用含有byte[]的方法时，内容长度大于16k时，也会出现Not Found错误。

解决方法如下：

1、wcf服务端修改web.config 如下:

<system.serviceModel>

<behaviors>

<serviceBehaviors>

<!--注:name=随意命名，但要与service的behaviorConfiguration值对应-->

<behavior name="AAAAA">

<serviceMetadata httpGetEnabled="true" />

<serviceDebug includeExceptionDetailInFaults="false" />

<dataContractSerializer maxItemsInObjectGraph="2147483647"/>

</behavior>

</serviceBehaviors>

</behaviors>

<services>

<!--注1:此处的name值不能随便修改，命名格式为：完全命名空间+类名 -->

<!--注2:此处的behaviorConfiguration值要与behavior的name值对应-->

<service name="SLFileUpload.Web.FileService" behaviorConfiguration="AAAAA" >

<!--注1:此处的contract值不能随便修改，命名格式为：完全命名空间+接口名 -->

<!--注2:此处的bindingConfiguration值要与binding中的name值对应-->

<endpoint contract="SLFileUpload.Web.IFileService" binding="basicHttpBinding" bindingConfiguration="BBBBB" address="" >

</endpoint>

<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />

</service>

</services>

<bindings>

<basicHttpBinding>

<!--name=随意命名，但要与service的bindingConfiguration值对应 -->

<binding name="BBBBB" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">

<readerQuotas maxStringContentLength="2147483647" maxArrayLength="2147483647"/>

<security mode="None"></security>

</binding>

</basicHttpBinding>

</bindings>

<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />

</system.serviceModel>

2，Silverlight端

<bindings>

<basicHttpBinding>

<binding name="BasicHttpBinding_IFileService" maxBufferSize="2147483647"

maxReceivedMessageSize="2147483647">

<security mode="None" />

</binding>

</basicHttpBinding>

</bindings>
