.net 大型 WCF Web 服务请求因 (400) HTTP 错误请求而失败

我遇到过这个明显常见的问题，一直无法解决.

If I call my WCF web service with a relatively small number of items in an array parameter (I've tested up to 50), everything is fine.个

However if I call the web service with 500 items, I get the Bad Request error.

有趣的是，我在服务器上运行了Wireshark，看起来请求甚至没有到达服务器-400错误是在客户端生成的.

The exception is:

System.ServiceModel.ProtocolException:远程服务器返回意外响应:(400)错误请求.-&gt；System.Net.WebException:远程服务器返回错误:(400)请求错误.

The 100 section of my client config file is:

 <system.serviceModel>
    <bindings>
        <wsHttpBinding>
            <binding name="WSHttpBinding_IMyService" closeTimeout="00:01:00"
                openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
                bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard"

                    <message clientCredentialType="Windows" negotiateServiceCredential="true"
                        establishSecurityContext="true" />

        </wsHttpBinding>
    </bindings>
    <client>
        <endpoint address="http://serviceserver/MyService.svc"

            contract="SmsSendingService.IMyService" name="WSHttpBinding_IMyService" />
    </client>
</system.serviceModel>

On the server side, my web.config file has the following 100 section:

<system.serviceModel>
    <services>
        <service name="MyService.MyService" behaviorConfiguration="MyService.MyServiceBehaviour" >
            <endpoint address="" binding="wsHttpBinding" bindingConfiguration="MyService.MyServiceBinding" contract="MyService.IMyService">
            </endpoint>
            <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
        </service>
    </services>
    <bindings>
      <wsHttpBinding>
        <binding name="MyService.MyServiceBinding">
          <security mode="None"></security>
        </binding>
      </wsHttpBinding>
    </bindings>
    <behaviors>
        <serviceBehaviors>
            <behavior name="MyService.MyServiceBehaviour">
                <!-- 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>
</system.serviceModel>

我有looked at个fairly large个number个answers到this question个no success个.

有人能帮我吗？
