我出现这个问题主要是服务器返回数据量过大引起了，需要客户端服务端都要进行配置；我会说其实有神器的么。。。。（工具=>wcf服务配置编辑器），用工具编辑下，就会完全搞定这个问题，再也不用纠结了
服务端配置（有木有很精简）：
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="NewBinding0" maxBufferPoolSize="2147483647" maxBufferSize="2147483647"
maxReceivedMessageSize="2147483647" />
</basicHttpBinding>
</bindings>
<services>
<service name="Jinher.AMP.SNS.Service.BP.Service.Neighbor">
<endpoint address="http://127.0.0.1:8089/neighbor" binding="basicHttpBinding"
bindingConfiguration="NewBinding0" contract="Jinher.AMP.SNS.Service.BP.IService.INeighbor" />
</service>
</services>
</system.serviceModel>
客户端代码：
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="NewBinding0" maxBufferPoolSize="2147483647" maxBufferSize="2147483647"
maxReceivedMessageSize="2147483647" />
</basicHttpBinding>
</bindings>
<client>
<endpoint address="http://127.0.0.1:8089/neighbor" binding="basicHttpBinding"
bindingConfiguration="NewBinding0" contract="Jinher.AMP.SNS.Service.BP.IService.INeighbor"
name="OnlineUserService" kind="" endpointConfiguration="">
<!--<identity>
<certificateReference storeName="My" storeLocation="LocalMachine"
x509FindType="FindBySubjectDistinguishedName" />
</identity>-->
</endpoint>
</client>
</system.serviceModel>
