在我们用WCF传输数据的时候，如果启用默认配置，传输的数据量过大，经常会出这个错误。
WCF包含服务端与客户端，所以这个错误可能出现在服务端返回数据给客户端，或客户端传数据给服务端时。
1. 服务端返回数据给客户端报错
在客户端配置文件中，主要是配置maxReceivedMessageSize
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="ServiceProxyBinding" closeTimeout="00:10:00" receiveTimeout="00:10:00"
sendTimeout="00:10:00" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">
<readerQuotas maxStringContentLength="134217728" />
</binding>
</basicHttpBinding>
</bindings>
<client>
<endpoint address="http://localhost:5239/AHMTService/PartService.svc"
binding="basicHttpBinding" bindingConfiguration="ServiceProxyBinding"
contract="UniCloud.ServiceContracts.IPartService" name="IPartService" />
</client>
</system.serviceModel>
2 客户端传数据给服务端报错
修改服务端web.config,主要也是配置maxReceivedMessageSize
<system.serviceModel>
<services>
<!--DecodeService 服务端配置 增加接收文件大小-->
<service name="UniCloud.Services.DecodeService" behaviorConfiguration="MyServiceBehaviour" >
<endpoint address="" binding="basicHttpBinding" bindingConfiguration="MyServiceBinding" contract="UniCloud.ServiceContracts.IDecodeService">
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
<host>
<baseAddresses>
<add baseAddress="http://localhost:5239/AHMTService"/>
</baseAddresses>
</host>
</service>
</services>
<bindings>
<basicHttpBinding>
<binding name="MyServiceBinding" closeTimeout="00:10:00" receiveTimeout="00:20:00" sendTimeout="00:20:00"
maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">
<security mode="None"></security>
</binding>
</basicHttpBinding>
</bindings>
<behaviors>
<serviceBehaviors>
<behavior name="MyServiceBehaviour">
<!-- 为避免泄漏元数据信息，请在部署前将以下值设置为 false -->
<serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
<!-- 要接收故障异常详细信息以进行调试，请将以下值设置为 true。在部署前设置为 false 以避免泄漏异常信息 -->
<serviceDebug includeExceptionDetailInFaults="true" />
<dataContractSerializer maxItemsInObjectGraph="2147483647"/>
</behavior>
</serviceBehaviors>
</behaviors>
<protocolMapping>
<add binding="basicHttpsBinding" scheme="https" />
</protocolMapping>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
</system.serviceModel>
其实要修改所有的服务，不管是服务端还是客户端，Binding那边增加一个没有设置名字的默认配置就OK了
<binding closeTimeout="00:10:00" receiveTimeout="00:20:00" sendTimeout="00:20:00" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">
