WCF返回长List出错："wcf 基础连接已经关闭: 连接被意外关闭"

返回长对象列表，开始出现问题是
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。
配置文件修改MaxReceivedMessageSize后解决。
但是当返回列表中对象超过一定数量（2000）后，出现错误：
未处理 System.ServiceModel.CommunicationException

怎么解决

3 个解决方案

#1

<binding name="basicHttpBinding" maxBufferSize="2048000" maxBufferPoolSize="1048576" maxReceivedMessageSize="2048000">
...
</binding>

把上面的值去掉，或者改大些。在web.config或者app.config里面

#2

{System.ServiceModel.CommunicationException}
"   位于 System.ServiceModel.AsyncResult.End[TAsyncResult](IAsyncResult result)\r\n   位于 System.ServiceModel.Channels.ServiceChannel.SendAsyncResult.End(SendAsyncResult result)\r\n   位于 System.ServiceModel.Channels.ServiceChannel.EndCall(String action, Object[] outs, IAsyncResult result)\r\n   位于 System.ServiceModel.ClientBase`1.ChannelBase`1.EndInvoke(String methodName, Object[] args, IAsyncResult result)\r\n   位于 YautaSoft.SmartEMS.Silverlight.SmartEMSService.ServiceClient.ServiceClientChannel.EndGetAllUsers(IAsyncResult result)\r\n   位于 YautaSoft.SmartEMS.Silverlight.SmartEMSService.ServiceClient.YautaSoft.SmartEMS.Silverlight.SmartEMSService.Service.EndGetAllUsers(IAsyncResult result)\r\n   位于 YautaSoft.SmartEMS.Silverlight.SmartEMSService.ServiceClient.OnEndGetAllUsers(IAsyncResult result)\r\n   位于 System.ServiceModel.ClientBase`1.OnAsyncCallCompleted(IAsyncResult result)"

我觉得有可能是List的问题，但是奇怪的是我这里一会儿可以一会儿不可以，把我都搞晕了

#3

我也遇到过，一般情况下士数据访问的错误
