WCF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

客户端调用的时候加上这一段代码即可：

ServiceData.Service1Client client = new ServiceData.Service1Client();
(client.Endpoint.Binding as BasicHttpBinding).MaxReceivedMessageSize = int.MaxValue;
(client.Endpoint.Binding as BasicHttpBinding).MaxBufferPoolSize = int.MaxValue;
(client.Endpoint.Binding as BasicHttpBinding).MaxBufferSize = int.MaxValue;
