如何修改MaxItemsInObjectGraph的限制

在WebService中,如果返回值过大,比如Array,List,DataSet等达到一定数量级的话,可能引发下面的异常:
1.受信Message Quota Size超过65536 (System.ServiceModel.CommunicationException)

解决方法:修改客户端配置文件app.config 的 maxReceivedMessageSize,maxBufferSize 两个属性。

但是,数量级继续增大,还会遇到新的问题:
2.MaxItemsInObjectGraph Quta Size超过65536(InnerException:System.Runtime.SerializationException)

解决方法(注意红色和加粗部分):
