WCF中如何修改MaxItemsInObjectGraph的限制

在WCF/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.configmaxReceivedMessageSize,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)

生成XML如下,其中红色部分是被修改的部分:
<behavior name="NewBehavior"> 
    <dataContractSerializer maxItemsInObjectGraph="65536000" /> 
</behavior

...

<endpoint address="http://localhost:3511/Service1.asmx" behaviorConfiguration="NewBehavior
                binding="basicHttpBinding" bindingConfiguration="Service1Soap" 
                contract="WebSvc.Service1Soap" name="Service1Soap" />
