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.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)

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" />
