若要增加配额，请使用相应绑定元素上的 MaxReceivedMessageSize 属性

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：

WebService代码

Client端代码

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)





因为关联配置节点比较多，这个时候就得动用 WCF Service Configuration Edition 来修改了。





(1) 打开app.config 修改 Advanced 节点，为 Endpoint Behaviors 添加一个新的Behavior：“dataContractSerializer”, 修改该属性“MaxItemsInObjectGraph”的值









(2) 修改Client节点的Endpoints的Service1Soap的BehaviorConfiguration关联上刚才增加的NewBehavior





(3) 保存

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" />
