如何添加maxItemsInObjectGraph编程，而无需使用配置文件？ [英] How to add maxItemsInObjectGraph programmatically without using configuration file?

问题描述

我已创建一个这样的的EndpointAddress

 的EndpointAddress地址=新的EndpointAddress（http://example.com/services/OrderService.svc）;
 

但我不能添加行为到这个端点编程。

的行为如下：

 ＆LT;行为＆GT;
  ＆LT; endpointBehaviors＆GT;
    ＆LT;行为NAME =NewBehavior＆GT;
      ＆LT; D​​ataContractSerializer的maxItemsInObjectGraph =6553600/＆GT;
    ＆LT; /行为＆GT;
  ＆LT; / endpointBehaviors＆GT;
＆LT; /行为＆GT;
 

解决方案

在服务器上，您必须将其添加在ServiceBehavior属性：

  [ServiceBehavior（MaxItemsInObjectGraph = int.MaxValue）
 

在客户端，你必须将其应用到端点。在这个例子中，你可以看到如何将它添加到所有终端在你的ChannelFactory：

  VAR厂=新的ChannelFactory＆LT; IInterface＆GT;（...）;
的foreach（OperationDescription运在factory.Endpoint.Contract.Operations）
    {
        变种dataContractBehavior = op.Behaviors.Find＆其中; DataContractSerializerOperationBehavior＆GT;（）;
        如果（dataContractBehavior！= NULL）
        {
            dataContractBehavior.MaxItemsInObjectGraph = int.MaxValue;
        }
    }
 

I have create a EndpointAddress like that

EndpointAddress address = new EndpointAddress("http://example.com/services/OrderService.svc");

But I could not add the Behavior to this Endpoint programmatically.

The behavior is given below.:

<behaviors>
  <endpointBehaviors>
    <behavior name="NewBehavior">
      <dataContractSerializer maxItemsInObjectGraph="6553600" />
    </behavior>
  </endpointBehaviors>
</behaviors>

解决方案

On the server you have to add it in the ServiceBehavior Attribute:

 [ServiceBehavior(MaxItemsInObjectGraph = int.MaxValue)]

On the client you have to apply it to the endpoint. In this example you can see how to add it to all the endpoints in your ChannelFactory:

var factory = new ChannelFactory<IInterface>(...);
foreach (OperationDescription op in factory.Endpoint.Contract.Operations)
    {
        var dataContractBehavior = op.Behaviors.Find<DataContractSerializerOperationBehavior>();
        if (dataContractBehavior != null)
        {
            dataContractBehavior.MaxItemsInObjectGraph = int.MaxValue;
        }
    }
