如何在不使用配置文件的情况下以编程方式添加maxItemsInObjectGraph？

Question

我已经创建了类似的端点地址

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

但是我无法以编程方式将此行为添加到此端点。

行为如下：

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

Answer 1

在服务器上，您必须将其添加到ServiceBehavior属性中：

 [ServiceBehavior(MaxItemsInObjectGraph = int.MaxValue)]

在客户端上，您必须将其应用于端点。在此示例中，您可以看到如何将其添加到ChannelFactory中的所有端点：

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;
        }
    }

Answer 2

在服务器端，您还可以：

ServiceHost host = new ServiceHost();
ServiceBehaviorAttribute sba = host .Description.Behaviors.Find<ServiceBehaviorAttribute>();
            if (sba == null)
            {
                sba = new ServiceBehaviorAttribute();
                sba.MaxItemsInObjectGraph = int.MaxValue;
                host.Description.Behaviors.Add(sba);
}

Answer 3

替代方案：((ServiceBehaviorAttribute) host.Description.Behaviors[typeof(ServiceBehaviorAttribute)]).MaxItemsInObjectGraph = int.MaxValue;
