在 WCF 客户端中设置 ServiceBehaviorAttribute？

Question

我需要通过代码设置参数

ServiceBehaviorAttribute

private static BasicHttpBinding getBinding()//BasicHttpBinding getBinding()
{

    //WSHttpBinding binding = new WSHttpBinding();
    //WSHttpBinding binding = new WSHttpBinding();
    BasicHttpBinding binding = new BasicHttpBinding(BasicHttpSecurityMode.None);

    binding.TextEncoding = System.Text.Encoding.UTF8;
    binding.ReaderQuotas.MaxArrayLength = int.MaxValue;

    binding.ReceiveTimeout = new TimeSpan(8, 0, 0);
    binding.SendTimeout = new TimeSpan(8, 0, 0);

    binding.MaxReceivedMessageSize = int.MaxValue;
    binding.MaxBufferSize = int.MaxValue;
    binding.MaxBufferPoolSize = int.MaxValue;


    binding.ReaderQuotas.MaxDepth = 64;
    binding.ReaderQuotas.MaxArrayLength = int.MaxValue;
    binding.ReaderQuotas.MaxStringContentLength = int.MaxValue;

    return binding;
}


private static EndpointAddress getEndPoint()
{
    EndpointAddress endPoint = new EndpointAddress(HTTP_SERVER);
    return endPoint;
}


ConnectionToServer = new ConnectionToServer (getBinding(), new EndpointAddress(HTTP_SERVER));

热插入ConnectionToServer这个代码？？？

ServiceBehaviorAttribute sba = new ServiceBehaviorAttribute();
sba.MaxItemsInObjectGraph = int.MaxValue;

一件事是端点配置（即您发布的代码），另一件事完全不同的是服务行为。

要设置 SBA.MaxItemsInObjectGraph，您需要在服务合同的执行行为中指定它，这是通过 WCF 服务中的 ServiceBehaviorAttribute 完成的（而不是您的代码所暗示的客户端）。

即：

[ServiceBehavior(
    InstanceContextMode = InstanceContextMode.Single,
    ConcurrencyMode = ConcurrencyMode.Reentrant,
    MaxItemsInObjectGraph = 34)]
public class WcfService : IDuplexService
{
    //service implementation goes here
}

这是在 ChannelFactory 上设置 MaxItemsInObjectGraph 的方法：

        DuplexChannelFactory<IService> cf = new DuplexChannelFactory<IService>(typeof(ServiceCallback), Server.ServerBinding(), ep);

        foreach (OperationDescription operation in cf.Endpoint.Contract.Operations)
        {
            var dc = operation.Behaviors.Find<DataContractSerializerOperationBehavior>();
            if (dc != null)
            {
                dc.MaxItemsInObjectGraph = int.MaxValue;
            }
        }
