将此代码与您的 DataContracts 一起添加到 Contracts 项目。
[ServiceContract(Namespace = "http://schemas.platinumray.com/duplex", SessionMode = SessionMode.Required, CallbackContract = typeof(IService1Callback))]
public interface IService1
{
[OperationContract(IsOneWay = true)]
void GetData();
}
public interface IService1Callback
{
[OperationContract(IsOneWay = true)]
void SetData(Configuration config);
}
创建了服务。
public class Service1 : IService1
{
public void GetData()
{
var x = new Configuration()
{
MyValue = MyEnum.Value1,
CredentialValues = new CustomCredentials { Property1 = "Something", Property2 = "Something else" }
};
OperationContext.Current.GetCallbackChannel<IService1Callback>().SetData(x);
}
}
class Program
{
static void Main(string[] args)
{
using (ServiceHost host = new ServiceHost( typeof(Service1), new Uri[] { new Uri("net.tcp://localhost:6789") }))
{
host.AddServiceEndpoint(typeof(IService1), new NetTcpBinding(), "Service1");
host.Open();
Console.ReadLine();
host.Close();
}
}
}
创建了客户端。
public class CallbackHandler : IService1Callback
{
public void SetData(Configuration config)
{
Console.WriteLine(config.CredentialValues.GetType().Name);
Console.WriteLine(((CustomCredentials)config.CredentialValues).Property1);
Console.WriteLine(((CustomCredentials)config.CredentialValues).Property2);
}
}
class Program
{
static void Main(string[] args)
{
// Setup the client
var callbacks = new CallbackHandler();
var endpoint = new EndpointAddress(new Uri("net.tcp://localhost:6789/Service1"));
using (var factory = new DuplexChannelFactory<IService1>(callbacks, new NetTcpBinding(), endpoint))
{
var client = factory.CreateChannel();
client.GetData();
Console.ReadLine();
factory.Close();
}
}
}
按预期输出以下内容:
CustomCredentials
Something
Something else
所以这实际上在不修改任何数据合同的情况下工作......如果我恢复到双向操作并直接返回Configuration
而不使用回调,则结果相同。
还尝试使凭据抽象,但无法复制您的问题。
我错过了什么吗?
