model:

using Service.Interface;using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;namespace Models{    public class Client    {        public String Id { get; set; }        public ICallBack CallBack { get; set; }    }}

service:

using Models;using Service.Interface;using System;using System.Collections.Generic;using System.Linq;using System.ServiceModel;using System.Text;using System.Threading.Tasks;namespace Service{    public class NoticeOperator : INoticeOperator    {        private static List<Client> clientList = new List<Client>();        public void Register(string id)        {            Client client = clientList.Find(l => l.Id == id);            if (client != null)            {                clientList.Remove(client);            }            ICallBack callBack = OperationContext.Current.GetCallbackChannel<ICallBack>();            clientList.Add(new Client() { Id = id, CallBack = callBack });            Console.WriteLine("register:" + id);        }        public void UnRegister(string id)        {            Console.WriteLine("unRegister:" + id);            Client client = clientList.Find(c => c.Id == id);            if (client != null)            {                clientList.Remove(client);            }        }        public void SendMessage(string from, string to, string message)        {            Client client = clientList.Find(c => c.Id == to);            if (client != null)            {                String longMessage = String.Format("message from {0}  to {1} at {2} : {3}", from, to, DateTime.Now.ToString("HH:mm:ss"), message);                Console.WriteLine(longMessage);                client.CallBack.Notice(message);            }        }    }}

interface:

using System;using System.Collections.Generic;using System.Linq;using System.ServiceModel;using System.Text;using System.Threading.Tasks;namespace Service.Interface{    public interface ICallBack    {        [OperationContract(IsOneWay = true)]        void Notice(String message);    }}

using System;using System.Collections.Generic;using System.Linq;using System.ServiceModel;using System.Text;using System.Threading.Tasks;namespace Service.Interface{    [ServiceContract(CallbackContract = typeof(ICallBack))]    public interface INoticeOperator    {        [OperationContract]        void Register(String id);        [OperationContract]        void UnRegister(String id);        [OperationContract]        void SendMessage(String from, String to, String message);    }}

挂起服务host：

using Service;using Service.Interface;using System;using System.Collections.Generic;using System.Linq;using System.ServiceModel;using System.ServiceModel.Description;using System.Text;using System.Threading.Tasks;namespace Hosting{    class Program    {        static void Main(string[] args)        {            using (ServiceHost host = new ServiceHost(typeof(NoticeOperator)))            {                NetTcpBinding binding = new NetTcpBinding();                binding.Security.Mode = SecurityMode.None;                host.AddServiceEndpoint(typeof(INoticeOperator), binding, "net.tcp://111.111.1.111:1111/NoticeOperator");                host.Opened += (s, e) => Console.WriteLine("service is running...");                host.Open();                Console.ReadLine();            }        }    }}
