契约:
[ServiceContract(Namespace = "http://Microsoft.ServiceModel.Samples", SessionMode = SessionMode.Required, CallbackContract = typeof(ITransferCallback))] 如果要使用回调,必须加上这句话 public interface IMonitorService { [OperationContract(IsOneWay = true)] void MonitorOnlineService(string strJson); }
[ServiceContract(CallbackContract = typeof(IMonitorService))] public interface ITransferCallback { [OperationContract(IsOneWay = true)] void ReturnResult(string strJson); }

接口实现
public class TransferCallback : ITransferCallback { public void ReturnResult(string strJson) { Console.WriteLine("start service"); Monitor.MonitorOnlineService(strJson); } private IMonitorService Monitor { get { return OperationContext.Current.GetCallbackChannel<IMonitorService>(); } } }

启用服务
class Program { static void Main(string[] args) { using (ServiceHost host = new ServiceHost(typeof(DataTransferCallback))) { ServiceMetadataBehavior smb = host.Description.Behaviors.Find<ServiceMetadataBehavior>(); if (smb == null) host.Description.Behaviors.Add(new ServiceMetadataBehavior()); //暴露出元数据,以便能够让SvcUtil.exe自动生成配置文件 host.AddServiceEndpoint(typeof(IMetadataExchange), MetadataExchangeBindings.CreateMexTcpBinding(), "mex"); //开启服务 host.Open(); Console.WriteLine("Service listen begin to listen..."); Console.WriteLine("press any key to teriminate..."); Console.ReadKey(); host.Abort(); host.Close(); } } }

调用服务 new ChannelFactory<IDataTransferCallback>("NetTcpBinding_ITransferCallback").CreateChannel().ReturnResult("Hello");

这样服务就可以循环交互了,直到一个服务停止为止
