Wcf使用Net.Tcp做回调操作

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 void ReturnResult(string strJson)
        {
            Console.WriteLine("start service");
            Monitor.MonitorOnlineService(strJson);
        }

            get
            {
                return OperationContext.Current.GetCallbackChannel<IMonitorService>();
            }
        }
