NetMq学习--发布订阅（一）

基于NeqMq 4.0.0-rc5版本

发布端：

 using (var publisher = new PublisherSocket())

            {

                publisher.Bind("tcp://*:5556");

                var rng = new Random();

                while (true)

                {

                    Stopwatch sw = new Stopwatch();

                    sw.Start();

                    Console.WriteLine();

                    Console.WriteLine();

                    var list = GetList<Messages>(sql);

                    var wards = list.GroupBy(s => s.所属病区).Select(s => s.Key).ToList();

                    foreach (var item in wards)

                    {

                        publisher.SendMoreFrame(item);//发送信封标识，用于消息过滤

                        var msg = string.Join(";", list.FindAll(s => s.所属病区 == item).Select(s => s.Message));

                        publisher.SendFrame(msg);

                        //Console.WriteLine($"{item}");

                    }

                    //int zipcode = rng.Next(0, 99999);

                    //int temperature = rng.Next(-80, 135);

                    //int relhumidity = rng.Next(0, 90);

                    //Console.WriteLine($"{zipcode} {temperature} {relhumidity}");

                    //publisher.SendMoreFrame("AAA");//发送信封标识，用于消息过滤

                    //publisher.SendFrame($"{zipcode} {temperature} {relhumidity}");

                    sw.Stop();

                    Console.WriteLine("用时:" + sw.ElapsedMilliseconds);

                    Thread.Sleep();

                }

            }

订阅端：

  using (var subscriber = new SubscriberSocket())

            {

                subscriber.Connect("tcp://172.16.131.222:5556");

                //subscriber.Subscribe(zipToSubscribeTo.ToString(CultureInfo.InvariantCulture));

                //订阅多个信封  执行多次Subscribe即可

                //订阅全部消息   SubscribeToAnyTopic();方法  或 Subscribe("")内参数传空

                subscriber.Subscribe(wards[r.Next(, wards.Count - )]);//订阅消息，根据消息信封过滤消息

                //subscriber.Subscribe("11384");

                //subscriber.SubscribeToAnyTopic();

                subscriber.Subscribe(wards[r.Next(, wards.Count - )]);

                subscriber.Subscribe(wards[r.Next(, wards.Count - )]);

                while (true)

                {

                    //subscriber.SkipFrame();//跳过消息信封，只接收消息内容

                    string results = subscriber.ReceiveFrameString();

                    Console.WriteLine(results);

                }

            }
