        public uPLibrary.Networking.M2Mqtt.MqttClient.MqttMsgPublishedEventHandler PubedEventHandler;

        /// <summary>
        /// 向服務器發佈 Topic 時

        public uPLibrary.Networking.M2Mqtt.MqttClient.MqttMsgSubscribedEventHandler SubedEventHandler;

        /// <summary>
        /// 向服務器發佈 Topic 失敗時
        /// </summary>
        public uPLibrary.Networking.M2Mqtt.MqttClient.MqttMsgUnsubscribedEventHandler UnSubedEventHandler;


        /// <summary>
        /// 斷開連接時
        /// </summary>
        public uPLibrary.Networking.M2Mqtt.MqttClient.ConnectionClosedEventHandler ConnectionClosedEventHandler;

使用方法

    public static void TestEvent(object sender, MqttMsgPublishEventArgs e)
        {
            {
                // handle message received
                string topic = e.Topic;
                string message = Encoding.ASCII.GetString(e.Message);
                Console.WriteLine("- - - - - - - - - - ");
                Console.WriteLine("get topic message,Date: " + DateTime.Now.ToLongTimeString());
                Console.WriteLine("topic: " + topic);
                Console.WriteLine("get messgae :\n" + message);
        }

            client.PubPropertyEventHandler += TestEvent;
