        {
            {
                // 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;
