public PublishPropertyEventHandler PubPropertyEventHandler;
/// <summary>
/// 服务调用
/// </summary>
public PublishServiceEventHandler PubServiceEventHandler;
/// <summary>
/// 收到其它Topic时触发
/// </summary>
public PublishCommonEventHandler PubCommonEventHandler;
/// <summary>

public uPLibrary.Networking.M2Mqtt.MqttClient.MqttMsgPublishedEventHandler PubedEventHandler;
/// <summary>
/// 向服务器发布 Topic 时

/// <summary>
/// 断开连接时

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;
