c# udp发送控制指令

superlxw 2013-07-17 10:19:38

我现在有一个串口采集的程序，是c#的，我现在想做一个程序，通过udp发送指令来控制这个采集的程序，我现在的思路是在这个采集程序里加一个监听端口的线程，请问该怎么加呢，另外就是怎么控制这个程序里的函数，比如最简单的，控制按钮的点击，最后实现的就是有两个程序，在新做的程序里点开始，然后这个采集的程序开始采集，点击结束就停止采集。谢谢各位大侠给点思路

public class SocketListener
{

    private Socket socket = null;
    private int port = 11111;
        /// <summary>

        public void StartListen()
        {
            work = new Thread(new ThreadStart(Start));
            work.IsBackground = true;
            work.Start();
        }
        public void Start()
        {
           try
            {
                IPEndPoint remoteEP = new IPEndPoint(IPAddress.Any, port);
                using (receiveClient = new UdpClient(remoteEP))
                {
                    while (true)
                    {
                        try
                        {
                            //接收
                            byte[] bytes = receiveClient.Receive(ref remoteEP);
                            MessageReceived(bytes);
                            Thread.Sleep(100);
                        }
                        catch(Exception e)
                        {
                            Console.WriteLine("接收udp消息错误,原因：" + e.Message);
                        }
                    }
                }
            }
        }
        /// <summary>
        /// 接收完消息后触发
        /// </summary>
        private void MessageReceived(byte [] bytes)
        {
            if (EvtMessageReceived != null)
            {
                EvtMessageReceived(bytes);
            }
        }
}

接收到消息后通过委托拿到结果，再进行处理，这里你需要定义消息的格式，比如包头+包体：0001|123456 0001为包头，123456为包体


public static void main()
{
    SocketListener sl = new SocketListener();
    sl.EvtMessageReceived += new DltMessage(MessageTransfer);
}
public void MessageTransfer(byte[] bytes)
{
    string msg = Encoding.Default.GetString(bytes);//这里需要注意编码格式，双方编码格式要一致
    string[] message = msg.Split('|');
    if(message[0].Equals("0001"))
     {
        //点击开始按钮...只要拿到了消息就可以为所欲为了
     }
}

请问DltMessage是什么啊，一个新创建的类？是不是要用delegate[/quote] DltMessage是定义的一个委托啊 public delegate void DltMessage(byte bytes)

不好意思，刚刚将UdpClient写错了，下面是更正后的代码：


public class SocketListener
{
    public event DltMessage EvtMessageReceived;// 接收到消息后事件
    private Thread work = null;
    private UdpClient receiveClient = null;
    private int port = 11111;
        /// <summary>
        /// 开始监听
        /// </summary>
        public void StartListen()
        {
            work = new Thread(new ThreadStart(Start));
            work.IsBackground = true;
            work.Start();
        }
        public void Start()
        {
           try
            {
                IPEndPoint remoteEP = new IPEndPoint(IPAddress.Any, port);
                using (receiveClient = new UdpClient(remoteEP))
                {
                    while (true)
                    {
                        try
                        {
                            //接收
                            byte[] bytes = receiveClient.Receive(ref remoteEP);
                            MessageReceived(bytes);
                            Thread.Sleep(100);
                        }
                        catch(Exception e)
                        {
                            Console.WriteLine("接收udp消息错误,原因：" + e.Message);
                        }
                    }
                }
            }
        }
        /// <summary>
        /// 接收完消息后触发
        /// </summary>
        private void MessageReceived(byte [] bytes)
        {
            if (EvtMessageReceived != null)
            {
                EvtMessageReceived(bytes);
            }
        }
}

思路就是：利用多线程循环侦听某个端口以防止界面阻塞，当接收到消息之后根据消息的指令来做相应处理


public class SocketListener
{
    public event DltMessage EvtMessageReceived;// 接收到消息后事件
    private Thread work = null;
    private Socket socket = null;
    private int port = 11111;
        /// <summary>
        /// 开始监听
        /// </summary>
        public void StartListen()
        {
            work = new Thread(new ThreadStart(Start));
            work.IsBackground = true;
            work.Start();
        }
        public void Start()
        {
           try
            {
                IPEndPoint remoteEP = new IPEndPoint(IPAddress.Any, port);
                using (receiveClient = new UdpClient(remoteEP))
                {
                    while (true)
                    {
                        try
                        {
                            //接收
                            byte[] bytes = receiveClient.Receive(ref remoteEP);
                            MessageReceived(bytes);
                            Thread.Sleep(100);
                        }
                        catch(Exception e)
                        {
                            Console.WriteLine("接收udp消息错误,原因：" + e.Message);
                        }
                    }
                }
            }
        }
        /// <summary>
        /// 接收完消息后触发
        /// </summary>
        private void MessageReceived(byte [] bytes)
        {
            if (EvtMessageReceived != null)
            {
                EvtMessageReceived(bytes);
            }
        }
}

接收到消息后通过委托拿到结果，再进行处理，这里你需要定义消息的格式，比如包头+包体：0001|123456 0001为包头，123456为包体


public static void main()
{
    SocketListener sl = new SocketListener();
    sl.EvtMessageReceived += new DltMessage(MessageTransfer);
}
public void MessageTransfer(byte[] bytes)
{
    string msg = Encoding.Default.GetString(bytes);//这里需要注意编码格式，双方编码格式要一致
    string[] message = msg.Split('|');
    if(message[0].Equals("0001"))
     {
        //点击开始按钮...只要拿到了消息就可以为所欲为了
     }
}
