c# socket 多线程问题

[epngllh]

问题是这样的,我在写一个socket服务端的应答程序,使用同步操作方式,程序打开,开始侦听,代码如下:

//程序开始运行,监听话机,启用了多线程.
                    serverSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
                    IPAddress serverIP = IPAddress.Parse(ipaddressnow);
                    IPEndPoint serverhost = new IPEndPoint(serverIP, Convert.ToInt32(ipportnow));
                    serverSocket.Bind(serverhost);
                    serverSocket.Listen(200);
                    
                    while(true)
                    {
                        try
                        {
                            //在套接字上接收接入的连接
                            Socket s = serverSocket.Accept();
                            clientSocket = s;
                            ListenClient lc = new ListenClient(clientSocket);
                            clientThread = new Thread(new ThreadStart(lc.ServerThreadProc));
                            clientThread.Start();
                        }
                        catch (Exception ex)
                        {
                            MessageBox.Show("listening Error: " + ex.Message);
                        }
                    }

代码里,把接收客户端并处理客户端的信息全部放在ListenClient类里进行处理.

现在的问题是,我想把处理的一些信息发回到主线程的显示框里显示出来.我知道要用委托,但不知道在类里面怎么调用.请高手帮忙..

接分

ListenClient类：
public delegate void SomeMessageEventHandler(string strMsg);
public event SomeMessageEventHandler SomeMessageEvent = null;

在需要触发事件的方法中:
if(SomeMessageEvent != null)
{
SomeMessageEvent(strMessage);//需要传递的消息，可以是对象，或者其他参数，不必一定是字符串，看委托如何声明
}

主线程：
ListenClient lc = new ListenClient(clientSocket);
lc.SomeMessageEvent += new SomeMessageEventHandler(lc_SomeMessageEvent);

处理方法：
private void lc_SomeMessageEvent(string strMsg)
{
//处理消息
}

class Sock
{

private Socket m_sock;
private IPEndPoint m_serverEndPoint;

public Sock(int localPort, int servPort, string servIPAddr)
{
IPAddress localAddress = IPAddress.Parse("127.0.0.1");
IPEndPoint localEndPoint = new IPEndPoint(localAddress, localPort);

IPAddress serverAddress = IPAddress.Parse(servIPAddr);
m_serverEndPoint = new IPEndPoint(serverAddress, servPort);

m_sock = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
m_sock.Bind(localEndPoint);
}

~Sock()
{
if (m_sock != null)
{
m_sock.Shutdown(SocketShutdown.Both);
m_sock.Close();
}
}

public int SendData(String msg)
{
Byte[] buf = Encoding.ASCII.GetBytes(msg.ToCharArray());
return m_sock.SendTo(buf, m_serverEndPoint);
}

public int ReceiveData(ref String data)
{
Byte[] buf;
buf = new Byte[4096];
EndPoint servPort = (EndPoint)m_serverEndPoint;
int len = m_sock.ReceiveFrom(buf, ref servPort);
if (len > 0)
{
data = Encoding.Unicode.GetString(buf, 0, len);
}

return len;
}


}

楼上的代码给我.好像没用.

呵呵，看错问题了，解答如下：

CrossThreadOperationControl sendmsg = delegate()
{
rtLog.Text = "消息……";
rtLog.Select(rtLog.TextLength, 0);
rtLog.ScrollToCaret();
};

rtLog.Invoke(sendmsg);
