udp服务器

问题描述

大家好，
伙计们，我刚刚构建了一个简单的udp服务器，那就是代码:

Hello every one ,
Guys I just built a simple udp server and that''s the code :

private void Form1_Load(object sender, EventArgs e)
        {
            Thread thdUDPServer = new Thread(new
ThreadStart(serverThread));
            thdUDPServer.Start();
        }

        public void serverThread()
{
UdpClient udpClient = new UdpClient(8080);
while(true)
{
    IPEndPoint RemoteIpEndPoint = new IPEndPoint(IPAddress.Any, 0);
    Byte[] receiveBytes = udpClient.Receive(ref
RemoteIpEndPoint);
    string returnData = Encoding.ASCII.GetString(receiveBytes);
    lbConnections.Items.Add(
    RemoteIpEndPoint.Address.ToString() + ":" +
    returnData.ToString()
    );
}
}
    }
}

但是每次我运行程序时，都会出现以下错误:

跨线程操作无效:从创建该线程的线程之外的线程访问控件"lbConnections".

所以请帮助我

But every time when i run the program the following error appears:

Cross-thread operation not valid: Control ''lbConnections'' accessed from a thread other than the thread it was created on.

so please help me
