C# udp 问题？我要实现一直发送，我现在发送一次就结束了？

Question

                                       

     private void udp()
        {


                textBox4.Text = string.Empty;
                UdpClient udpclient = new UdpClient(Convert.ToInt32(textBox9.Text));
                udpclient.Connect(textBox8.Text, Convert.ToInt32(textBox9.Text));
                byte[] sendBytes = Encoding.Default.GetBytes(textBox5.Text);
                udpclient.Send(sendBytes, sendBytes.Length);
                IPEndPoint ipendpoint = new IPEndPoint(IPAddress.Any, 0);
                Byte[] receiveBytes = udpclient.Receive(ref ipendpoint);
                string returnData = Encoding.Default.GetString(receiveBytes);
                textBox4.Text += "【这条信息来自主机" + ipendpoint.Address.ToString() + ":" + ipendpoint.Port.ToString() + "】:" + returnData.ToString();
                udpclient.Close();


        }

我要实现一直发送，我现在发送一次就结束了。

Answer 1

你只调用一次Send方法当然就发送一次了，一直发送的话把发送的代码放到一个循环里面。

类似如下：

while(true)

{

udp();

Thread.Sleep(1000);//1秒发送一次

}

补充：用线程或者同步的Dictionary控制，每次需要时候发起一个线程，在线程里边做发送，防止界面假死。
