❔ Change UDP Port

I've got a question. I'm working on a small GUI where I receive data by UDP. This already works fine. But I want to add the functionality to change the listening port. Here I struggle. Can some one help me?

    public partial class Form1 : Form
    {
        private UdpClient udpClient;
        private List<Measurment> measurments = new List<Measurment>();
        private String serverIdentifier = "-temperature measurement system werner-";
        private IPEndPoint receiveAdr;
        private bool firtTimeReading = true;

        private void btReadData_Click(object sender, EventArgs e)
        {
            if (firtTimeReading)
            {
                receiveAdr = new IPEndPoint(IPAddress.Any, int.Parse(this.nud_port.Value.ToString()));
                udpClient = new UdpClient(receiveAdr);
                this.ReceiveAsync();
                firtTimeReading = false;
            }
            else
            {
                // Do something to change port to another value... here I need help
            }
        }

        private async void ReceiveAsync()   // async bedeutet, dass die Methode im Hintergrund ausgeführt wird
        {
            while (true)
            {
                UdpReceiveResult result = await udpClient.ReceiveAsync();
                string value = Encoding.UTF8.GetString(result.Buffer);
                ...
            }
        }

    public partial class Form1 : Form
    {
        private UdpClient udpClient;
        private List<Measurment> measurments = new List<Measurment>();
        private String serverIdentifier = "-temperature measurement system werner-";
        private IPEndPoint receiveAdr;
        private bool firtTimeReading = true;

        private void btReadData_Click(object sender, EventArgs e)
        {
            if (firtTimeReading)
            {
                receiveAdr = new IPEndPoint(IPAddress.Any, int.Parse(this.nud_port.Value.ToString()));
                udpClient = new UdpClient(receiveAdr);
                this.ReceiveAsync();
                firtTimeReading = false;
            }
            else
            {
                // Do something to change port to another value... here I need help
            }
        }

        private async void ReceiveAsync()   // async bedeutet, dass die Methode im Hintergrund ausgeführt wird
        {
            while (true)
            {
                UdpReceiveResult result = await udpClient.ReceiveAsync();
                string value = Encoding.UTF8.GetString(result.Buffer);
                ...
            }
        }

Looks like nothing has happened here. I will mark this as stale and this post will be archived until there is new activity.
