I wanted to send UdpPacket to a specific remote host (I already know the public IP and Port). I wanted to use C#'s UdpClient class.
static int Main()
{
UdpClient client = new UdpClient();
IPEndPoint remoteEP = new IPEndPoint(IPAddress.Parse("1.2.3.4"), 9999);
byte[] data = GetData();
client.Send(data, data.Length, remoteEP);
}
When sending a packet, the UdpClient choose an available port automatically. I want to manually set the port, from which I send the packets.
Thanks for your help in advance!
Try specifying the endpoint when you create the UdpClient
:
UdpClient client = new UdpClient(localEndpoint);
EDIT: Note that you can also specify just the port number:
UdpClient client = new UdpClient(localPort);
That may be somewhat simpler :)
