问题描述
I want to to do network discovery using UDP Broadcast in C#. I don't know how to do this. Can you give me advice on how to do it?
I want to do like this tutorial.
解决方案
It's very simple to make same thing in C#
Server:
var Server = new UdpClient(8888);
var ResponseData = Encoding.ASCII.GetBytes("SomeResponseData");
while (true)
{
var ClientEp = new IPEndPoint(IPAddress.Any, 0);
var ClientRequestData = Server.Receive(ref ClientEp);
var ClientRequest = Encoding.ASCII.GetString(ClientRequestData);
Console.WriteLine("Recived {0} from {1}, sending response", ClientRequest, ClientEp.Address.ToString());
Server.Send(ResponseData, ResponseData.Length, ClientEp);
}
Client:
var Client = new UdpClient();
var RequestData = Encoding.ASCII.GetBytes("SomeRequestData");
var ServerEp = new IPEndPoint(IPAddress.Any, 0);
Client.EnableBroadcast = true;
Client.Send(RequestData, RequestData.Length, new IPEndPoint(IPAddress.Broadcast, 8888));
var ServerResponseData = Client.Receive(ref ServerEp);
var ServerResponse = Encoding.ASCII.GetString(ServerResponseData);
Console.WriteLine("Recived {0} from {1}", ServerResponse, ServerEp.Address.ToString());
Client.Close();
