how can I get list of active LAN user using ARP

Question

in command prompt we can get list of ACTIVE user's IP [on LAN] using command like

arp - g

How can I get similar list using C#

Why don't you run that command as you normally would, and look at the result from your program? — Joe, Dec 20 '13 at 16:21

You can use Process to execute commands from c# program

Try This:

        Process process = new Process();
        ProcessStartInfo startInfo = new ProcessStartInfo();
        startInfo.FileName = "arp";
        startInfo.Arguments = "-g";
        startInfo.RedirectStandardOutput = true;
        startInfo.UseShellExecute = false;
        process.StartInfo = startInfo;

        process.Start();
        String strData = process.StandardOutput.ReadToEnd();
