Question

I’m trying to ping a server based on an IP Address and a port, using the Ping class,
I have to convert the IP Address to an array of bytes, how am I doing it?
I took this method from somewhere

 bool IsConnectedToInternet
    {
        get
        {
            Uri url = new Uri("www.abhisheksur.com");
            string pingurl = string.Format("{0}", url.Host);
            string host = pingurl;
            bool result = false;
            Ping p = new Ping();
            try
            {

                PingReply reply = p.Send(host, 3000);
                if (reply.Status == IPStatus.Success)
                    return true;
            }
            catch { }
            return result;
        }
    }

I just have to ping the server based on an IP, not a URL.
Thank you.

Use the IPAddress class and Ping.Send(IPAddress address) method. If you’re trying to convert from IPAddress to bytes, it offers handy hosttonetwork and networktohost methods.
