I have 2 datagridview(same). I want to transform 2.datagridview to ipnumber from ipadress with this code piece;
long result = 0;
            if (!string.IsNullOrWhiteSpace(ip))
            {
                string[] temp = ip.Trim().Split('.');
                if (temp != null && temp.Count() > 3)
                {
                    string[] lastPart = temp[3].Split(':', ',', ' ');//Port verisinin gelmesi durumunda portu ayirmak için kullaniyoruz
                    result = long.Parse(temp[0]) * 256 * 256 * 256 +
                               long.Parse(temp[1]) * 256 * 256 +
                               long.Parse(temp[2]) * 256 +
                               //long.Parse(temp[3]);
                               long.Parse(lastPart[0]);
                }
            }
