Title
Body
I tried this code for validating IP address, but it doesn't work... public static bool IP(string ipStr) { string pattern = @"^([1-9]|[1-9][0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])(\.([0-9]|[1-9][0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])){3}$"; Regex check = new Regex (pattern); bool valid = false; if (ipStr == "") { valid = false; } else { valid = check.IsMatch (ipStr, 0); } return valid; } Any idea what's wrong?
