Need REGEX for the Following

Hi Babu,

You can use the following code - it solves your problem:

        static void Main(string[] args)
        {
            bool result = IsValid("123-456-789");
        }

        private static bool IsValid(string input)
        {
            bool result1 = new Regex("^([0-9]{3}[-][0-9]{3}[-][0-9]{3})$").IsMatch(input);
            bool result2 = new Regex("^([0-9]{9})$").IsMatch(input);

            return result1 || result2;
        }

// Here separate comaprison is done as I am not a regex expert :)
