I need to validate that the user entered text in the format:
####-#####-####-###
Can I do this using Regex.Match?
I would do something like this:
private static readonly Regex _validator =
new Regex(@"^\d{4}-\d{5}-\d{4}-\d{3}$", RegexOptions.Compiled);
private static bool ValidateInput(string input)
{
input = (input ?? string.Empty);
if (input.Length != 19)
{
return false;
}
return _validator.IsMatch(input);
}
