that regex would look like this:

string pattern = @"\b\d{5}-\d{7}-\d";

Regex.Match(input, @"\b\d{5}-\d{7}-\d$");

This also matches 00000-0000000-0000000000. Shouldn't that be `@"^\d{5}-\d{7}-\d$"`? – Thorsten Dittmar Dec 20 '12 at 09:04

string strRegex = @"[0-9]{5}\-[0-9]{7}\-[0-9]{1}";
RegexOptions myRegexOptions = RegexOptions.None;
Regex myRegex = new Regex(strRegex, myRegexOptions);
string strTargetString = @"12345-1234567-9";

foreach (Match myMatch in myRegex.Matches(strTargetString))
{
  if (myMatch.Success)
  {
    // Add your code here
  }
}
