Regular expressions C# - is it possible to extract matches while matching?

Question

Say, I have a string that I need to verify the correct format of; e.g. RR1234566-001 (2 letters, 7 digits, dash, 1 or more digits). I use something like:

<

Answer 1

Use grouping and Matches instead.

I.e.:

// NOTE: pseudocode.
Regex re = new Regex("(\\d+)-(\\d+)");
Match m = re.Match(stringToMatch))

if (m.Success) {
  String part1 = m.Groups[1].Value;
  String part2 = m.Groups[2].Value;
  return true;
} 
else {
  return false;
}

You can also name the matches, like this:

Regex re = new Regex("(?\\d+)-(?\\d+)");

and access like this

  String part1 = m.Groups["Part1"].Value;
  String part2 = m.Groups["Part2"].Value;
