[C#] Collecting part of output stream and putting it into a list

Does this work? I wrote the code directly into this post, so I may have made errors

Code:

string pattern = @"(?<Number>\d+?)\.\s+?(?<License>(?:\d|\w){8}-(?:(?:\d|\w){4}-){3}(?:\d|\w){12})";

Regex regex = new Regex(pattern);

MatchCollection matches = regex.Matches(yourStringWithData);

// This can be changed to <int, string> if you want to convert the number into an integer type with int.Parse() or int.TryParse().
Dictionary<string, string> licenses = new Dictionary<string, string>();

foreach (Match match in matches)
{
    string number = match.Groups["Number"].Value;
    string license = match.Groups["License"].Value;

    // Use the matched strings
    licenses.Add(number, license);
}

// All licenses can now be accessed from the dictionary

 

Glad you got it working This is a revised version that disregards the 0.'s - just posting it for future reference

Code:

using System.Collections.Generic;
using System.Text.RegularExpressions;

string pattern = @"(?:\d|\w){8}-(?:(?:\d|\w){4}-){3}(?:\d|\w){12}";

Regex regex = new Regex(pattern);

MatchCollection matches = regex.Matches(yourStringWithData);

List<string> licenses = new List<string>();

foreach (Match match in matches)
{
    string license = match.Value.ToLowerInvariant().Trim(); // For casing consistency, and removes eventual spaces

    licenses.Add(license);
}
