Answer 1

I think the RegEx you are looking for is this:

(?:^!!PART\|){0,1}(?.*?)(?:,|!!$)

This can then be run like this

        string tag = "!!Part|123456,ABCDEF,ABC132!!";

        string partRegularExpression = @"(?:^!!PART\|){0,1}(?.*?)(?:,|!!$)";
        ArrayList results = new ArrayList();

        Regex extractNumber = new Regex(partRegularExpression, RegexOptions.IgnoreCase);
        MatchCollection matches = extractNumber.Matches(tag);
        foreach (Match match in matches)
        {
            results.Add(match.Groups["value"].Value);
        }            

        foreach (string s in results)
        {
            Console.WriteLine(s);
        }
