In C# you can use capturing groups

    private void RegexTest()
    {
        String input = "foo[]=1&foo[]=5&foo[]=2";
        String pattern = @"foo\[\]=(\d+)";

        Regex regex = new Regex(pattern);

        foreach (Match match in regex.Matches(input))
        {
            Console.Out.WriteLine(match.Groups[1]);
        }
    }
