[C#].NET 4.5 New Feature - Regex match with timeout

        AppDomain.CurrentDomain.SetData("REGEX_DEFAULT_MATCH_TIMEOUT", TimeSpan.FromSeconds(2));
        isMatch = IsMatch(input, pattern);

        Console.WriteLine();
        isMatch = IsMatch(input, pattern, TimeSpan.FromSeconds(4));
    }

    static Boolean IsMatch(string input, string pattern)
    {
        try
        {
            return Regex.IsMatch(input, pattern, RegexOptions.None);
        }
        catch (RegexMatchTimeoutException ex)
        {
            // handle exception
            Console.WriteLine("Match timed out!");
            Console.WriteLine("- Timeout interval specified: " + ex.MatchTimeout);
            Console.WriteLine("- Pattern: " + ex.Pattern);
            Console.WriteLine("- Input: " + ex.Input);
        }

        return false;
