    How about this:

    string[] domains = text.Replace(" ",",").Replace("http://", "").Replace("www.", "").Replace("ftp://", "").Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries);

    Then you can check each string for a valid url

    public static bool isValidUrl(string url)
{
    string pattern = @"^[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(:[a-zA-Z0-9]*)?/?([a-zA-Z0-9\-\._\?\,\'/\\\+&%\$#\=~])*[^\.\,\)\(\s]$";
    Regex reg = new Regex(pattern, RegexOptions.Compiled | RegexOptions.IgnoreCase);
    return reg.IsMatch(url);
}

    Hope it helps…

    EDIT: Sorry, the validation failed..Fixed it now…
