Answer 1

Try using the Html Agility Pack to parse the HTML from your email and extract the href attributes from <a> tags.

HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(emailBody);
foreach (HtmlNode link in doc.DocumentNode.SelectNodes("//a[@href]"))
{
   HtmlAttribute att = link.Attributes["href"];
   string href = att.Value;
}

You could use regular expression even though it is not a perfect solution:

class Program
{
    static void Main(string[] args)
    {
        var text = File.ReadAllText(@"d:\test.htm");

        Regex regex = new Regex("href\\s*=\\s*\"([^\"]*)\"", RegexOptions.IgnoreCase);
        MatchCollection matches = regex.Matches(text);
        foreach(Match match in matches)
        {
            Console.WriteLine(match.Groups[1]);
        }
    }
}
