Answer 2

You might want to try actually parsing the page and transversing the DOM.

Answer 3

HTML Agility Pack is ideal for this; this is almost the same as the example on the home page:

foreach(HtmlNode link in doc.DocumentElement.SelectNodes("//a[@href]")
{
    string href = link["href"].Value;
}

Now just parse "href"; perhaps something like:

Match match = Regex.Match(href, @"[&?]\w+=(\d+)");
int i;
if (match.Success && int.TryParse(match.Groups[1].Value, out i))
{
    Console.WriteLine(i);
}
