Html Agility Pack help

this is how i achieved. Note that there is a code error given in main Html Agility Pack Example in foreach line doc.DocumentElement.SelectNodes("//a[@href"]). The correct and tested one is given below.

 HtmlWeb hw = new HtmlWeb();

    HtmlDocument doc = hw.Load(@"http://adityabajaj.com");
    StringBuilder sb = new StringBuilder();

    List<string> lstHref = new List<string>();

    foreach (HtmlNode link in doc.DocumentNode.SelectNodes("//a[@href]").Distinct())
    {
        string curHref = link.Attributes["href"].Value;

        if(!lstHref.Contains(curHref))
        lstHref.Add(curHref);

    }
    foreach (string str in lstHref)
    {
        sb.Append(str +"<br />");
    }

    Response.Write (sb.ToString());

Since it got working for me, I thought I should share.

Use HtmlAgilityPack.HtmlDocument:

HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();

The compiler is getting confused because two of the namespaces you have imported with using contain classes called HtmlDocument - the HTML Agility Pack namespace, and the Windows Forms namespace. You can get around this by specifying which class you want to use explicitly.
