Retrieve your url web page through this method:

private static string retrieveData(string url)
    {
        // used to build entire input
        StringBuilder sb = new StringBuilder();

        // used on each read operation
        byte[] buf = new byte[8192];

        // prepare the web page we will be asking for
        HttpWebRequest request = (HttpWebRequest)
        WebRequest.Create(url);
        request.Timeout = 10; //10 millisecond
        // execute the request

        HttpWebResponse response = (HttpWebResponse)
        request.GetResponse();

        // we will read data via the response stream
        Stream resStream = response.GetResponseStream();

        string tempString = null;
        int count = 0;

        do
        {
            // fill the buffer with data
            count = resStream.Read(buf, 0, buf.Length);

            // make sure we read some data
            if (count != 0)
            {
                // translate from bytes to ASCII text
                tempString = Encoding.ASCII.GetString(buf, 0, count);

                // continue building the string
                sb.Append(tempString);
            }
        }
        while (count > 0); // any more data to read?

        return sb.ToString();
    }

And to use the HTML Agility pack and retrive the html tag like this:

public static string htmlRetrieveInfo()
    {
        string htmlSource = retrieveData("http://example.com/test.html");
        HtmlDocument doc = new HtmlDocument();
        doc.LoadHtml(htmlSource);
        if (doc.DocumentNode.SelectSingleNode("//body") != null)
        {
          HtmlNode node = doc.DocumentNode.SelectSingleNode("//body");
        }
        return node.InnerHtml;
    }
