private static string GetWebText(string url)
    {
        HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url);
        request.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.19 (KHTML, like Gecko) Chrome/18.0.1025.162 Safari/535.19";
        WebResponse response = request.GetResponse();
        Stream stream = response.GetResponseStream();
        StreamReader reader = new StreamReader(stream);
        string htmlText = reader.ReadToEnd();
        return htmlText;
    }

a 2nd example that return a list of lines

private static List<string> GetWebText(string url)
    {
        HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url);
        request.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.19 (KHTML, like Gecko) Chrome/18.0.1025.162 Safari/535.19";
        WebResponse response = request.GetResponse();
        Stream stream = response.GetResponseStream();
        StreamReader reader = new StreamReader(stream);
        List<string> siteLines = new List<string>();
        string line;
        while ((line = reader.ReadLine()) != null)
        {
            siteLines.Add(reader.ReadLine());
        }
        return siteLines;
    }
