I am trying to retrieve CodeProject article data for my blog. I have a few questions.

1) Is is legal?
2) Is it safe?
3) I want to get 'Latest Articles' part of the main page. However, I just want the ttile and the link of article. Is it possible?

4) How can i do that if safe and legal?

string url = "http://www.codeproject.com/";
           try
           {
               HttpWebRequest istek = (HttpWebRequest)WebRequest.Create(url);

               istek.AllowAutoRedirect = true;
               istek.Credentials = CredentialCache.DefaultCredentials;
               istek.Proxy = WebRequest.GetSystemWebProxy();
               istek.UseDefaultCredentials = true;
               istek.UserAgent = "CodeProject Bot";
               HttpWebResponse yanit = (HttpWebResponse)istek.GetResponse();
               StreamReader okuyucu = new StreamReader(yanit.GetResponseStream());
               string gelenKaynak = okuyucu.ReadToEnd();
               int IcerikBaslangicIndex = gelenKaynak.IndexOf("<div id=" + '"' + "arttypes" + '"' + ">") + 30;
               int IcerikBitisIndex = gelenKaynak.Substring(IcerikBaslangicIndex).IndexOf("</div>");

               string final = System.Web.HttpUtility.HtmlDecode(gelenKaynak.Substring(IcerikBaslangicIndex, IcerikBitisIndex)).ToString();

               string[] sonuc;
               string[] stringSeparators = new string[] { "<div class=" + '"' + "row" + '"' + ">" };


               sonuc = final.Split(stringSeparators, StringSplitOptions.None);
               return sonuc;
           }
           catch (Exception)
           {

               throw;
           }

I am getting totaly nonsense part of codeproject. What am I missing?
