i have this code, and i want to upload image to twitter,

how can i do it ?

string twitterURL = "https://api.twitter.com/1.1/statuses/update_with_media.json";


       BLEnumHelper m_BLEnumHelper = new BLEnumHelper();
       BLGodsProfile userprofile = new BLGodsProfile();
       tbmgodsprofile godsAccessToken = userprofile.GetGodsByIdGods(m_strIdGods);

       string oauth_token = godsAccessToken.twittertoken;
       string oauth_token_secret = godsAccessToken.twitterpin;
       string oauth_consumerKey = System.Configuration.ConfigurationManager.AppSettings["TwitterConsumerKey"];
       string oauth_consumerSecret = System.Configuration.ConfigurationManager.AppSettings["TwitterConsumerSecret"];

       string oauth_version = "1.0";
       string oauth_signature_method = "HMAC-SHA1";

       string oauth_nonce = Convert.ToBase64String(new ASCIIEncoding().GetBytes(DateTime.Now.Ticks.ToString()));
       System.TimeSpan timeSpan = (DateTime.UtcNow - new DateTime(1970, 1, 1, 0, 0, 0, 0, DateTimeKind.Utc));
       string oauth_timestamp = Convert.ToInt64(timeSpan.TotalSeconds).ToString();

       // create oauth signature
       string baseFormat = "oauth_consumer_key={0}&oauth_nonce={1}&oauth_signature_method={2}" + "&oauth_timestamp={3}&oauth_token={4}&oauth_version={5}&status={6}";

       string baseString = string.Format(
           baseFormat,
           oauth_consumerKey,
           oauth_nonce,
           oauth_signature_method,
           oauth_timestamp, oauth_token,
           oauth_version,
           Uri.EscapeDataString(message)
       );

       string oauth_signature = null;
       using (HMACSHA1 hasher = new HMACSHA1(ASCIIEncoding.ASCII.GetBytes(Uri.EscapeDataString(oauth_consumerSecret) + "&" + Uri.EscapeDataString(oauth_token_secret))))
       {
           oauth_signature = Convert.ToBase64String(hasher.ComputeHash(ASCIIEncoding.ASCII.GetBytes("POST&" + Uri.EscapeDataString(twitterURL) + "&" + Uri.EscapeDataString(baseString))));
       }

       // create the request header
       string authorizationFormat = "OAuth realm=\"{7}\", oauth_consumer_key=\"{0}\", oauth_nonce=\"{1}\", " + "oauth_signature=\"{2}\", oauth_signature_method=\"{3}\", " + "oauth_timestamp=\"{4}\", oauth_token=\"{5}\", " + "oauth_version=\"{6}\"";

       string authorizationHeader = string.Format(
           authorizationFormat,
           Uri.EscapeDataString(oauth_consumerKey),
           Uri.EscapeDataString(oauth_nonce),
           Uri.EscapeDataString(oauth_signature),
           Uri.EscapeDataString(oauth_signature_method),
           Uri.EscapeDataString(oauth_timestamp),
           Uri.EscapeDataString(oauth_token),
           Uri.EscapeDataString(oauth_version),
           Uri.EscapeDataString(twitterURL)
       );

       HttpWebRequest objHttpWebRequest = (HttpWebRequest)WebRequest.Create(twitterURL);
       objHttpWebRequest.ContentType = "application/x-www-form-urlencoded";
       objHttpWebRequest.Headers.Add("Authorization", authorizationHeader);
       objHttpWebRequest.Method = "POST";
       using (Stream objStream = objHttpWebRequest.GetRequestStream())
       {
           byte[] content = ASCIIEncoding.ASCII.GetBytes("status=" + Uri.EscapeDataString(message));
           content = ASCIIEncoding.ASCII.GetBytes("media[]=" + @"D:\TgByPiwi\TG\TgUi\images\chartshare\24jpeg");
           objStream.Write(content, 0, content.Length);
       }

       var responseResult = "";
       try
       {
           //success posting
           WebResponse objWebResponse = objHttpWebRequest.GetResponse() as HttpWebResponse;
           StreamReader objStreamReader = new StreamReader(objWebResponse.GetResponseStream());
           responseResult = objStreamReader.ReadToEnd().ToString();
       }
       catch (Exception ex)
       {
           //throw exception error
           responseResult = "Twitter Post Error: " + ex.Message.ToString() + ", authHeader: " + authorizationHeader;
       }

it's seem like i lost something in this code, cause, i can't upload it, and also not getting some error code.
