Twitterで直接メッセージを送るC＃

Question

次のコードを使用して、他のIDにメッセージを送信しています。誰かが私がここで何が不足しているか説明してください。両方のアカウントはお互いにフォロワーであり、このオプションは全員からの直接メッセージを受信することも可能です。

private static void sendMessage(string message) 
{ 
    //The facebook json url to update the status 
    string facebookURL = "https://api.twitter.com/1.1/direct_messages/new.json?user_id=1699575980&screen_name=MuneebZulfee&text=some message"; 

    //set the access tokens (REQUIRED) 
    string oauth_consumer_key = "**************************"; 
    string oauth_consumer_secret = "***************************"; 
    string oauth_token = "******************************"; 
    string oauth_token_secret = "*****************************"; 

    // set the oauth version and signature method 
    string oauth_version = "1.0"; 
    string oauth_signature_method = "HMAC-SHA1"; 

    // create unique request details 
    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}&screen_name={6}&text={7}&user_id={8}"; 

    string baseString = string.Format(
     baseFormat, 
     oauth_consumer_key, 
     oauth_nonce, 
     oauth_signature_method, 
     oauth_timestamp, oauth_token, 
     oauth_version, 
     Uri.EscapeDataString("MuneebZulfee"), 
     Uri.EscapeDataString("some message"), 
     Uri.EscapeDataString("1699575980") 
    ); 

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

    // create the request header 
    string authorizationFormat = "OAuth 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_consumer_key), 
     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) 
    ); 

    HttpWebRequest objHttpWebRequest = (HttpWebRequest)WebRequest.Create(facebookURL); 
    objHttpWebRequest.Headers.Add("Authorization", authorizationHeader); 
    objHttpWebRequest.Method = "POST"; 
    objHttpWebRequest.ContentType = "application/x-www-form-urlencoded"; 
    using (Stream objStream = objHttpWebRequest.GetRequestStream()) 
    { 
     byte[] content = ASCIIEncoding.ASCII.GetBytes(Uri.EscapeDataString("user_id=1699575980&screen_name=MuneebZulfee&text=some message")); 
     objStream.Write(content, 0, content.Length); 
    } 

    var responseResult = ""; 
    try 
    { 
     //success posting 
     WebResponse objWebResponse = objHttpWebRequest.GetResponse(); 
     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; 
    } 
}
