401尝试调用Twitter流API时出错

我已经无计可施了，我已经看遍了这里，虽然有人问过类似的问题，但我还找不到确切的答案。

我一直在试着打电话https://stream.twitter.com/1.1/statuses/filter.json在C#控制台应用程序中运行了几天，并不断出现401未经授权的错误，无论我做什么都不会消失。适用于任何不流式传输的内容。

const string streamUrl = "https://stream.twitter.com/1.1/statuses/filter.json";
const string oauth_token = "XXX-XXXXX";
const string oauth_token_secret = "XXXXXXXXXXXX";
const string oauth_consumer_key = "XXXXXXXXXXXXX";
const string oauth_consumer_secret = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX";
// oauth implementation details
const string oauth_version = "1.0a";
const string oauth_signature_method = "HMAC-SHA1";
// unique request details
var oauth_nonce = Convert.ToBase64String(
    new ASCIIEncoding().GetBytes(DateTime.Now.Ticks.ToString()));
var timeSpan = DateTime.UtcNow
    - new DateTime(1970, 1, 1, 0, 0, 0, 0, DateTimeKind.Utc);
var oauth_timestamp = Convert.ToInt64(timeSpan.TotalSeconds).ToString();
// create oauth signature
const string baseFormat = "oauth_consumer_key={0}&oauth_nonce={1}&oauth_signature_method={2}" +
    "&oauth_timestamp={3}&oauth_token={4}&oauth_version={5}&track=twitter";
var baseString = string.Format(baseFormat,
    oauth_consumer_key,
    oauth_nonce,
    oauth_signature_method,
    oauth_timestamp,
    oauth_token,
    oauth_version);
string oauth_signature;
var compositeKey = string.Concat(Uri.EscapeDataString(oauth_consumer_secret),
    "&", Uri.EscapeDataString(oauth_token_secret));
using (var hasher = new HMACSHA1(Encoding.ASCII.GetBytes(compositeKey)))
{
    oauth_signature = Convert.ToBase64String(hasher.ComputeHash(Encoding.ASCII.GetBytes(baseString)));
}
// create the request header
const string headerFormat = "OAuth oauth_consumer_key='"{0}'", oauth_nonce='"{1}'", " +
    "oauth_signature='"{2}'", oauth_signature_method='"{3}'", " +
    "oauth_timestamp='"{4}'", oauth_token='"{5}'", " +
    "oauth_version='"{6}'"";
var authHeader = string.Format(headerFormat,
    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));
const string postparameters = "track=twitter";
streamUrl = string.Format("{0}?{1}", streamUrl, postparameters);
while (true)
{
    var timeLineRequest = (HttpWebRequest)WebRequest.Create(streamUrl);
    timeLineRequest.Headers.Add("Authorization", authHeader);
    var encode = System.Text.Encoding.GetEncoding("utf-8");
    ServicePointManager.Expect100Continue = false;
    if (postparameters.Length > 0)
    {
        timeLineRequest.Method = "POST";
        timeLineRequest.ContentType = "application/x-www-form-urlencoded;charset=UTF-8";
        byte[] _twitterTrack = encode.GetBytes(postparameters);
        timeLineRequest.ContentLength = _twitterTrack.Length;
        Stream _twitterPost = timeLineRequest.GetRequestStream();
        _twitterPost.Write(_twitterTrack, 0, _twitterTrack.Length);
        _twitterPost.Close();
    }
    var webResponse = (HttpWebResponse)timeLineRequest.GetResponse();
    var responseStream = new StreamReader(webResponse.GetResponseStream(), encode);
    while (true)
    {
        var jsonText = responseStream.ReadLine();
        //Success
        int wait = 250;
        //Write Status
        var status = string.Empty;
        var json = new DataContractJsonSerializer(status.GetType());
        byte[] byteArray = Encoding.UTF8.GetBytes(jsonText);
        var stream = new MemoryStream(byteArray);
        status = json.ReadObject(stream) as string;
        Console.Beep();
        Console.WriteLine(status);
    }               
}

如果有其他人通过了这一关，我将不胜感激。我受够了诅咒。
