C# Oauth不是'；t授权读取请求

好的，这是代码

 class Program
 {
    static void Main(string[] args)
    {
        var oauth_token = "somekey";
        var oauth_token_secret = "somekey";
        var oauth_consumer_key = "somekey";
        var oauth_consumer_secret = "somekey";

        var oauth_version = "1.0";
        var oauth_signature_method = "HMAC-SHA1";
        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();
        var resource_url = "http://api.twitter.com/1/statuses/update.xml";
        //var resource_url = "http://api.twitter.com/1/statuses/home_timeline.xml";
        var status = "Another Status Update 3";

        var baseFormat = "oauth_consumer_key={0}&oauth_nonce={1}&oauth_signature_method={2}" +
            "&oauth_timestamp={3}&oauth_token={4}&oauth_version={5}&status={6}";

        var baseString = string.Format(baseFormat,
                                    oauth_consumer_key,
                                    oauth_nonce,
                                    oauth_signature_method,
                                    oauth_timestamp,
                                    oauth_token,
                                    oauth_version,
                                    Uri.EscapeDataString(status)
                                    );

        baseString = string.Concat("POST&", Uri.EscapeDataString(resource_url),
                     "&", Uri.EscapeDataString(baseString));

        var compositeKey = string.Concat(Uri.EscapeDataString(oauth_consumer_secret),
                    "&", Uri.EscapeDataString(oauth_token_secret));

        string oauth_signature;
        using (HMACSHA1 hasher = new HMACSHA1(ASCIIEncoding.ASCII.GetBytes(compositeKey)))
        {
            oauth_signature = Convert.ToBase64String(
                hasher.ComputeHash(ASCIIEncoding.ASCII.GetBytes(baseString)));
        }

        var headerFormat = "OAuth oauth_nonce=\"{0}\", oauth_signature_method=\"{1}\", " +
               "oauth_timestamp=\"{2}\", oauth_consumer_key=\"{3}\", " +
               "oauth_token=\"{4}\", oauth_signature=\"{5}\", " +
               "oauth_version=\"{6}\"";

        var authHeader = string.Format(headerFormat,
                                Uri.EscapeDataString(oauth_nonce),
                                Uri.EscapeDataString(oauth_signature_method),
                                Uri.EscapeDataString(oauth_timestamp),
                                Uri.EscapeDataString(oauth_consumer_key),
                                Uri.EscapeDataString(oauth_token),
                                Uri.EscapeDataString(oauth_signature),
                                Uri.EscapeDataString(oauth_version)
                        );

        // Requesting now

        var postBody = "status=" + Uri.EscapeDataString(status);

        ServicePointManager.Expect100Continue = false;

        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(resource_url);
        request.Headers.Add("Authorization", authHeader);
        request.Method = "POST";
        request.ContentType = "application/x-www-form-urlencoded";
        using (Stream stream = request.GetRequestStream())
        {
            byte[] content = ASCIIEncoding.ASCII.GetBytes(postBody);
            stream.Write(content, 0, content.Length);
        }
        WebResponse response = request.GetResponse();

        Console.WriteLine("Now attempting to display homepage");

    }
 }
}

好的，现在的问题是，上面的代码可以很好地通过POST编写状态更新。然而，每当我尝试使用它的变体时

Console.WriteLine("Attempting to read");

        //var postBody = "status=" + Uri.EscapeDataString(status);

        ServicePointManager.Expect100Continue = false;

        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(resource_url);
        request.Headers.Add("Authorization", authHeader);
        request.Method = "POST";
        request.ContentType = "application/x-www-form-urlencoded";
        /*using (Stream stream = request.GetRequestStream())
        {
            byte[] content = ASCIIEncoding.ASCII.GetBytes(postBody);
            stream.Write(content, 0, content.Length);
        }*/

        WebResponse response = request.GetResponse();

要接收状态更新，代码只是在

WebResponse=request.GetResponse（）处崩溃并发送未经授权的消息。为什么它被授权写作而不是阅读。任何关于从哪里开始的帮助，我们都将不胜感激。
如果您有机会，您需要这样做

WebResponse response = request.GetResponse();

做这样的事

var response = (HttpWebResponse)page.GetResponse();

我已经解决了阅读问题，似乎我忘了在request.method属性中将“POST”替换为“GET”。无论如何，非常感谢您阅读了这么长的代码。
