这是我通过一个简单的示例所做的工作。

我必须在以下位置从Twitter生成oAuth使用者密钥和机密：

https://dev.twitter.com/apps/new

我首先对身份验证对象进行反序列化以获取令牌，然后再键入以对时间轴调用进行身份验证。

时间轴调用只是读取json，因为这是我需要做的所有事情，您可能想要将其反序列化为一个对象。

我已经在以下位置为此创建了一个项目：https

更新 -我已经更新了github项目，以包括asp .net Web应用程序和mvc应用程序示例演示以及nuget安装。

// You need to set your own keys and screen name
var oAuthConsumerKey = "superSecretKey";
var oAuthConsumerSecret = "superSecretSecret";
var oAuthUrl = "https://api.twitter.com/oauth2/token";
var screenname = "aScreenName";

// Do the Authenticate
var authHeaderFormat = "Basic {0}";

var authHeader = string.Format(authHeaderFormat,
    Convert.ToBase64String(Encoding.UTF8.GetBytes(Uri.EscapeDataString(oAuthConsumerKey) + ":" +
    Uri.EscapeDataString((oAuthConsumerSecret)))
));

var postBody = "grant_type=client_credentials";

HttpWebRequest authRequest = (HttpWebRequest)WebRequest.Create(oAuthUrl);
authRequest.Headers.Add("Authorization", authHeader);
authRequest.Method = "POST";
authRequest.ContentType = "application/x-www-form-urlencoded;charset=UTF-8";
authRequest.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;

using (Stream stream = authRequest.GetRequestStream())
{
    byte[] content = ASCIIEncoding.ASCII.GetBytes(postBody);
    stream.Write(content, 0, content.Length);
}

authRequest.Headers.Add("Accept-Encoding", "gzip");

WebResponse authResponse = authRequest.GetResponse();
// deserialize into an object
TwitAuthenticateResponse twitAuthResponse;
using (authResponse)
{
    using (var reader = new StreamReader(authResponse.GetResponseStream())) {
        JavaScriptSerializer js = new JavaScriptSerializer();
        var objectText = reader.ReadToEnd();
        twitAuthResponse = JsonConvert.DeserializeObject<TwitAuthenticateResponse>(objectText);
    }
}

// Do the timeline
var timelineFormat = "https://api.twitter.com/1.1/statuses/user_timeline.json?screen_name={0}&include_rts=1&exclude_replies=1&count=5";
var timelineUrl = string.Format(timelineFormat, screenname);
HttpWebRequest timeLineRequest = (HttpWebRequest)WebRequest.Create(timelineUrl);
var timelineHeaderFormat = "{0} {1}";
timeLineRequest.Headers.Add("Authorization", string.Format(timelineHeaderFormat, twitAuthResponse.token_type, twitAuthResponse.access_token));
timeLineRequest.Method = "Get";
WebResponse timeLineResponse = timeLineRequest.GetResponse();
var timeLineJson = string.Empty;
using (timeLineResponse)
{
    using (var reader = new StreamReader(timeLineResponse.GetResponseStream()))
    {
         timeLineJson = reader.ReadToEnd();
    }
}


public class TwitAuthenticateResponse {
    public string token_type { get; set; }
    public string access_token { get; set; }
}
