I'm a newbie in C# and asp.net.
I'm trying to create a simple web(run on localhost) which use streaming and search API of Twitter.
I've tried some query like: "https://api.twitter.com/1.1/statuses/mentions_timeline.json?count=2&since_id=14927799" but it got some error about "Bad Authentication data".
May be I don't know how to get Authentication. So could anyone help me? THanks a lots.
What you have shown is not the search functionality, rather is the stream functionality.
Here is a complete example of working twitter stream search

var oauth_token = System.Configuration.ConfigurationManager.AppSettings["accessToken"];

var timeSpan = DateTime.UtcNow - new DateTime(1970, 1, 1, 0, 0, 0, 0, DateTimeKind.Utc);
var oauth_timestamp = Convert.ToInt64(timeSpan.TotalSeconds).ToString();
// message api details
var status = "Updating status via REST API if this works";
var resource_url = "https://api.twitter.com/1.1/search/tweets.json";
var screen_name = "TODO : UPDATE THIS OR LEAVE BLANK";

First you should create an application. https://dev.twitter.com/apps .
Then you can use Twitterizer's WebRequestBuilder class to form your request. ( http://svn.twitterizer.net/twitterizer/trunk/Twitterizer2/OAuth/ )
var tokens = new Twitterizer.OAuthTokens
{
ConsumerKey = "....",
ConsumerSecret = "....",
AccessToken = "....",
AccessTokenSecret = "......"
};
string url = "https://api.twitter.com/1.1/statuses/mentions_timeline.json?count=2&since_id=14927799";
var builder = new Twitterizer.WebRequestBuilder(new Uri(url), Twitterizer.HTTPVerb.GET, tokens);
var req = builder.PrepareRequest();
var resp = req.GetResponse();
var json = new StreamReader(resp.GetResponseStream()).ReadToEnd();
resp.Close();

I'm trying to connect to twitter api from my c# application using the "GET" requests. I read the following article:
