PerformRedirect = authUrl => Response.Redirect(authUrl) };
if(!Page.IsPostBack){
wbAuthorizer.CompleteAuthorization(Request.Url);
}
if(string.IsNullOrEmpty(objCredenciales.ConsumerKey) || string.IsNullOrEmpty(objCredenciales.ConsumerSecret)){
lblRegistrado.Text = "No estas autorizado aun";
btnAutorizar.Visible = true;
btnTweets.Visible = false;

var UltimosTweets = objTwitter.getHomeTimeLine(wbAuthorizer, intCantidadTweets);
foreach (var Tweet in UltimosTweets) {
this.spnTweets.InnerHtml = "<div class='twitterTweet'>" +

"</div>";
}

}catch(Exception ex){ }
}
}
}
********** And I have another class
Class ConfiguracionTwitter{
public ConfiguracionTwitter(){}
public IEnumerable<Status> getHomeTimeLine(WebAuthorizer auth,int intCantidadTweets) {
twitterContexto= new TwitterContext(auth);
var tweets =
(from tweet in twitterContexto.Status
where tweet.Type == StatusType.Home
select tweet).Take(intCantidadTweets).ToList();
return tweets;
}
}

Answer 1

A "401 Unauthorized" means that your application is unable to authenticate with Twitter. There are many things that can cause a 401. I've compiled a FAQ that will give you a list of things to check:

BTW, posting your OAuth keys makes your application insecure. You should visit your app on the Twitter page as soon as possible and generate a new set of keys.
