ListTweetOnUserTimeline returns null

Question

I'm using TweetSharp for C#, and I'm successfully able to publish tweets to twitter via this.

However, I'm trying to read the most recent tweets from the account's timeline, but I keep getting null back every time I try to get the data. The following code returns null

  string consumerKey = <consumerKey>;
  string consumerSecret = <consumerSecret>;

  TwitterService service = new TwitterService(consumerKey, consumerSecret);
        service.AuthenticateWith(consumerKey, consumerSecret);
        var options = new ListTweetsOnUserTimelineOptions()
        {
            ScreenName = screenName,
            SinceId = 0,
            Count = 5
        };
       var currentTweets = service.ListTweetsOnUserTimeline(options);

I've tried using UserId instead of ScreenName, but I still get null as a result fir currentTweets. All the examples I can find are pointing to this method, but it doesn't work.

Any Ideas?

Answer 1

I think your problem is the AuthenticateWith call. You appear to be passing the consumer token and secret again, but the AuthenticateWith overload that takes only two arguments expects a user token and secret. I suspect you are therefore getting an unauthorised response (not sure why you don't get an error).

I would suggest either removing the AuthenticateWith call (you've already provided the consumer token in the constructor), or changing it so you pass details for a valid user token instead of the consumer one.

You could also check the Response property on the twitter service after your call completes, and inspect the http status code/reason phrase/content etc. to see if that gives you more detail about what is going wrong.
