Post a status update to twitter using c#

Question

Every Example I can find is either very outdated or always comes back 401. Can anyone at all provide a working example of posting a status update to twitter?

Even the below always fails. I get redirected to twitter - great. I can confrim the access codes are correct and match my application, but on acutally posting the update - error is unknown...

What on earth is wrong here? Does matter what app I use or which twitter account.

Using Twitteriser2.dll

if (Request["oauth_token"] == null)
        {
            OAuthTokenResponse reqToken = OAuthUtility.GetRequestToken(
                oauth_consumer_key,
                oauth_consumer_secret,
                Request.Url.AbsoluteUri);

            Response.Redirect(string.Format("http://twitter.com/oauth/authorize?oauth_token={0}",
                reqToken.Token));
        }
        else
        {
            string requestToken = Request["oauth_token"].ToString();
            string pin = Request["oauth_verifier"].ToString();

            var tokens = OAuthUtility.GetAccessToken(
                oauth_consumer_key,
                oauth_consumer_secret,
                requestToken,
                pin);

            OAuthTokens accesstoken = new OAuthTokens()
            {
                AccessToken = tokens.Token,
                AccessTokenSecret = tokens.TokenSecret,
                ConsumerKey = oauth_consumer_key,
                ConsumerSecret = oauth_consumer_secret
            };

            TwitterResponse<TwitterStatus> response = TwitterStatus.Update(
                accesstoken,
                "Testing!! It works (hopefully).");

            if (response.Result == RequestResult.Success)
            {
                Response.Write("we did it!");
            }
            else
            {
                Response.Write("it's all bad.");
            }
        }

Answer 1

The TwitterRepsonse object has an "ErrorMessage" property. You should probably start by looking at the information in there to give you some guidance.

Answer 2

Why don't you use Tweetinvi. Tweetinvi will allow you to post in 1 line and get error messages in line too. Here is an example.

TwitterCredentials.SetCredentials("Access_Token", "Access_Token_Secret", "Consumer_Key", "Consumer_Secret");
var tweet = Tweet.PublishTweet("Hello!");

if (tweet == null)
{
    var exceptionDetails = ExceptionHandler.GetLastException().TwitterExceptionInfos.First().Message;
}

You can find the documentation here : https://tweetinvi.codeplex.com/documentation

Also have a look at https://tweetinvi.codeplex.com/discussions/536895 if you are using it with ASP.NET.

Answer 3

Got it working eventually. The fault isn't exactly known as I didn't have to change the code but what I did was re-download Twitterizwer and Built it (Required adding a ref to C++ components for what ever reason) and it then worked so I can only see that it was somehow faulty the first time round.
