Hi Linvi,

I've created application with your great library. I follow your instruction in other thread to get tweet from timeline with specific hashtag but this error always comes up.

I have no idea to solve this. i've try to save key in configuration file, i've try to change my timezone, dan try to change access level on dev.twitter.com but doesn't work.

Here my app: LoadHashtag
can you give the clue to solve this?

A 401 Exception is usually related with credentials being incorrect.
I will have a look when I have some time available tonight.

In the meantime please do not put your project as public with your credentials information :)

Hi there,

I have read your code and you are currently trying to parse the result on your own because Search of tweet is not provided in 0.8.3.x.
Hopefully the 0.9 (development version) has such a feature and as the release draw nearer I would advise you to use it.

You can only download it from the Source Code download and find examples in Examplinvi as always.

Simple Example using 0.9:
var tweets = Search.SearchTweets("#tweetinvi");

foreach (var tweet in tweets)
       Console.WriteLine("{0}", tweet.Text);
Complex search example using 0.9:
TwitterCredentials.TokenCredentials = new TokenCredentials(

var searchParameter = Search.GenerateSearchTweetParameter("tweetinvi");

searchParameter.SetGeoCode(Geo.GenerateCoordinates(-122.398720, 37.781157), 1, DistanceMeasure.Miles);
searchParameter.Lang = Language.English;
searchParameter.SearchType = SearchResultType.Popular;
searchParameter.MaximumNumberOfResults = 100;
searchParameter.Until = new DateTime(2013, 12, 1);
searchParameter.SinceId = 399616835892781056;
searchParameter.MaxId = 405001488843284480;

var tweets = Search.SearchTweets(searchParameter);

foreach (var tweet in tweets)
    Console.WriteLine("{0}", tweet.Text);
Please let me know if this helps you.

Sorry for the delay,

You helped me identify a bug. I will update the code tonight. In the meantime you can solve your problem this way:
var tweets = Search.SearchTweets("#tweetinvi".TwitterEncode());
You will need to add this namespace:
using TweetinCore.Extensions;
Thank you for the feedback :D

Happy this work for you.

How to get searchresult without Retweet??

If I understand correctly you want to be able to search Twitter but not select any retweet, only original tweet.
I will have a look tonight in the Twitter API Resources to see if there is such a feature but I am not sure.
I will report to you and if there is will implement this tonight or during the weekend.

If you have some time before me please have a look and let me know.

Twitter does not provide such a feature (using twitter search) consequently instead of having a query sent to twitter that performs this action I will need to filter the results. It means that the number of tweets returned by the query will be less than the maximum number of tweets expected if a filter is applied.

I will post the code when I implemented it tonight but the filtering code should look like this :
var searchParameter = Search.GenerateSearchTweetParameter("#tweetinvi");
searchParameter.TweetSearchFilter = TweetSearchFilter.OriginalTweetsOnly;
var tweets = Search.SearchTweets(searchParameter);
This Feature has been added to the list of taks here, you can subscribe to it to receive an email when this is done (tonight ;).

If you download the latest version of tweetinvi from the Source Code you will be able to use the code provided above.
This has not yet been tested so the ticket is not closed yet but you should be able to use it properly :)
