An item with the same key has already been added in LinqToTwitter search

Question

I made a method to return a list of tweets given their IDs using LinqToTwitter but I get this error message when query is performed:

"An item with the same key has already been added."

StackTrace:

at System.Threading.Tasks.Task.ThrowIfExceptional(Boolean includeTaskCanceledExceptions) at System.Threading.Tasks.Task1.GetResultCore(Boolean waitCompletionNotification) at System.Threading.Tasks.Task1.get_Result() at LinqToTwitter.TwitterQueryable1.GetEnumerator() at System.Collections.Generic.List1..ctor(IEnumerable1 collection) at System.Linq.Enumerable.ToList[TSource](IEnumerable1 source)

Here is my code:

private IList<Tweet> GetTweets()
{
   TwitterContext ctx = new TwitterContext(this.CrateAuth());
   IList<Tweet> tweets = new List<Tweet>();

   var foundTweets =
   (from tweet in ctx.Status
    where tweet.Type == StatusType.Show &&
    (tweet.ID == 522564774706831362 || tweet.ID == 522922846293884929)
         select tweet).ToList();

    foreach (var tweet in foundTweets)
    {
        tweets.Add(
            new Tweet
            {
                ImageUrl = tweet.User.ProfileImageUrl,
                ScreenName = tweet.User.ScreenNameResponse,
                Text = tweet.Text,
                Date = tweet.CreatedAt
            });
    }

    return tweets;
}

Answer 1

I realized that I need StatusType.Lookup instead of StatusType.Show. My query should be:

var foundTweets =
(from tweet in ctx.Status
 where tweet.Type == StatusType.Lookup &&
       tweet.TweetIDs == "522564774706831362,522922846293884929"
 select tweet).ToList();
