Return Type: Status

Note: The response you receive differs between images and videos. If uploading videos, the code below works well. However, if uploading images, you shouldn’t iterate, waiting for processed status because that happens immediately. See this issue for more info:

• Cannot upload image, Sorry, that page does not exist

v4.x Example:

            string status =
                "Testing video upload tweet #Linq2Twitter £ " +
                DateTime.Now.ToString(CultureInfo.InvariantCulture);

            Media media = await twitterCtx.UploadMediaAsync(File.ReadAllBytes(@"..\..\images\LinqToTwitterMediumTest.mp4"), "video/mp4", "tweet_video");

            Media mediaStatusResponse = null;
            do
            {
                if (mediaStatusResponse != null)
                {
                    int checkAfterSeconds = mediaStatusResponse?.ProcessingInfo?.CheckAfterSeconds ?? 0;
                    Console.WriteLine($"Twitter video testing in progress - waiting {checkAfterSeconds} seconds.");
                    await Task.Delay(checkAfterSeconds * 1000);
                }

                mediaStatusResponse =
                    await
                    (from stat in twitterCtx.Media
                     where stat.Type == MediaType.Status &&
                           stat.MediaID == media.MediaID
                     select stat)
                    .SingleOrDefaultAsync(); 
            } while (mediaStatusResponse?.ProcessingInfo?.State == MediaProcessingInfo.InProgress);

            if (mediaStatusResponse?.ProcessingInfo?.State == MediaProcessingInfo.Succeeded)
            {
                Status tweet = await twitterCtx.TweetAsync(status, new ulong[] { media.MediaID });

                if (tweet != null)
                    Console.WriteLine($"Tweet sent: {tweet.Text}");
            }
            else
            {
                MediaError error = mediaStatusResponse?.ProcessingInfo?.Error;

                if (error != null)
                    Console.WriteLine($"Request failed - Code: {error.Code}, Name: {error.Name}, Message: {error.Message}");
            }
