如何在C＃中将视频上传到youtube特定的channelID

Question

我可以使用以下代码将视频成功上传到C＃中的我的YouTube帐户：

        private async Task Run(string videoFile, string dateStamp)
    {
        UserCredential credential;
        using (var stream = new FileStream("client_secrets.json", FileMode.Open, FileAccess.Read))
        {
            credential = await GoogleWebAuthorizationBroker.AuthorizeAsync(
                GoogleClientSecrets.Load(stream).Secrets,
                // This OAuth 2.0 access scope allows an application to upload files to the
                // authenticated user's YouTube channel, but doesn't allow other types of access.
                new[] { YouTubeService.Scope.Youtubepartner},
                "user",
                CancellationToken.None
            );
        }

        var youtubeService = new YouTubeService(new BaseClientService.Initializer()
        {
            HttpClientInitializer = credential,
            ApplicationName = Assembly.GetExecutingAssembly().GetName().Name
        });

        var video = new Video();
        video.Snippet = new VideoSnippet();
        video.Snippet.Title = string.Format("{0} - La Jolla boat launch timelapse", dateStamp);
        video.Snippet.Description = "Daily TimeLapse of the boat launch area.";
        video.Snippet.Tags = new string[] { "LaJolla", "timelapse" };
        video.Snippet.CategoryId = "22"; // See https://developers.google.com/youtube/v3/docs/videoCategories/list
        video.Snippet.ChannelId = "UC8LB7gACPEoNxdAK6LM-L6A";
        video.Snippet.ChannelTitle = "TimeLapse La Jolla";
        video.Status = new VideoStatus();
        video.Status.PrivacyStatus = "public"; // or "private" or "public"
        var filePath = videoFile; // Replace with path to actual movie file.


        using (var fileStream = new FileStream(filePath, FileMode.Open))
        {
            var videosInsertRequest = youtubeService.Videos.Insert(video, "snippet,status", fileStream, "video/*");
            videosInsertRequest.ProgressChanged += videosInsertRequest_ProgressChanged;
            videosInsertRequest.ResponseReceived += videosInsertRequest_ResponseReceived;

            await videosInsertRequest.UploadAsync();
        }
    }

但是，我的YouTube帐户中有3个频道，并希望上传到特定频道。上面的代码将上传到我的主帐户而不会出现问题，但不会上传到提供的渠道ID。频道名称和ID是正确的 - 但这不起作用，因为我希望视频在频道中显示为新上传。我无法找到此功能的其他信息。有什么建议吗？
