在youtube api .net中通过ID获取youtube播放列表

我正在尝试用c# . net程序从YouTube播放列表中下载最新的项目。现在，我有一个程序，它使用"channel. contentdetails . relatedplaylists .Uploads"从我的频道的Uploads播放列表中成功获取必要的数据，这是我从API页面上的示例程序中获得的。但我在api文档中找不到任何信息，关于如何切换这一行或周围的行，以获得播放列表的ID，而不是我自己的上传。

这不是重复的，因为本页上的其他示例解释了如何通过http链接找到它，如"http://gdata.youtube.com/feeds/api/playlists/…"等。我想直接通过API的方法来实现。下载数据的代码部分如下所示。

private async Task Run()
{
    var youtubeService = new YouTubeService(new BaseClientService.Initializer()
    {
        ApiKey = "API KEY HERE",
        ApplicationName = this.GetType().ToString()
    });
    //MAYBE I NEED TO CHANGE THIS? SOMETHING LIKE
    //'youtubeservice.Playlists.IDUNNOWHAT'
    var channelsListRequest = youtubeService.Channels.List("contentDetails");
    channelsListRequest.Id = "CHANNEL ID HERE";
    // Retrieve the contentDetails part of the channel resource for the authenticated user's channel.
    var channelsListResponse = await channelsListRequest.ExecuteAsync();
    foreach (var channel in channelsListResponse.Items)
    {

        //OR MAYBE I NEED TO CHANGE THIS PART? 
        //LIKE 'channel.ContentDetails.SOMETHING
        var uploadsListId = channel.ContentDetails.RelatedPlaylists.Uploads;

        var nextPageToken = "";
        while (nextPageToken != null)
        {
            var playlistItemsListRequest = youtubeService.PlaylistItems.List("snippet");
            playlistItemsListRequest.PlaylistId = uploadsListId;
            playlistItemsListRequest.MaxResults = 50;
            playlistItemsListRequest.PageToken = nextPageToken;
            // Retrieve the list of videos uploaded to the authenticated user's channel.
            var playlistItemsListResponse = await playlistItemsListRequest.ExecuteAsync();
            /*
            * DO A BUNCH OF STUFF WITH THE YOUTUBE DATA
            */
            nextPageToken = playlistItemsListResponse.NextPageToken;
        }
    }
}
