如何在Windows Media Player中播放YouTube视频?

我已经在form1设计了一个windows media player控件。 这就是我获取视频列表并将其添加到listBox的方式:

static List<string> videosList = new List<string>();
        public async void RetrieveUploadsList()
        {
            UserCredentials();
            var youtubeService = new YouTubeService(new BaseClientService.Initializer()
            {
                HttpClientInitializer = credential,
                ApplicationName = Assembly.GetExecutingAssembly().GetName().Name
            });

            var channelsListRequest = youtubeService.Channels.List("contentDetails");
            channelsListRequest.Mine = true;
            var channelsListResponse = await channelsListRequest.ExecuteAsync();
            foreach (var channel in channelsListResponse.Items)
            {
                var uploadsListId = channel.ContentDetails.RelatedPlaylists.Uploads;

                Console.WriteLine("Videos in list {0}", uploadsListId);

                var nextPageToken = "";
                while (nextPageToken != null)
                {
                    var playlistItemsListRequest = youtubeService.PlaylistItems.List("snippet");
                    playlistItemsListRequest.PlaylistId = uploadsListId;
                    playlistItemsListRequest.MaxResults = 50;
                    playlistItemsListRequest.PageToken = nextPageToken;
                    var playlistItemsListResponse = await playlistItemsListRequest.ExecuteAsync();

                    foreach (var playlistItem in playlistItemsListResponse.Items)
                    {
                            videosList.Add(playlistItem.Snippet.Title + "  " + playlistItem.Snippet.ResourceId.VideoId);
                            listBox1.Items.Add(playlistItem.Snippet.Title + "  " + playlistItem.Snippet.PublishedAt);
                    }
                    nextPageToken = playlistItemsListResponse.NextPageToken;
                }
            }
            if (this.listBox1.Items.Count > 0)
                this.listBox1.SelectedIndex = 0;
        }

没有我在listBox中的所有视频列表和已经选择的第一个项目。选择第一个项目后,我想在Windows媒体播放器中显示所选项目视频第一个图像(帧),就像在youtube中看到第一个图像(帧),然后它们开始播放。

而且,当我点击Windows媒体播放器播放按钮时,它将播放视频。 (我是否需要先下载视频?或者它将从youtube上网播放?)

Windows Media Player变量是:

axWindowsMediaPlayer1

我怎样才能做出这两件事?
