Youtube .NET Data API: Retrieve only videoID?

问题

I am using youtube's .NET API to retrieve video feeds, here is the code:

        String[] ids;
        YouTubeRequestSettings settings = new YouTubeRequestSettings("My App Name", "My App Key");
        YouTubeRequest request = new YouTubeRequest(settings);
        Uri uri =
        new Uri("http://gdata.youtube.com/feeds/api/users/nptelhrd/uploads?max-results=50");//Change "GoogleDevelopers" to "default"
        Google.GData.Client.Feed<Video> videoFeed = request.Get<Video>(uri);
        ids = new String[videoFeed.TotalResults];

        int count = 0;
        for (int i = 0; i < 50; i++)
            ids[i] = videoFeed.Entries.ElementAt(i).VideoId;
        for (int i = 50; i < ids.Length-50; i+=50)
        {

            Uri uri2 =
   new Uri("http://gdata.youtube.com/feeds/api/users/nptelhrd/uploads?max-results=50&start-index=" + i.ToString());//Change "GoogleDevelopers" to "default"
            Google.GData.Client.Feed<Video> videoFeed2 = request.Get<Video>(uri);
            for (int j = 0; j < 50; j++)
            {
                ids[i+j] = videoFeed2.Entries.ElementAt(j).VideoId;
                count++;
            }
        }

The above code returns every information(Title, Description, ViewCount, Rating....etc.) for each video uploaded by the user "nptelhrd". There are 6950 videos uploaded by this particular user.

THE ABOVE CODE TAKES 15 MINUTES TO EXECUTE on a 512Kbps connection, because it retrieves all information of each and every video, its painfully slow, wastes a lot of server resources. Can't the above code be modified so that it only retrieve videoId's? How can I only retrieve videoId's of all videos?

With the present limitations of .NET YOUTUBE API, its not possible to retrieve only VIDEOID.
