Asp.net mvc 4 在Asp.net MVC4中按频道名称检索youtube视频时出错

我正在尝试通过Asp.net mvc4 web应用程序中的频道名称检索youtube视频。我尝试用找到的所有代码进行谷歌搜索和测试，但结果是“请求执行失败：” 。任何帮助都将不胜感激，我仍在尝试用谷歌搜索解决方案。 谢谢

型号

public class Youtube
    {
        public string YouTubeMovieID { get; set; }
        public string YouTubeMovieTitle { get; set; }
    }

    public class YouTubeHelper
    {
        const string YT_CHANNEL_NAME = "Heaven Luk";
        const string YT_DEVELOPER_ID = "Devloper ID here";

        public static List<Youtube> GetVideos()
        {
            YouTubeRequestSettings ytSettings = new YouTubeRequestSettings("MyTestingWebsite", YT_DEVELOPER_ID);
            YouTubeRequest ytRequest = new YouTubeRequest(ytSettings);
            string feedURL = String.Format("http://gdata.youtube.com/feeds/api/users/{0}/uploads?orderby=published", YT_CHANNEL_NAME);
            Feed<Video> videoFeed = ytRequest.Get<Video>(new Uri(feedURL));

            return (from video in videoFeed.Entries
                    select new Youtube() { YouTubeMovieID = video.VideoId, YouTubeMovieTitle = video.Title }).ToList();
        }

V2 YouTube API已被弃用。您应该改用V3。如果你想获得频道上传的视频，你必须提供频道名称或ID，获取上传播放列表，然后从该播放列表中获取视频。请参阅代码示例。或者，您也可以通过指定频道ID并设置

type=video

来为给定频道的视频设置

@model IEnumerable<MyTestingProject.Models.YouTubeHelper>
@{

    Layout = "~/Views/Shared/_Foundation.cshtml";
}

@foreach (var v in Model)
{
<object width="427" height="258">
           <param name="movie" value="http://www.youtube.com/v/@v.YouTubeMovieID" />
           <param name="allowFullScreen" value="true" />
           <param name="allowscriptaccess" value="always"/>
           <param name="wmode" value="opaque" />
           <embed src="http://www.youtube.com/v/@v.YouTubeMovieID"
              type="application/x-shockwave-flash" width="427"
              height="258" allowscriptaccess="always" allowfullscreen="true"
              wmode="opaque"></embed>  </object>

}

 public ActionResult Videos()
        {
            var videos = YouTubeHelper.GetVideos();
            return View(videos);
        }
