在syndicationFeed中使用syndicationItem？

using syndicationItem in syndicationFeed?

我有类似的东西

 Stream stream = e.Result;
                    XmlReader response = XmlReader.Create(stream);
                    SyndicationFeed feeds = SyndicationFeed.Load(response);
                    foreach (SyndicationItem ff in feeds.Items)
                    {

                        RssItem rssItem = new RssItem(ff.Title.Text, ff.Summary.Text, ff.PublishDate.ToString(), ff.Links[0].Uri.AbsoluteUri, **ff.image?????** );
                        rssItems.Add(rssItem);
                    }

任何帮助??

推荐答案

流stream = e.Result;

Stream stream = e.Result;

        XmlReader response = XmlReader.Create(stream);

        SyndicationFeed feeds = SyndicationFeed.Load(response);

        foreach (SyndicationItem item in feeds.Items)
        {
            if (item.ElementExtensions.Where(p => p.OuterName == "thumbnail").Count() != 0)
            {
                string imgPath = item.ElementExtensions.Where(p => p.OuterName == "thumbnail").First().GetObject<XElement>().Attribute("url").Value;
                MessageBox.Show(imgPath); //use it to show the img in DIV or whereever you wish.
            }

        }
