使用SyndicationItem類在rss feed中顯示圖像

Question

我使用System.ServiceModel.Syndication創建rss feed

public ActionResult RSS()
        {
            List<C_Node> rssNodes = GetNodeList(takeNum: 20).ToList();
            var syndItems = new List<SyndicationItem>();
            foreach (var item in rssNodes)
            {
                var syndItem = new SyndicationItem()
                {
                    Id = item.NodeId.ToString(),
                    Title = SyndicationContent.CreatePlaintextContent(String.Format("{0}", item.Title)),
                    Summary = SyndicationContent.CreateHtmlContent(HelperMethods.Truncate(item.Details,400)),
                    Content = SyndicationContent.CreateHtmlContent(item.Details),
                    PublishDate = item.PostDate
                };
                //syndItem.ElementExtensions.Add("content:encoded", "", SyndicationContent.CreateHtmlContent(item.Details));
                syndItem.Links.Add(SyndicationLink.CreateAlternateLink(new Uri(ConfigurationManager.AppSettings["SiteUrl"] + Url.Action("Details", "Node", new { id = item.NodeId }))));//Nothing alternate about it. It is the MAIN link for the item.
                syndItems.Add(syndItem);
            }

            return new RssFeed(title: Resources.Site.Title,
                               items: syndItems,
                               contentType: "application/rss+xml",
                               description: Resources.Site.Slogan);
        }

我的問題是如何在每個聯合項目中顯示圖像？

Answer 1

添加此代碼完成：

syndItem.ElementExtensions.Add(new XElement("image", item.ImageUrl));

Answer 2

此代碼也有效

syndItem.ElementExtensions.Add(new XElement("enclosure", new XAttribute("type", "image/jpeg"), new XAttribute("url", item.ImageUrl).CreateReader());
