xmlRss.WriteElementString（「image」，「imagedata」）;

編輯：好的使用內置的整合支持。

  var feed = new SyndicationFeed(); 

     var items = new List<SyndicationItem>(); 

     foreach (var item in rssItems) 
     { 
      var syndicationItem = new SyndicationItem 
      { 
       Title = item.Title, 
       Content = item.Description, 
       PublishDate = item.PublishDate, 

      }; 

      syndicationItem.ElementExtensions.Add(new XElement("image", item.Image)); 
      syndicationItem.AddPermalink(new Uri(item.Link)); 

      items.Add(syndicationItem); 
     } 

     feed.Items = items; 

     using (var xml = new XmlTextWriter(Response.OutputStream, Encoding.UTF8)) 
     { 
      feed.SaveAsRss20(xml); 
     }
