我正在尝试获取media：content的url值，当我循环遍历联合项目时：

            foreach (SyndicationItem item in feed.Items)
            {

                foreach (SyndicationElementExtension extension in item.ElementExtensions)
                {
                    XElement ele = extension.GetObject<XElement>();
                    MessageBox.Show(ele.Value);
                }


            }

我得到空白数据，如何获取媒体内容的网址？

Answer 1

你试过了吗？

XElement ele = extension.GetObject<XElement>();
if (ele.Name.LocalName == "content")
{
   MessageBox.Show(ele.Attribute("url").Value);
}

Answer 2

foreach (var item in feed.Items)
{
    var content = item.ElementExtensions
                      .FirstOrDefault(ext => ext.OuterName == "content")
                      .GetObject<XmlElement>().InnerText    
}

使用syndicationitem获取自定义rss feed item元素？
