Question

我只想在这里解析一个RSS提要，我可以用XmlReader来做这个

String blogrss = @"http://belvederecollegeac.wordpress.com/feed/";

             using (System.Xml.XmlReader reader = System.Xml.XmlReader.Create(blogrss))
    {
        System.ServiceModel.Syndication.SyndicationFeed feed = System.ServiceModel.Syndication.SyndicationFeed.Load(reader);

        foreach (var v in feed.Items)
        {
            string title = v.Title.Text.Replace("•", "  ---  ");
            string url = v.Id; 

            string link = "<a href=" + url + ">" + title + "</a>"; 

            Response.Write(link + "<br><br>");

        }

但我找不到xml阅读器如何给我描述节点？

我可以获得v.Tite和v.Id（用于链接），但RSS包含一个描述节点，例如

<description>

我的feed.Items集合似乎没有附加到它的对象称为描述？

Answer 1

没有Description属性。使用Summary属性。它在以下文档中描述

http://msdn.microsoft.com/en-us/library/system.servicemodel.syndication.syndicationitem.summary.aspx

“当序列化为Atom 1.0时，此属性将写入摘要元素。当序列化为RSS 2.0时，此属性将写入描述元素。”

如何在RSS源中获取非标准项？
