RssReader(Linq to xml)

准确地说谈不上是一个阅读器，因为目前只显示rss源的标题

首先用一个xml文档来存储一些rss列表，结构如下：

<?xml version="1.0" encoding="utf-8" ?>
<feeds>
    <feed enable="true">
        <site>幻想曲.Net</site>
        <url>http://www.lemongtree.com</url>
        <rss>http://www.lemongtree.com/rss.axd</rss>
    </feed>
    <feed enable="true">
        <site>大脑门</site>
        <url>http://www.iceapple.net</url>
        <rss>http://www.iceapple.net/syndication.axd</rss>
    </feed>
    <feed enable="true">
        <site>CnBlogs</site>
        <url>http://www.cnblogs.com</url>
        <rss>http://www.cnblogs.com/rss</rss>
    </feed>
    <feed enable="true">
        <site>BlueIdea</site>
        <url></url>
        <rss>http://bbs.blueidea.com/rss.php</rss>
    </feed>
</feeds>

enable属性表示该站点是否有效,false表示无效

展示页面中的dropdownlist数据源就来自于此

选择一个rss源，点击read,显示

[code:c#]

public class RssItem
{

    public RssItem()
    {
        //
        // TODO: Add constructor logic here
        //
    }
    public RssItem(string title, string url, DateTime date)
    {
        Title = title;
        URL = url;
        PubDate = date;
    }
    public string Title { get; set; }
    public string URL { get; set; }
    public DateTime PubDate { get; set; }
    public List<RssItem> GetList(string rssurl)
    {
        List<RssItem> list = new List<RssItem>();
        //try
        //{
            XDocument doc = XDocument.Load(rssurl);
            var feeds = from feed in doc.Descendants("item")
                        select new RssItem
                        {
                            PubDate = Convert.ToDateTime(feed.Element("pubDate").Value),
                            Title = feed.Element("title").Value,
                            URL = feed.Element("link").Value
                        };
            list = feeds.ToList();
        //}
        //catch
        //{

        //}
        return list;
    }
}
