使用C#生成XML(RSS)的两种方式

代码片段：

foreach (var article in Articles.GetArticles())
{
    XElement item = new XElement("item");
    XElement title = new XElement("title", article.Title);
    wholeUrl = string.Format("{0}?id={1}&catelog={2}", fixedUrl, article.ID, article.Catelog);
    XElement link = new XElement("link", wholeUrl);
    XElement description = new XElement("description", article.Description);
    XElement pubDate = new XElement("pubDate", article.LastMod.ToString());
    item.Add(title, link, description, pubDate);
    channel.Add(item);
}
