------解决方案--------------------
Linq的XDocument的LastNode ，看帮助
或者用XmlDocument的SelectNodes 找到一组，然后访问最后有一个索引的Node
------解决方案--------------------
看看xpath
XmlDocument x = new XmlDocument();
x.Load(@"c:\test.xml");
XmlNodeList xnl = x.SelectNodes("//data/info[last()]/timestamp");
foreach (XmlNode xn in xnl)
{
Console.WriteLine(xn.InnerText);
