<?xml version="1.0" encoding="utf-8" ?>
<backup>
  <item num="1" time ="2009-02-24 0:00:00"></item>
  <item num="2" time="2009-02-25 12:00:00"></item>
</backup>

protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            DataTable dt = new DataTable();
            DataColumn dc = new DataColumn("num");
            dt.Columns.Add(dc);
            dc = new DataColumn("time");
            dt.Columns.Add(dc);

            XmlDocument xmlDoc = new XmlDocument();
            xmlDoc.Load(Server.MapPath("~/XMLFile.xml"));  //xml文件的路径
            XmlNodeList xnl = xmlDoc.SelectSingleNode("backup").ChildNodes;

            for (int i = 0; i < xnl.Count; i++)
            {             
                string num = xnl.Item(i).Attributes["num"].Value;
                string time = xnl.Item(i).Attributes["time"].Value;

                DataRow dr = dt.NewRow();
                dr[0] = num;
                dr[1] = time;
                dt.Rows.Add(dr);
            }
         
            for (int i = 0; i < dt.Rows.Count; i++)
            {
                DataRow dr = dt.Rows[i];
                ListBox1.Items.Add(new ListItem(dr["time"].ToString(), dr["num"].ToString()));
            }
        }
    }

如果用Linq更简单：

//引用using System.Xml.Linq;
XDocument doc = XDocument.Load(Server.MapPath("~/XMLFile.xml"));
var list = from p in doc.Descendants("item")
            select new
            {
                num = (int)p.Attribute("num"),
                time = (DateTime)p.Attribute("time")
            };
foreach (var v in list)
{
    ListBox1.Items.Add(new ListItem(v.time.ToString(), v.num.ToString()));
}
