关于给DataList中的Label赋值的问题？

protected void DataList4_ItemDataBound(object sender, DataListItemEventArgs e)
    {
        string sql4 = "select  top 8 * from job order by id desc";
        OleDbDataReader dr = helper.reader(sql4);
        dr.Read();

            string oldtime = dr["EndTime"].ToString();
            string newtime = DateTime.Now.ToString("yyyy-MM-dd");
            DateTime t1 = DateTime.Parse(oldtime);
            DateTime t2 = DateTime.Parse(newtime);
            TimeSpan ts = t1 - t2;
            int dats = ts.Days;
            if (dats <= 0)
            {
                Label lb = (Label)e.Item.FindControl("label2");
                lb.Text = "已过期";
            }
            else
            {
                Label lb = (Label)e.Item.FindControl("label2");
                lb.Text = "未过期";
            }
    }

这是我的代码，可是每条记录的 label 显示的都是一样的，不是已过期就是未过期，这个错在哪里啊，拜托大家了 --------------------编程问答-------------------- if (dats <= 0)
            {
                Label lb = (Label)e.Item.FindControl("label2");
                lb.Text = "已过期";
            }
            else
            {
                Label lb = (Label)e.Item.FindControl("label2");
                lb.Text = "未过期";
            }
你这样写肯定不是已过期就是未过期啊 --------------------编程问答-------------------- Label lb = (Label)e.Item.FindControl("label2");
lb.Text = "未过期";
if (dats <= 0)
{
     lb.Text = "已过期";
}

      string oldtime = dr["EndTime"].ToString();

            string newtime = DateTime.Now.ToString("yyyy-MM-dd");

            DateTime t1 = DateTime.Parse(oldtime);

            DateTime t2 = DateTime.Parse(newtime);

            TimeSpan ts = t1 - t2;

            int dats = ts.Days;

Label lb = (Label)e.Item.FindControl("label2");

            if (dats <= 0)

            {

               // Label lb = (Label)e.Item.FindControl("label2");

                lb.Text = "已过期";

            }

            else

--------------------编程问答-------------------- 哈哈  顶
string oldtime = dr["EndTime"].ToString();
            string newtime = DateTime.Now.ToString("yyyy-MM-dd");
            DateTime t1 = DateTime.Parse(oldtime);
            DateTime t2 = DateTime.Parse(newtime);
            TimeSpan ts = t1 - t2;
            int dats = ts.Days;
Label lb = (Label)e.Item.FindControl("label2");
            if (dats <= 0)
            {
               // Label lb = (Label)e.Item.FindControl("label2");
                lb.Text = "已过期";
            }
            else
            {
                //Label lb = (Label)e.Item.FindControl("label2");
