Repeater实现超过多少天后不显示New图标

        protected void repNewsList_ItemDataBound(object sender, RepeaterItemEventArgs e)
        {
           if (e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item)
            {
                News attiacl = (News)e.Item.DataItem;
                if (DateTime.Now - attiacl.createddate > new TimeSpan(3, 0, 0, 0))
                {
                    e.Item.Controls[1].Visible = false;
                }
            }
        }
