用Repeater绑定数据时，如何在时间字段那加个判断，如果时间小于当前系统时间3天，则日期用红色字表示。 ...

#region// 自定义判断时间和头像
    protected void rpComment_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        if (e.Item.ItemType != ListItemType.Header && e.Item.ItemType != ListItemType.Footer)
        { 
       //判断时间间隔
            Literal ltTime = e.Item.FindControl("lteTime") as Literal;
            HiddenField HFtime = e.Item.FindControl("HFTime") as HiddenField;
            string datetime = System.DateTime.Now.ToString();
            System.DateTime addTime = DateTime.Parse(HFtime.Value);
            System.DateTime nowTime = DateTime.Parse(datetime);
            System.TimeSpan timeSpan = nowTime - addTime;
            ConvertNum cn = new ConvertNum();//定义转换阿拉伯数字转换为中文大写
            if (timeSpan.TotalDays > 3)//判断天
            {
ltTime.Text = "于 " +cn.NumToChn(timeSpan.TotalDays.ToString("00")) + " 天之前说：";
           }              
        }
}

 

<asp:HiddenField  ID="HFTime" Value='<%#Eval("postdatetime") %>' runat="server"/>
                        <asp:Literal ID="lteTime" runat="server"></asp:Literal>
