菜鸟级:动态绑定时间

//后台

DateTime tnow = DateTime.Now;//现在时间
        int yeartimes=int.Parse(tnow.Year.ToString());//当前时间年
        int monthtimes = int.Parse(tnow.Month.ToString());//当前时间月
        ArrayList AlYear = new ArrayList();
        int i;
        for (i = yeartimes; i>= 1950; i--)
            AlYear.Add(i);
        ArrayList AlMonth = new ArrayList();
        for (i = 1; i <= monthtimes; i++)
            AlMonth.Add(i);

        DDl_SYear.DataSource = AlYear;
        DDl_SYear.DataBind();//绑定年

        DDl_EYear.DataSource = AlYear;
        DDl_EYear.DataBind();//绑定年

        DDl_SMonth.DataSource = AlMonth;
        DDl_SMonth.DataBind();//绑定月

        DDl_EMonth.DataSource = AlMonth;
        DDl_EMonth.DataBind();//绑定月

//前台
