怎么样使用 Now 属性返回当前系统日期和时间??????
说明:前台设置一lable,,想这样返回当前系统日期和时间

lable.text=datetime.now.tostring()

问题解决了..

DateTime dt=DateTime.Now ;
            string s;
            s="今天是："+dt.Year.ToString () +"年"+dt.Month.ToString () +"月"+dt.Day.ToString () +"日 ";
            switch(dt.DayOfWeek.ToString ())
            {
                case "Monday":s=s+"星期一";
                    break;
                case "Tuesday":s=s+"星期二";
                    break;
                case "Wednesday":s=s+"星期三";
                    break;
                case "Thursday":s=s+"星期四";
                    break;
                case "Friday":s=s+"星期五";
                    break;
                case "Saturday":s=s+"星期六";
                    break;
                case "Sunday":s=s+"星期天";
                    break;
            }
            lbldate.Text =s;
