请使用委托实现信用卡用户定时还款功能。

using System.Text;
using System.Threading.Tasks;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            credituser c = new credituser(1000, 10000,9,10);
            System.Timers.Timer atimer = new System.Timers.Timer();
            atimer.Elapsed += new ElapsedEventHandler(c.dealdebt);
            atimer.Interval = 10000;
            atimer.Enabled = true;
            Console.ReadKey();
        }
    }
    class credituser
    {
        private double indebt;
        private double save;
        private int hour;
        private int minute;
        public credituser(double indebt,double save,int hour,int minute) {
            this.indebt = indebt; this.save = save;
            this.hour = hour; this.minute = minute;
        }

        public void debtandsave()
        {
            Console.WriteLine("debt:{0},save:{1}",this.indebt,this.save);
        }
        public void dealdebt(object source, ElapsedEventArgs e)
        {
            Console.WriteLine("进入定时监控程序......");
            int intHour = e.SignalTime.Hour;
            int intMinute = e.SignalTime.Minute;
            if (this.hour==intHour && this.minute==intMinute)
            {
                this.indebt=this.indebt - 100<0?0:this.indebt-100;
                save -= 100;
                this.hour += 1;
                Console.WriteLine("开始执行！");
                debtandsave();

            }

        }
    }
}
