为了熟悉C#的委托与事件，用委托与事件实现简单的银行卡与储蓄卡的还款功能

前言

信用卡还款是银行系统的重要业务，业务流程说明如下：

用户有信用卡和储蓄卡，储蓄卡有查询余额和取款功能，信用卡能够查看账单金额、查看还款日和查看余额三个功能；
请使用委托与事件实现下列功能：用户可自由设置信用卡还款关联的储蓄卡，当还款日到期时进行账单金额的自动划扣；
请注意事件主要是设计什么时候启动委托，委托的主要目的是设置还款的储蓄卡
为避免设计出现偏差，给出了部分功能代码，请在此基础上进行开发。

一、基本框架

namespace ConsoleApplication3delegate

{

    class DepositCard

    {

        public int amount;



        public void Display()

        {

            Console.WriteLine("储蓄卡余额为：{0}", amount);

        }

        public void Account(int balance,int payday)

        {

            amount += balance;

            Console.WriteLine("今天是本月的｛0｝，取款｛1｝，储蓄卡余额为：{2}。", 
            DateTime.Today.Day,balance,amount);

        }

    }



    class CreditCard

    {

        private int billamount;

        private int repaymentday;



        public CreditCard(int billamount, int repaymentday)

        {

            this.billamount = billamount;

            this.repaymentday = repaymentday;

        }



        public int getbillamount() {return billamount;}



        public int getrepaymentday() { return repaymentday;}



        public void Display(){Console.WriteLine("信用卡余额为：{0}", billamount);}



       

    }



    class CreditCardDelegate

    {

        public int billamount;

        public int repaymentday;

       //请在此处添加自己的代码



    }

    class Program

    {

        static void Main(string[] args)

        {

            DepositCard depositCard = new DepositCard();

            depositCard.amount = 10000;

            CreditCard creditCard1 = new CreditCard(-2000,9);

            CreditCard creditCard2 = new CreditCard(-3000, 13);

            CreditCard creditCard3 = new CreditCard(-5000, 29);

            depositCard.Display(); Console.WriteLine("");

            List<CreditCard> Cards = new List<CreditCard>();

            Cards.Add(creditCard1); Cards.Add(creditCard2); Cards.Add(creditCard3);



            foreach (CreditCard card in Cards)

            {

                Console.WriteLine("信用卡开始执行委托还款。。。。。。");

              //请在此处添加自己的代码

                Console.WriteLine("");

            }

            

           Console.ReadLine();

        }

    }

}

二、具体部分实现

1.实现委托与事件

由于题目要求，可知这个委托主要应该是对储蓄卡的操作，获取储蓄卡相关信息的方法为account它的形参为（int，int）所以将委托也设置为（int，int）便于添加。

代码如下：

public delegate void Carddelegate(int c, int d1);

public class CreditCardDelegate
    {
        public int billamount;
        public int repaymentday;
        
       
        public event Carddelegate Orderhandle;

        public void action(int balance,int payday)
        {
            if (Orderhandle != null)
            {
                Orderhandle(balance,payday);
            }
        }
        //请在此处添加自己的代码
    }

2.功能实现

代码如下：

Timer t = new Timer();
int date = DateTime.Today.Day;
int date1 = DateTime.Today.Month;
int[] monthday = { 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31 };//设置时间
//其实感觉有点多余对于这个例子，可以只取这个月

CreditCardDelegate Corder = new CreditCardDelegate();//创建委托
    Corder.Orderhandle += depositCard.Account;//将储蓄卡的方法添加进去   
    foreach (CreditCard card in Cards)//遍历每一张卡
           
    {
                
         for (int i = 1; i <= monthday[date1]; i++)
         {//循环是遍历每个月的最大天数到期还款
                    
            if (date==card.getrepaymentday() )
            {//当满足需要还款的时间时执行还款
                 Console.WriteLine("信用卡开始执行委托还款。。。。。。");
                 Corder.action(card.getbillamount(), date);
                 date++;//执行完过一天
                 break;
             }
             else
             {
                 t.Interval = 1000;
                 date++;//不到还款日
              }//请在此处添加自己的代码
              }
                Console.WriteLine("");
       }
       Console.ReadLine();
