神奇的Bank系统之旅哦

    奋斗不能等待，我们不能等到垂暮之年再去“全力以赴”。让我们从现在开始，为理想而努力，为人生而拼搏。精诚所至，金石为开，相信奋斗会让我们的青春之花绽放得更加绚烂，让我们的人生之路走下来不留遗憾。

一、我带大家看看我的神奇Bank系统思路.

1.我们都知道去银行办理业务都是要有一张属于你自己的卡    所以这里就需要一个卡的类

class Card
      {
          private string cardNo;//卡号
          private string cardOwner;//持卡人
          private string cardPwd;//密码
          private double balance;//余额

          public double Balance
          {
             get { return balance; }
             set { balance = value; }
         }
         public string CardPwd
         {
             get { return cardPwd; }
             set { cardPwd = value; }
         }

         public string CardOwner
         {
             get { return cardOwner; }
             set { cardOwner = value; }
         }

         public string CardNo
         {
             get { return cardNo; }
             set { cardNo = value; }
         }

     }

2.我们去银行就必不可缺少的银行类喽

1.开户  2.存款 3.取款  4.查询余额 5.转账  6.修改密码  7.退出  8.输出所有账户的持卡人以及余额

//开户模块
  Console.WriteLine("欢迎进入开户模块");
              Console.WriteLine("请输入卡号");
              string cardNo = Console.ReadLine();
              Console.WriteLine("请输入密码");
              string cardPwd = Console.ReadLine();
              Console.WriteLine("请输入用户名");
              string cardOwner = Console.ReadLine();
              Console.WriteLine("请输入开户后要存储的金额");
              double balance = double.Parse(Console.ReadLine());
             //将bank里的值重新赋给Card中
             Card card = new Card();
             card.CardNo = cardNo;
             card.CardPwd = cardPwd;
             card.CardOwner = cardOwner;
             card.Balance = balance;

             //将card对象赋值给数组第一个为null的项目
             for (int i = ; i < cards.Length; i++)
             {
                 if (cards[i]==null)
                 {
                     cards[i] = card;
                     Console.WriteLine("开户成功!");
                     break;
                 }
             }

  //存款模块
 Console.WriteLine("请输入您的账号");
             string cardno = Console.ReadLine();
             for (int i = ; i < cards.Length; i++)
            {
                     if (cards[i] != null && cards[i].CardNo == cardno)
                     {
                          flag = true;
                          Console.WriteLine("请输入密码");
                          string pwd = Console.ReadLine();
                         if (cards[i].CardPwd == pwd)
                         {
                             Console.WriteLine("恭喜您登陆成功!请输入您要存款的金额:");
                             double GiveMoney = double.Parse(Console.ReadLine());
                             cards[i].Balance = cards[i].Balance + GiveMoney;
                             Console.WriteLine("恭喜您存款成功,您的当前余额为:{0}", cards[i].Balance);
                             break;
                         }
                         else
                         {
                             Console.WriteLine("您输入的密码有误!");
                             break;
                         }
                     }
             }

 //取款模块

 Console.WriteLine("请输入您的账号");
             string cardno = Console.ReadLine();
             for (int i = ; i < cards.Length; i++)
             {
                 if (cards[i] != null && cards[i].CardNo == cardno)
                 {
                     flag1 = true;
                     Console.WriteLine("请输入密码");
                     string pwd = Console.ReadLine();
                     if (cards[i].CardPwd == pwd)
                     {
                         Console.WriteLine("恭喜您登陆成功!请输入您要取款的金额:");
                         double TakeMoney = double.Parse(Console.ReadLine());
                         cards[i].Balance = cards[i].Balance - TakeMoney;
                         Console.WriteLine("恭喜您存款成功,您的当前余额为:{0}", cards[i].Balance);
                         break;
                     }
                     else
                     {
                         Console.WriteLine("您输入的密码有误!");
                         break;
                     }
                 }
             }

//转账模块

注意!注意!我手写三遍的

 Console.WriteLine("请输入您的账号");
             string cardno = Console.ReadLine();
             for (int i = ; i < cards.Length; i++)
             {
                 if (cards[i] != null && cards[i].CardNo == cardno)
                 {
                     flag2 = true;
                     Console.WriteLine("请输入密码");
                     string pwd = Console.ReadLine();
                     if (cards[i].CardPwd == pwd  && cards[i].Balance!=)
                     {
                         if (cards[i].Balance!=)
                         {
                         Console.WriteLine("恭喜您登陆成功!请输入您要转账的对象账户:");
                         string Target = Console.ReadLine();
                         for (int j = ; j < cards.Length; j++)
                         {
                             if (cards[j].CardNo.Equals( Target) || cards[j].CardNo!=null )
                             {
                                 Console.WriteLine("请输入您的操作金额:");
                                 double Transform = double.Parse(Console.ReadLine());
                                if (Transform < cards[i].Balance && Transform != )
                                 {
                                     cards[i].Balance -= Transform;
                                     cards[j].Balance += Transform;
                                     Console.WriteLine("恭喜您转账成功!您的当前余额为:{0}", cards[i].Balance);
                                  break;
                                 }

                         }
                     }
                     else

//修改密码

复制代码

                 }
             }    

3.退卡相信大家都会啦吧,我就略啦哈......

我的小思路与大家分享如果有错误希望大家可以多多指教

总结:乐学实学，挑战自己；勤勉向上，成就自我。
