亲们! 首次见面! 带来不适!多多见谅!--------->>Bank系统
讲一下Bank系统的做法:
01.首先创建一个Card类
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace VS1 { //账号类 public class Card { //姓名 public string name; //账号 public string account; //密码 public string password; //身份证号 public string id; //余额 public double balance; } }
02.创建一个Bank类
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace VS1 { //银行类 public class Bank { //定义卡数组 Card[] cards=new Card[100]; #region 01.给原有2卡赋值 public void InitialData() { Console.WriteLine("==========================================="); Console.WriteLine("=================现有卡有==================>>"); //卡1 Card card1 = new Card(); card1.name = "阿乐";//用户名 card1.account = "111111";//卡号 card1.password = "123456";//mima card1.id = "342225199504262055";//身份证号 card1.balance = 1000200;//余额 cards[0] = card1;//把卡值赋值数组 //卡2 Card card2 = new Card(); card2.name = "阿龙"; card2.account = "222222"; card2.password = "654321"; card2.id = "34222519514562115"; card2.balance = 1000200; cards[1] = card2; } #endregion #region 02.欢迎页面 public void Welcome() { Console.WriteLine("欢迎进入天尽头ATM系统，亲");

其中08.转账也可以写为:
//转账 public void TransferMoney() { Console.WriteLine("请输入转出卡卡号"); string outCardNo = Console.ReadLine(); //003 Console.WriteLine("请输入转出卡密码"); string outCardPwd = Console.ReadLine(); //判定用户名和密码是否正确 //循环对比 //定义一个标记，标记指示转出卡号默认是不存在 bool flag = false;//默认转出卡不存在 bool outCardFlag = false;//默认转入卡不存在 int type = 0; foreach (Card card in cards) { if (card!=null) { if (card.CardNo.Equals(outCardNo)) //卡号一致 { flag = true; //判定密码是否一致 if (card.CardPwd.Equals(outCardPwd)) //密码一致 { //用户名 密码均正确，可以执行后续内容 Console.WriteLine("请输入转入卡卡号"); string inCardNo = Console.ReadLine(); #region 内层循环，转入卡 foreach (Card card1 in cards) { if (card1 != null) { if (card1.CardNo.Equals(inCardNo)) //转入卡存在 { type = 1; //存在，可以提示输入转账金额 Console.WriteLine("请输入转账金额"); int money = Convert.ToInt32(Console.ReadLine()); if (money <= card.Balance) //合法 { while (money % 100 != 0) //不是面值100的 { Console.WriteLine("您输入的不合法"); Console.WriteLine("请输入转账金额"); money = Convert.ToInt32(Console.ReadLine()); } //代码执行到这里，证明转账金额合法 //100元 //改变双方的余额 card.Balance -= money; card1.Balance += money; Console.WriteLine("转账成功！"); outCardFlag = true; Console.WriteLine("转出卡余额{0}\t转入卡余额{1}", card.Balance, card1.Balance); } else { Console.WriteLine("余额不足，退出"); } break; } } } #endregion if (outCardFlag == false&&type==0) { Console.WriteLine("转入卡不存在！"); } } else { Console.WriteLine("转出卡密码错误！"); } break; } } } //出了循环，如果flag还是false，就证明没有该卡！ if (flag==false) { Console.WriteLine("没有该卡"); } }
03.最后使用main方法调用输出:
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace Bank { class Program { static void Main(string[] args) { Bank bank=new Bank(); bank.InitialData();//保证数组中前3项有值 bank.PrintCustomerInfo(); bank.Welcome(); Console.ReadKey(); } } }
