C sharp 实现银行ATM机程序.doc

用c# 实现银行ATM机项目对于做开发的人来说，没有什么比做出项目、实现功能更开心的事了。以下是使用microsoft visual studio 2008作为开发工具，制作出的银行ATM机的程序程序实现截图程序结构1、新建一个C#项目2、创建如下几个文件1、 Customer.cs文件内容using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace 银行提款机模拟_面向对象_文件访问_ class Customer public Customer(string name,string account, string password,double money) this.Name = name; this.Account = account; this.Password = password; this.money = money; public string Name get;set; public string Accountget;set; public string Password get; set; private double money; public double Money get return money; public bool Save(double money) this.money += money; /this的用法 return true; public bool Draw(double money) if(this.Moneymoney) return false; else this.money -= money; return true; public bool ChangePsw(string newPsw) if(newPsw=this.Password|newPsw=|newPsw=null) return false; else this.Password = newPsw; return true; 2、文件using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace 银行提款机模拟_面向对象_文件访问_ class Machine private List list = new List(); /保存客户的集合 private Customer currentCustomer = null; /表示当前在柜员机上操作的客户 public Machine() /得到所有字符串 string temp = OperFile.ReadFile();/调用之前写好的静态方法 /对字符串按行进行拆分，换行的字符为rn string arr = temp.Split(n, r); /根据每一行的字符串还原出客户对象 foreach (string s in arr) string strs = s.Split(,); if(strs.Length!=4) /采用rn拆分后可能出现无效字符串 continue; Customer c = new Customer(strs0, strs1, strs2, double.Parse(strs3); list.Add(c); /将创建完的客户对象加入到集合中 private void ChangePsw() Console.WriteLine(请输入旧密码); string temp = Console.ReadLine(); Console.WriteLine(请输入新密码); string newPsw = Console.ReadLine(); if (currentCustomer.Password = temp & currentCustomer.Password != newPsw) currentCustomer.Password = newPsw; Console.WriteLine(密码修改成功); else Console.WriteLine(修改不成功); private bool CustomerLogin() Console.WriteLine(请输入卡号); string account = Console.ReadLine(); Console.WriteLine(请输入密码); string psw = Console.ReadLine(); foreach (Customer c in list) if (c.Account = account & c.Password = psw) Console.WriteLine(登录成功); this.currentCustomer = c; return true; else Console.WriteLine(输入有误); return false; return false; private bool Save() Console.WriteLine(请输入要存款的金额); string temp = Console.ReadLine(); double d = double.Parse(temp); currentCustomer.Save(d); Console.WriteLine(存款成功); return true; private bool Draw() Console.WriteLine(请输入要取的金额); string temp = Console.ReadLine(); double d = double.Parse(temp); bool b = currentCustomer.Draw(d); if (b = true) Console.WriteLine(取款成功); return true; else Console.WriteLine(取款不成功); return false; private void QueryMoney() if (currentCustomer != null) /实际上前面几个例子都要写这一句 double d = currentCustomer.Money; Console.WriteLine(您的余额为:0, d); else Console.WriteLine(数据异常); public void MainOperation() /在函数中进行业务流程的定义 bool b = CustomerLogin(); bool isContinue = true; if (b = true) do Console.WriteLine(请选择所需操作:1 取款 ， 2 存款 3 查询余额 ，4 修改密码 ,0 退出); string temp = Console.ReadLine(); switch (temp) case 1: Draw(); break; case 2: Save(); break; case 3: QueryMoney(); break; case 4: ChangePsw(); break; case 5: break; Console.WriteLine(是否继续 Y/N); temp = Console.ReadLine(); if (temp = n) isContinue = false; while (isContinue = true); 3、文件using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.IO;namespace 银行提款机模拟_面向对象_文件访问_ class OperFile / / 将文本写到文件上 / / 要写到文件上的内容 public static void WriteFile(string contents) FileStream fs = new FileStream(Account.txt, FileMode.OpenOrCreate); byte byt = Encoding.Default.GetBytes(contents); fs.Write(byt, 0, byt.Length); fs.Close(); / / 从文件上读取内容 / / 文件上的所有内容 public static string ReadFile() /用于存放最后的结果 string temp = ; FileStream fs = new FileStream(Account.txt, FileMode.Open); /文件不存在，则会出错，出错不管，以后再说 byte byt = new byte1024; int realRead = 0; do realRead=fs.Read(byt,0,byt.Length); temp = temp +Encoding.Default.GetString(byt,0,realRead); /该句性能较差，以后需要优化 while(realRead=byt.Length); fs.Close(); return temp;
