MyBank

1.首先分析出顾客类，还有银行类。

2.顾客类具有：用户名，账户，密码，余额，身份证号等属性

3.银行类具有：存钱，取钱，转账，查询，更改密码，注册办理等等功能

4.顾客类：（最好运用属性封装字段）

namespace autoBank
{
    class Person
    {
        public string name;//用户名 public double money;//余额 public string password;//密码 public string idNumber;//身份证号 public string number; //账户 } }

银行类：

Person[] user = new Person[30];//创建顾客类对象数组
        public void CreatAccount()//初始化并添加顾客的方法 { bool result; for(int i=0;i<user.Length;i++) { if(user[i]==null) { user[i]=new Person(); Console.WriteLine("请输入用户名："); user[i].name = Console.ReadLine();
