青鸟影院售票系统（一）

        闲话不多说，先抖一张效果图：

     

   好，咱们正式进入主题

           

一、问题分析

1.系统开发步骤

(1)明确需求

(2)设计类

(3)创建项目

(4)确定编码顺序

      1.主窗体

      2.查看新放映列表

      3.查看电影介绍

      4.查看影票票价

     5.查看放映厅座位

     6.购票和打印电影票

     7.继续购票

(5)测试

二、类的设计

 献上这9个类的代码

      （1）Seat 类：保存影院的座位信息

      

public class Seat    {        public Seat(string seatNum, Color color)        {            this.SeatNum = seatNum;            this.Color = color;        }        /// <summary>        /// 座位号        /// </summary>        private string seatNum;        public string SeatNum        {            get { return seatNum; }            set { seatNum = value; }        }        /// <summary>        /// 显示售出与否的颜色属性        /// </summary>        private Color color;        public Color Color        {            get { return color; }            set { color = value; }        }    }

      （2）Movie：电影类
