C#影院售票系统毕业设计(1)

时间:2020-10-16 12:40:18 | 栏目:.NET代码 | 点击:

 C#学习经历从基本语法结构到窗体再到面向对象终于走完了.NET初级程序员的道路,用了大概一天半的时间做完这个练手项目《影院售票系统》,先上效果截图一张

抽出时间做些这个对目前的我来说算不小的项目。

用到的知识点有:面向对象思想、TreeView、XML读取、File文件流、泛型集合,这里面对我来说难度最大的是面向对象与泛型集合的结合,看来学习一门编程语言的难点还是在设计思想上。

再来介绍一下项目需求:在影片列表中选择某个时段的一场电影,单击座位选择一个种类的电影票,并创建电影,计算价格并打印影票信息,然后该座位被置为红色表示已经售出。

影院每天更新放映列表,系统支持实时查看,包括电影放映场次时间、电影概况。

影院提供三类影票:普通票、赠票和学生票(赠票免费;学生票有折扣)

允许用户查看某场次座位的售出情况

支持购票,并允许用户选座

用户可以选择场次、影票类型及空闲座位进行购票,并打印电影票

系统可以保存销售情况,并允许对其进行恢复

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,根据依赖编写类的顺序,不能完全按照上面顺序
