C#总结项目《影院售票系统》编写总结一

来源:互联网 时间:1970-01-01

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,做为品德优良好学生更不能落下课程的总结项目-某某鸟《影院售票系统》。用了大概一天半的时间做完这个练手项目,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

二.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

三、类的设计

1.Seat:保存影院的座位信息,主要属性如下

座位号(SeatNum):string类型

座位卖出状态颜色(Color):System.Drawing.Color类型

         2.Movie:电影类

           电影名(MovieName):string类型

           海报图片路径(Poster):string类型

           导演名(Director):string类型

           主演(Actor):string类型

           电影类型(MovieType):MovieType自定义枚举类型

           定价(Price):int类型

         3.Ticket:电影票父类,保存电影票信息

           放映场次(ScheduleItem):ScheduleItem自定义类

           所属座位对象(Seat):Seat自定义类型

           票价(Price):int类型

           计算票价的虚方法CalcPrice()

           打印售票信息的虚方法Print()

           显示当前售出票信息的虚方法Show()

         4.StudentTicket:学生票子类,继承父类Ticket

           学生票的折扣(Discount):int类型

           重写父类计算票价CalcPrice

           重写父类打印售票信息的Print()

           重写父类显示当前出票信息的Show()方法

         5.FreeTicket:赠票子类,继承父类Ticket

           获得赠票者的名字属性(CustomerName):string类型

           重写父类计算票价CalcPrice()

           重写父类打印售票信息Print()

           重写父类显示当前出票信息Show()

         6.ScheduleItem:影院每天计划放映计划的场次,保存每场电影的信息

           放映时间属性(Time):string类型

           本场所放映电影属性(Movie):Movie自定义类型

         7.Schedule:放映计划类

           放映场次属性(Items):自定义泛型集合Dictionary<string,ScheduleItem>

           读取XML文件获取放映计划集合的LoadItems()方法

         8.Cinema:影院类,保存放映计划和座位类

           座位集合属性(Seat):自定义泛型集合Dictionary<string,Seat>

           放映计划Schedule:Schedule自定义类型

           已售出电影票的集合(SoldTicket):自定义泛型集合List<Ticket>

           保存和读取售票情况的Save()和Load()方法

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

明天将继续更新-电影院座位的动态绘制、电影信息绑定到窗体中展现出来,也望各路大神出手斧正不合理的代码(不要涉及分层开发,我们在学,以后会用分层开发实现其他的项目)
