影院售票系统-----一个让你有成就感的小项目，只有一丢丢哦
先来点废话，刚拿到这个项目的时候你是怎么想的，上来就闷头写，还是构想思路......
项目需求：
影院售票系统可以销售每天不同时段的电影票，不同时段的电影票有不同的优惠政策，还有使用兑换券的免费票。选择某个时段的一场电影，
单击放映厅未售出的座位并选择一个种类的电影票，创建电影票，计算价格并打印，座位设置为红色表示已经售出。
思想：
使用面向对象思想编写影院售票系统
看完这个你有没有点思路呢，我想你是有的 ......
下面先来点图片，先刺激一下视觉：
窗体搭建：
程序运行时发生的，来看清楚了：
是不是该选择你要看的电影列表了
好了，该你选择电影了，
挑选你喜欢的座位:
掏钱吧，要不你选择的就是别人的了
这个座位是你的了，还想看别的么？
选择赠票吧，免费的：
再来张学生票：
这样看是不是特别不爽，我感觉也是，看图片没感觉，接下来代码吧！
先把我们所需要的几个类创建出来吧！
/// <summary> /// 电影票父类 /// </summary> public class Ticket { public Ticket() { } public Ticket(ScheduleItem scheduleItem, Seat seat) { ScheduleItem = scheduleItem; Seat = seat; } //播放场次 public ScheduleItem ScheduleItem { get; set; } //所属座位对象 public Seat Seat { get; set; } //票价 public int Price { get; set; } //计算票价的虚方法 public virtual void CalcPrice() { Price =ScheduleItem.Movie.Price; } //打印售票信息的虚方法 public virtual void Print() { string fileName = ScheduleItem.Time.Replace(":", "-") + " " + Seat.SeatNum + ".txt"; FileStream fs = new FileStream(fileName, FileMode.Create); StreamWriter sw = new StreamWriter(fs); sw.WriteLine("***************************"); sw.WriteLine(" 青鸟影院(普通) "); sw.WriteLine("---------------------------"); sw.WriteLine(" 电影名：\t{0}", ScheduleItem.Movie.MovieName); sw.WriteLine(" 时间： \t{0}", ScheduleItem.Time); sw.WriteLine(" 座位号：\t{0}", Seat.SeatNum); sw.WriteLine(" 价格： \t{0}", Price.ToString()); sw.WriteLine("***************************"); sw.Close(); fs.Close(); } //显示当前售出票信息的虚方法 public virtual void Show() { MessageBox.Show("已售出"); } }

我去，这么多类，你有没有这个感觉，反正我是有的，这些类的创建不是瞎弄的，要把自己的思路理清楚了！

这没有多少文字解说，思想在其中。
其实写这些都是枯燥的，但是写完的那一刻，运行的那一刻，你就会觉得这些都是值得的，虽然这是一个特小的项目。
人的信心就是从一点一滴积累起来的，我是这样告诉自己的，不要局限自己，编程是思想，不是Copy!
希望我的文章能给你提供一种方法，而不是让你作弊！
要想人前显贵，就要背后受罪，我觉得说的真好！啰嗦了，我只是想提醒自己！
