影院售票系统（一）
现在学习到了C#的最后一本书，有一个窗体的结业案例。
- 先上图
运行起来是这样的
点击座位号弹出是否购票
买了之后座位变红色
对于老手来说可能so easy；但对我这菜鸟来说有点复杂，主要是面向对象思想与泛型集合的结合。
话不多说，先上类图
2.类介绍
其中包含了10个类
ticket电影票父类
//电影票父类
public class Ticket
{
//放映场次
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");
}
public Ticket()
{
}
public Ticket(ScheduleItem scheduleItem, Seat seat)
{
ScheduleItem = scheduleItem;
Seat = seat;
}
}
学生票子类
//学生票
public class StudentTicket:Ticket
{
//折扣
public int Discount { get; set; }
//计算票价
public override void CalcPrice()
{
Price = ScheduleItem.Movie.Price * Discount / 10;
}
//打印售票信息
public override 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 (学生) ");
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();
}
//显示售出票信息
public override void Show()
{
MessageBox.Show("已售出!\n\n " + Discount + "折学生票!");
}
public StudentTicket()
{
}
public StudentTicket(ScheduleItem scheduleItem, Seat seat, int discount)
: base(scheduleItem, seat)
{
Discount = discount;
}
}
免费票子类
public class FreeTicket:Ticket
{
public FreeTicket()
{
}
public FreeTicket(ScheduleItem scheduleItem, Seat seat, string customerName)
: base(scheduleItem, seat)
{
CustomerName = customerName;
}
//获赠者信息
public string CustomerName { get; set; }
//计算票价
public override void CalcPrice()
{
Price = 0;
}
//打印售票信息
public override 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 (赠票)");
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(" 姓名： \t{0}", CustomerName);
sw.WriteLine("***************************");
sw.Close();
fs.Close();
}
//显示售出票信息
public override void Show()
{
MessageBox.Show("已售出!\n\n 赠送者：" + CustomerName);
}
}
电影类
//电影类
public class Movie
{
//电影名
public string MovieName { get; set; }
//海报图片名
public string Poster { get; set; }
//导演名
public string Director { get; set; }
//主演名
public string Actor { get; set; }

}
public Movie(string movieName, string poster, string director, string actor, MovieType movieType, int price)
{
MovieName = movieName;
Poster = poster;
Director = director;
Actor = actor;
MovieType = movieType;
Price = price;
}
}
座位信息类
//座位类：保存座位信息
public class Seat
{
//座位号

//座位卖出状态颜色
public Color Color { get; set; }
public Seat() { }
public Seat(string seatnum,Color c)
{
this.SeatNum = seatnum;
this.Color = c;
}
}
放映计划类
这里包含了我注释掉的代码
//放映计划类
public class Schedule
{
public Schedule()
{
//放映场次属性
Items = new Dictionary<string, ScheduleItem>();
}
private Dictionary<string, ScheduleItem> items;
public Dictionary<string, ScheduleItem> Items
{
get
{
return items;
}
set
{
items = value;
}
}
//读取Xml文件的方法
public void LoadItems()
{
XmlDocument doc = new XmlDocument();
doc.Load(@"E:\c#\影院售票系统\影院售票系统\ShowList.xml");
XmlNode root = doc.DocumentElement;
foreach (XmlNode item in root.ChildNodes)
{
foreach (XmlNode child in item["Schedule"])
{
ScheduleItem sch = new ScheduleItem();
sch.Movie.MovieName = item["Name"].InnerText;
sch.Movie.Poster = item["Poster"].InnerText;
sch.Movie.Director = item["Director"].InnerText;
sch.Movie.Price = Convert.ToInt32(item["Price"].InnerText);
sch.Movie.Actor = item["Actor"].InnerText;
sch.Movie.MovieType = (MovieType)Enum.Parse(typeof(MovieType), item["Type"].InnerText);
sch.Time = child.InnerText;
items.Add(sch.Time, sch);
}
}
}
//读取xml文件获取放映计划集合的方法
/* public void LoadItems()
{
if (Items == null)
{
Items = new Dictionary<string, ScheduleItem>();
}
XmlDocument xml = new XmlDocument();
xml.Load(@"E:\c#\影院售票系统\影院售票系统\ShowList.xml");
XmlElement xe = xml.DocumentElement;
foreach(XmlNode xn in xe.ChildNodes)
{
ScheduleItem sc = new ScheduleItem();
Movie m = new Movie();
m.MovieName = xn["Name"].InnerText;
m.Poster=xn["Poster"].InnerText;
m.Diretor=xn["Director"].InnerText;
m.Actor=xn["Actor"].InnerText;
//foreach(MovieType mt in Enum.GetValues(typeof(MovieType)))
//{
//if (mt.ToString().Equals(xn["Type"].InnerText))
//{
m.MovieType=xn["Type"].InnerText;
// }
//}
m.Price=Convert.ToInt32(xn["Price"].InnerText);
sc.Movie = m;
foreach(XmlNode x in xn.ChildNodes)
{
if (x.Name == "Schedule")
{
sc.Time=x["Item"].InnerText;
}
}
Items.Add(m.MovieName,sc);
}
}

}
影院每天放映计划的场次，保存每场电影信息
//每天放映场次的计划
public class ScheduleItem
{
//放映时间属性
public string Time { get; set; }
//本场所放映电影属性
public Movie Movie { get; set; }
public ScheduleItem()
{
Movie = new Movie();
}
}
影院类
//影院类
public class Cinema
{
public Cinema()
{
Seats = new Dictionary<string, Seat>();
SoldTickets = new List<Ticket>();
Schedule = new Schedule();
}
public Dictionary<string, Seat> Seats;
//放映计划
public Schedule Schedule { get; set; }
//已售出电影票的集合
public List<Ticket> SoldTickets;
//保存售票情况
public void Save()
{
FileStream fs = new FileStream("soldTickets.txt", FileMode.OpenOrCreate);
StreamWriter writer = new StreamWriter(fs, Encoding.Default);
for (int index = 0; index < SoldTickets.Count; index++)
{
Ticket ticket = SoldTickets[index];
string info = "|" + ticket.ScheduleItem.Movie.MovieName + "|" + ticket.ScheduleItem.Movie.Poster + "|" +
ticket.ScheduleItem.Movie.Director + "|" + ticket.ScheduleItem.Movie.Actor + "|" + ticket.ScheduleItem.Movie.MovieType.ToString() + "|" +
ticket.ScheduleItem.Movie.Price + "|" + ticket.ScheduleItem.Time + "|" + ticket.Seat.SeatNum + "|" + ticket.Seat.Color + "|" + ticket.Price + "|";
if (ticket is FreeTicket)
{
string customerName = ((FreeTicket)ticket).CustomerName;
writer.WriteLine("free" + info + customerName);
}
else if (ticket is StudentTicket)
{
writer.WriteLine("student" + info + "");
}
else
{
writer.WriteLine("" + info + "");
}
}
writer.WriteLine("The End");
writer.Close();
fs.Close();
}
//读取售票情况
public void Load() {
try
{
//创建一个读取对象 //路径 //转换格式
StreamReader reader = new StreamReader("soldTickets.txt", Encoding.GetEncoding("GB2312"));
string line = reader.ReadLine();
//声明一个数组 存储 soldTickets.txt 的数据
string[] values;
//声明一个电影票对象
Ticket ticket = null;
while (line.Trim() != "The End")
{
values = line.Split('|');
string type = values[0];
Movie movie = new Movie(values[1], values[2], values[3], values[4], (MovieType)Enum.Parse(typeof(MovieType), values[5]), int.Parse(values[6]));
ScheduleItem scheduleItem = new ScheduleItem();
scheduleItem.Time = values[7];
scheduleItem.Movie = movie;
string color = values[9];
string endColor = color.Substring(color.IndexOf("[") + 1, color.Length - 1 - color.IndexOf("[") - 1);
Seat seat = new Seat(values[8], Color.FromName(endColor));
int discount = 10;
switch (type)
{
case "student":
discount = 7;
ticket = TicketUtil.CreateTicket(scheduleItem, seat, discount, "", type);
break;
case "free":
discount = 0;
ticket = TicketUtil.CreateTicket(scheduleItem, seat, discount, values[11], type);
break;
default:
discount = 10;
ticket = TicketUtil.CreateTicket(scheduleItem, seat, discount, "", "");
break;
}
this.SoldTickets.Add(ticket);
line = reader.ReadLine();
}
reader.Close();
}
catch (Exception ex)
{
Console.WriteLine("出错了:" + ex.Message);
SoldTickets = new List<Ticket>();
}
}
}
最后是工具类
//工具类
public class TicketUtil
{
//创建电影票的方法
public static Ticket CreateTicket(ScheduleItem item, Seat seat, int discount, string customer, string type)
{
Ticket ticket = null;
switch (type)
{
case "student":
ticket = new StudentTicket(item, seat, discount);
break;
case "free":
ticket = new FreeTicket(item, seat, customer);
break;
case "putong":
ticket = new Ticket(item, seat);
break;
}
return ticket;
}
}
