首先，是主窗体的搭建。

   using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows.Forms; namespace 影院售票系统 { public partial class FrmMain : Form { public FrmMain() { InitializeComponent(); } Cinema cinema = new Cinema(); Dictionary<string, Label> lables = new Dictionary<string, Label>(); int ticket = 0;

string customerName = this.textBox1.Text.ToString(); int discount = 0; string type = ""; if (this.radioButton3.Checked) { type = "student"; if (this.comboBox1.Text == null) { MessageBox.Show("请输入折扣数", "提示");

其次，六个类的建立，

以及XML文件的解析。 using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Xml; namespace 影院售票系统 { public class Schedule { public Dictionary<string, ScheduleItem> Items = new Dictionary<string, ScheduleItem>(); public Schedule() { Items = new Dictionary<string, ScheduleItem>(); } public void LoadItems() { if (Items == null) Items = new Dictionary<string, ScheduleItem>(); Items.Clear(); XmlDocument myXml = new XmlDocument(); myXml.Load("ShowList.xml"); XmlNode feednode = myXml.DocumentElement; //中间变量 string movieName = null; string playBill = null; string director = null; string actor = null; string movieType = null; string price = null; foreach (XmlNode node in feednode.ChildNodes) { if (node.Name == "Movie") { foreach (XmlNode subNode in node.ChildNodes) { switch (subNode.Name) { case "Name": movieName = subNode.InnerText; break; case "Poster": playBill = subNode.InnerText; break; case "Director": director = subNode.InnerText; break; case "Actor": actor = subNode.InnerText; break; case "Type": movieType = subNode.InnerText; break; case "Price": price = subNode.InnerText; break; case "Schedule": foreach (XmlNode scheduleNode in subNode.ChildNodes) { ScheduleItem item = new ScheduleItem(); item.Time = scheduleNode.InnerText; item.Movie.MovieName = movieName; item.Movie.Poster = playBill; item.Movie.Director = director; item.Movie.Actor = actor; item.Movie.MovieType = (MovieType) Enum.Parse(typeof (MovieType), movieType); item.Movie.Price = int.Parse(price); Items.Add(item.Time, item); } break; } } } } } } }     打印售票信息： using System; using System.Collections.Generic; using System.IO; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows.Forms; namespace 影院售票系统 { public class StudentTicket:Ticket { public int Discount { get; set; } public StudentTicket(ScheduleItem scheduleitem, Seat seat, int discount) : base(scheduleitem, seat) { this.Discount = discount; } public override void CalcPrice() { this.Price = this.ScheduleItem.Movie.Price * Discount / 10; } public override void Print() { string fileName = this.ScheduleItem.Time.Replace(":", "-") + " " + this.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}", this.ScheduleItem.Movie.MovieName); sw.WriteLine(" 时间： \t{0}", this.ScheduleItem.Time); sw.WriteLine(" 座位号：\t{0}", this.Seat.SeatNum); sw.WriteLine(" 价格： \t{0}", this.Price.ToString()); sw.WriteLine("***************************"); sw.Close(); fs.Close(); } public override void Show() { MessageBox.Show("已售出!\n\n" + this.Discount + "折学生价"); } } }
