本文实例为大家分享了C#实现影院售票系统的具体代码，供大家参考，具体内容如下
本人认为此项目的难点有4点
1.首先是将解析完的XML文件绑定到TreeView上
2.用代码动态生成座位的label，生成触发事件Label_Click，俩组放映时间的售出座位是不同的
3.用序列化与反序列化实现代码的多次利用
4.打印票务
创建与本项目相关的10个类
一、首先在放映计划类中创建LoadItems()方法来解析ShowList.xml文件
XmlDocument dic=new XmlDocument();
dic.Load("ShowList.xml");
XmlNode xml = dic.DocumentElement;
foreach (XmlNode item in xml.ChildNodes)
{
Movie movie=new Movie();
movie.MovieName = item["Name"].InnerText;
movie.Poster = item["Poster"].InnerText;
movie.Director = item["Director"].InnerText;
movie.Actor = item["Actor"].InnerText;
movie.MovieType = (MovieType)(Enum.Parse(typeof(MovieType), item["Type"].InnerText));
movie.Price = Convert.ToInt32(item["Price"].InnerText);
//因为放映时间不在电影类中，所以经过第二次遍历，找到时间，最后将所有解析完的文件添加到Dic的双列集合中
foreach (XmlNode itemm in item["Schedule"])
{
ScheduleItem scheduleItem=new ScheduleItem();
scheduleItem.Time = itemm.InnerText;
scheduleItem.Movie = movie;
Dic.Add(scheduleItem.Time, scheduleItem);
二、将座位用代码填入放映厅中
int seatRow = 6;
int seatLine = 5;
for (int i = 0; i <seatRow; i++)
{
for (int j = 0; j < seatLine; j++)
{
label17 = new Label();
label17.BackColor = Color.Yellow;
label17.Font = new System.Drawing.Font("宋体", 14.25F, System.Drawing.FontStyle.Regular,
System.Drawing.GraphicsUnit.Point, ((byte) (134)));
label17.AutoSize = false;
label17.Size = new System.Drawing.Size(50, 25);
label17.Text = (j + 1).ToString() + "-" + (i + 1).ToString();
label17.TextAlign = ContentAlignment.MiddleCenter;
label17.Location=new Point(30+(i*90),30+(j*60));
label17
.Click += new System.EventHandler(lblseat_Click);
tabPage2.Controls.Add(label17);
list.Add(label17.Text,label17);
Seat seat=new Seat((j+1).ToString()+"-"+(i+1).ToString(),Color.Yellow);
cinema.Seats.Add(seat.SeatNum,seat);
}
}
利用双循环自动生成6行5列的座位表，其中将控件的大小和颜色以及位置进行固定
三、将解析完的文件绑定到Dic的集合中后再主窗体上进行绑定TreeView
Schedule s=new Schedule();
treeView1.BeginUpdate();
treeView1.Nodes.Clear();
string movieName = null;
TreeNode movieNode = null;
s.LoadItems();
foreach (KeyValuePair<string, ScheduleItem> item in s.Dic)
{
if (movieName!=item.Value.Movie.MovieName)
{
movieNode=new TreeNode(item.Value.Movie.MovieName);
treeView1.Nodes.Add(movieNode);
}
TreeNode timeNode=new TreeNode(item.Value.Time);
movieNode.Nodes.Add(timeNode);
movieName = item.Value.Movie.MovieName;
}
treeView1.EndUpdate();
之后的成功如下图所示
五、完成影片详情的绑定
将TreeView上的文件信息以单机的形式绑定到详情上
foreach (KeyValuePair<string, ScheduleItem> item in s.Dic)
{
if (treeView1.SelectedNode.Text==item.Key)
{
this.label2.Text = item.Value.Movie.MovieName;
this.label9.Text = item.Value.Movie.Director;
this.label10.Text = item.Value.Movie.Actor;
this.label11.Text = item.Value.Movie.MovieType.ToString();
this.label12.Text = item.Value.Time;
this.label13.Text = item.Value.Movie.Price.ToString();
this.pictureBox1.Image =Image.FromFile(item.Value.Movie.Poster);
this.label14.Text = "";
}
}
ClearSeat();
foreach (Ticket ticket in cinema.SoldTickets)
{
foreach (Seat seat in cinema.Seats.Values)
{
if ((ticket.ScheduleItem.Time == key) && (ticket.Seet.SeatNum == seat.SeatNum))
{
seat.Color = Color.Red;
}
}
}
UpdateSeat();
}
public void ClearSeat()
{
foreach (Seat seat in cinema.Seats.Values)
{
seat.Color = Color.Yellow;
}
}
分别利用序列化和反序列化的功能
序列化：save（）
public void Save()
{
FileStream fs = new FileStream("soldTickets.txt", FileMode.OpenOrCreate);
StreamWriter writer = new StreamWriter(fs, Encoding.Default);
for (int i = 0; i < SoldTickets.Count; i++)
{
Ticket ticket = SoldTickets[i];
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.Seet.SeatNum + "|" + ticket.Seet.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");
//MessageBox.Show("保存成功");
writer.Close();
fs.Close();
}
反序列化：Load（）
public void Load()
{
try
{
StreamReader reader = new StreamReader("soldTickets.txt", Encoding.GetEncoding("GB2312"));
string line = reader.ReadLine();
string[] propertyValues;
Ticket ticket = null;
while (line.Trim() != "The End")
{
propertyValues = line.Split('|');
string type = propertyValues[0];
Movie movie = new Movie(propertyValues[1], propertyValues[2], propertyValues[3], propertyValues[4],
(MovieType) Enum.Parse(typeof (MovieType), propertyValues[5]), int.Parse(propertyValues[6]));
ScheduleItem scheduleItem = new ScheduleItem();
scheduleItem.Time = propertyValues[7];
scheduleItem.Movie = movie;
string color = propertyValues[9];
string endColor = color.Substring(color.IndexOf("[") + 1, color.Length - 1 - color.IndexOf("[") - 1);
Seat seat = new Seat(propertyValues[8], Color.FromName(endColor));
int discount = 10;
switch (type)
{
case "student":
discount = 7;
ticket = TicketUitl.CreateTicket(scheduleItem, seat, "", Convert.ToInt32(discount), type);
break;
case "free":
discount = 0;
ticket = TicketUitl.CreateTicket(scheduleItem, seat, propertyValues[11],
Convert.ToInt32(discount), type);
break;
default:
discount = 10;
ticket = TicketUitl.CreateTicket(scheduleItem, seat, "", Convert.ToInt32(discount), "");
break;
}
this.SoldTickets.Add(ticket);
line = reader.ReadLine();
}
reader.Close();
}
catch (Exception ex)
{
Console.WriteLine("网络连接异常:" + ex.Message);
SoldTickets = new List<Ticket>();
throw;
}
}
以上则是本项目的多个难点的实现。
