影院售票

做一个小程序(影院售票)

效果如下

主要功能有：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

影院提供三类票有不同的价位

主持购票，允许选座

系统可以保存销售情况并允许恢复

首先我们需要10个类（）具体关系如下

Seat类：保存影院座位信息  Movie：电影类         Ticket:电影父票类    StudentTickrt：学生子票类  FreeTicket：增票子类

ScheduItem：影院每天放映计划的场次   Cinema：影院类：保存放映计划和座位类  Tickuntli：工具类

主要功能一：实现座位的动态添加（代码如下）

  for (int i = 0; i < row; i++)
            {
                for (int j = 0; j < col; j++)
                {
                    Label lb = new Label();
                    lb.BackColor = Color.Yellow;
                    lb.Location = new Point(20 + j * 100, 50 + i * 70);
                    lb.Font = new Font("Courier New", 11);
                    lb.Name = (i + 1) + "-" + (j + 1);
                    lb.Size = new Size(80, 30);
                    lb.TabIndex = 0;
                    lb.Text = (i + 1) + "-" + (j + 1);
                    lb.TextAlign = ContentAlignment.MiddleCenter;
                    lb.Click += lb_Click;
                    tpCinema.Controls.Add(lb);
                    //添加座位对象到CInema的Seats集合中
                    Seat seat = new Seat(lb.Text, Color.Yellow);
                    cinema.Seats.Add(seat.SeatNum, seat);
                }
            }

效果如下：

功能二实现TreeView的绑定

首先需要解析XML文件(代码如下）

  //加载XML中的放映场次信息
        public void LoadItems()
        {
            try
            {
                XmlDocument doc = new XmlDocument();
                doc.Load(@"DataShowList.xml");
                XmlNode root = doc.DocumentElement;

                foreach (XmlNode var in root.ChildNodes)//Movie
                {
                    Movie movie = new Movie();
                    foreach (XmlNode var2 in var.ChildNodes)//Name
                    {
                        switch (var2.Name)
                        {
                            case "Name":
                                movie.MovieName = var2.InnerText;
                                break;
                            case "Poster":
                                movie.Poster = var2.InnerText;
                                break;
                            case "Director":
                                movie.Director = var2.InnerText;
                                break;
                            case "Actor":
                                movie.Actor = var2.InnerText;
                                break;
                            case "Price":
                                movie.Price = Convert.ToDouble(var2.InnerText);
                                break;
                            case "Type":
                                movie.MovieType = (MovieType)Enum.Parse(typeof(MovieType), var2.InnerText);
                                break;
                            case "Schedule":
                                foreach (XmlNode var3 in var2.ChildNodes)//Item
                                {
                                    ScheduleItem item = new ScheduleItem(movie, var3.InnerText);
                                    this.Items.Add(var3.InnerText, item);
                                }
                                break;
                        }
                    }
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
        }

然后在主窗体调用方法并且绑定(代码如下）

 this.tvMovies.Nodes.Clear();
            //加载XML
            cinema.Schedule.LoadItems();
            //绑定到TreeView
            TreeNode root = null;
            foreach (ScheduleItem var in cinema.Schedule.Items.Values)
            {
                if (root == null || root.Text != var.Movie.MovieName)
                {
                    //根节点
                    root = new TreeNode(var.Movie.MovieName);
                    this.tvMovies.Nodes.Add(root);
                }
                //子节点
                root.Nodes.Add(var.Time);
            }

效果如下

功能三具体信息的显示

  string time = this.tvMovies.SelectedNode.Text;
                ScheduleItem item = cinema.Schedule.Items[time];
                this.lblActor.Text = item.Movie.Actor;
                this.lblDirector.Text = item.Movie.Director;
                this.lblMovieName.Text = item.Movie.MovieName;
                this.lblPrice.Text = item.Movie.Price.ToString();
                this.lblTime.Text = item.Time;
                this.lblType.Text = item.Movie.MovieType.ToString();
                this.picMovie.Image = Image.FromFile(@"Image" + item.Movie.Poster);
                this.lblCalcPrice.Text = item.Movie.Price.ToString();

选择不同票时

   #region   点击普通票
        private void rdoNormal_CheckedChanged(object sender, EventArgs e)
        {
            this.cmbDisCount.Enabled = false;
            this.txtCustomer.Enabled = false;
            this.lblCalcPrice.Text = lblPrice.Text;
        } 
        #endregion
        #region    点击赠票
        private void rdoFree_CheckedChanged(object sender, EventArgs e)
        {
            this.txtCustomer.Enabled = true;
            this.cmbDisCount.Enabled = false;
            this.lblCalcPrice.Text = lblPrice.Text;
        } 
        #endregion
        #region  点击学生票
        private void rdoStudent_CheckedChanged(object sender, EventArgs e)
        {
            if (this.lblPrice.Text != "")
            {
                this.cmbDisCount.Enabled = true;
                this.txtCustomer.Enabled = false;
                this.lblCalcPrice.Text = (Convert.ToDouble(this.lblPrice.Text) * Convert.ToDouble(this.cmbDisCount.Text) / 10).ToString();
            }
        } 

售票功能

if (this.tvMovies.Nodes.Count == 0 || this.tvMovies.SelectedNode.Level == 0)
            {
                return;
            }

            lbl = sender as Label;
            if (lbl.BackColor == Color.Red)
            {
                MessageBox.Show("已售出");
            }
            else
            {
                if (DialogResult.OK == MessageBox.Show("是否购买", "提示", MessageBoxButtons.OKCancel, MessageBoxIcon.Question))
                {
                    //取得放映时间
                    string time = this.tvMovies.SelectedNode.Text;
                    //使用时间作为键找到放映场次对象
                    ScheduleItem item = cinema.Schedule.Items[time];
                    string type = string.Empty;
                    type = rdoNormal.Checked ? "normal" : rdoFree.Checked ? "free" : "student";
                    Ticket ticket = TicketUtil.CreateTicket(item, cinema.Seats[lbl.Text], txtCustomer.Text, Convert.ToDouble(cmbDisCount.Text), type);
                    //添加到已销售的集合中
                    cinema.SoldTickets.Add(ticket);
                    //出票
                    ticket.Print();
                    //更新颜色
                    lbl.BackColor = Color.Red;
                    cinema.Seats[lbl.Text].Color = Color.Red;
                }
            }

保存销售信息

  using (FileStream fs = new FileStream("student.dat",FileMode.Create))
            {
                BinaryFormatter bf = new BinaryFormatter();
                bf.Serialize(fs, SoldTickets);
            }

继续销售

  foreach (Seat seat in cinema.Seats.Values)
            {
                foreach (Label lbl in tpCinema.Controls)
                {
                    // 座位号相同证明是对应Label
                    if (lbl.Text == seat.SeatNum)
                    {
                        lbl.BackColor = seat.Color;
                    }
                }
            }

这个小程序还有很多不足
