 一：影院的基本框架

 

 

 

 需要的类图：

二：实现效果：

绑定treeview，解析xml

 实现绑定TreeView：
 public void Bingding()
        {
            items = new Schedule();
            items.LoadItem();
            cinema.Schedule = items;
            string name = null;
            TreeNode tr = null;
            foreach (KeyValuePair<string, Scheduleltem> item in cinema.Schedule.items)
            {
                if (name != item.Value.Movie.MovieName)
                {

                    tr = new TreeNode();
                    tr.Text = item.Value.Movie.MovieName;
                    tvMovies.Nodes.Add(tr);

                }
                tr.Nodes.Add(item.Key);
                name = item.Value.Movie.MovieName;
            }

 

 解析xml：
 public void LoadItem() 
        {

            XmlDocument doc = new XmlDocument();
            doc.Load("ShowList.xml");
            XmlNode root = doc.DocumentElement;
            foreach (XmlNode item in root.ChildNodes)
            {
                Movie Movie = new Movie();
                 Movie.MovieName = item["Name"].InnerText;
                 Movie.Poster = item["Poster"].InnerText;
                 Movie.Director = item["Director"].InnerText;
                 Movie.Price =Convert.ToInt32( item["Price"].InnerText);
                 Movie.Actor = item["Actor"].InnerText;
                 Movie.MovieType = MovieType.Action;
                 foreach (XmlNode item1 in item["Schedule"].ChildNodes)
                 {
                     Scheduleltem sch = new Scheduleltem();
                     sch.Movie = Movie;
                     sch.Time = item1.InnerText;
                     items.Add(sch.Time, sch);


                 }

 

点击时间将影片的信息进行传值

            TreeNode node = tvMovies.SelectedNode;
            if (node == null) return;
            if (node.Level != 1) return;
            key = node.Text;
            if (tvMovies.SelectedNode.Level > 0)
            {
                this.lblMovieName.Text = cinema.Schedule.items[key].Movie.MovieName;

                this.lblDirector.Text = cinema.Schedule.items[key].Movie.Director;
                this.lblActor.Text = cinema.Schedule.items[key].Movie.Actor;
                this.lblPrice.Text = cinema.Schedule.items[key].Movie.Price.ToString();
                this.lblTime.Text = cinema.Schedule.items[key].Time;
                this.lblType.Text = cinema.Schedule.items[key].Movie.MovieType.ToString();
                this.picMovie.Image = Image.FromFile(cinema.Schedule.items[key].Movie.Poster);
                this.lblCalcPrice.Text = "";

 遍历座位的方法：

 private void initseats()
        {
            Label label;
            Seat seat;
            int num = 5;//定义列
            int num1 = 7;//定义行
            for (int i = 0; i < num1; i++)
            {
                for (int j = 0; j < num; j++)
                {
                    Label lab = new Label();
                    lab.BackColor = Color.Yellow;
                    lab.Font = new System.Drawing.Font("宋体", 14.25F);
                    lab.Size = new System.Drawing.Size(50, 20);
                    //坐位号
                    lab.Text = (j + 1).ToString() + "-" + (1 + i).ToString();
                    //字体居中
                    lab.TextAlign = ContentAlignment.MiddleCenter;
                    //设置位置
                    lab.Location = new Point(40 + (i * 90), 50 + (j * 60));
                    //所有的标签都绑定到同一事件
                    lab.Click += new System.EventHandler(lblSeat_Click);
                    tpCinema.Controls.Add(lab);
                    tpCinema.Controls.Add(lab);
                    //实例化一个座位
                   seat = new Seat((j+1).ToString()+"-"+(i+1).ToString(),Color.Yellow);
                    //保存座位的集合
                    cinema.Seats.Add(seat.SeatNum,seat);
                    lab.Click += lab_Click;
                    labels.Add(lab.Text,lab);
                }
            }

        }
注意：用的方法写的 要记住调用方法

选择不同的票的方法是：有些的方法是禁用的 即为显示的为不能写的列表

        private void rdoFree_CheckedChanged(object sender, EventArgs e)
        {
            if (rdoNormal.Checked == true)
            {
                this.label12.Enabled = false;
                this.label13.Enabled = false;
                this.cmbDisCount.Enabled = false;
                this.txtCustomer.Enabled = false;
                this.cmbDisCount.SelectedIndex = -1;
            }
            else if (rdoFree.Checked == true)
            {
                this.label12.Enabled = false;
                this.cmbDisCount.Enabled = false;
                this.txtCustomer.Enabled = true;
                this.label13.Enabled = true;
                this.cmbDisCount.SelectedIndex = -1;
            }
            else if (rdoStudent.Checked == true)
            {
                this.label13.Enabled = false;
                this.txtCustomer.Enabled = false;
                this.label12.Enabled = true;
                this.cmbDisCount.Enabled = true;
                this.cmbDisCount.SelectedIndex = 0;
            }

        }

                   

                      

 

 

 

 

 

         

  在选中座位时，既有座位的时候点击保存，退出程序，再一次点击购票，点击继续销售，返回你当初订电影票的时候所选中的电影票，就会发现上次所选中的票依然还在，  点击获取新放映列表的时候会重新订票 依然不显示已经订票的结果 会重新刷列表

点击保存的时候会显示是否刷新保存当前的内容

 private void tsmiSave_Click(object sender, EventArgs e)
        {
            DialogResult result = MessageBox.Show("是否保存当前销售状态？", "操作提示", MessageBoxButtons.YesNo, MessageBoxIcon.Question);
            if (result == DialogResult.Yes)
            {
                //退出时序列化Cinema对象
                cinema.laod();
            }

        }
