请教:泛型类 可以被序列化吗?
请教老师达人:泛型类 可以被序列化吗?

比如:

[Serializable]
class S<T>
{
   int a = 0;
    void count ()
  {
    a = a+1
    Console.Write (a);
    Console.Read();
  }
 .........
}


S<int> a=new S<int>();
Stream steam = File.Open(filename, FileMode.Create);
BinaryFormatter bf = new BinaryFormatter();
bf.Serialize(steam,a);
steam.Close();

======================
这样行吗?

可以的,泛型在编译时就已经被变成具体的类了。

授人以渔,不授人以鱼。

泛型类可以被序列化、但前提是泛型参数可以序列化时。

你的程序是可以的所谓的序列化类、不过就是序列化参数
如:
S<int> a=new S<int>();
Stream steam = File.Open(filename, FileMode.Create);
BinaryFormatter bf = new BinaryFormatter();
bf.Serialize(steam,a);

下面的代码 在表示层用 TabControl  -  TabPage  - 里面用 Lable 来 模拟 影院 生成的座位。

请教老师大侠,如何序列化保存生成的座位,以便在下次运行时可以看到所生成的座位?

可以做成“泛型类”-- 也就是说把 private void InitSeats(TabPage tp )下的代码和private void lblSeat_Click(object sender, EventArgs e) 下的代码全部放在“泛型类”中,然后实例化对象 ---- 然后序列化这个泛型类对象,可以吗?

拜谢老师先!!!

=====================================
namespace MyTest
{
    public partial class FrmSeat : Form
    {
        public FrmSeat()
        {
            InitializeComponent();
         

        }

      

        private void InitSeats(TabPage tp )
        {
            //用Label控件来表示座位
            Label label;

            //清空Label
            tp.Controls.Clear();


            int line;
            int column;
            //if (txtLine.Text.Trim() !="" && txtColumn.Text.Trim() != "")
            //{
                //行
                line = Convert.ToInt32(txtLine.Text.Trim());
                //列
                column = Convert.ToInt32(txtColumn.Text.Trim());
            //}

            
            for (int i = 0; i < line; i++)
            {
                for (int j = 0; j <= column; j++)
                {
                    label = new Label();
                    //设置背景颜色
                    label.BackColor = Color.Orange;
                    //设置尺寸
                    label.AutoSize = false;
                    label.Size = new System.Drawing.Size(35, 15);
                    //设置座位号
                    label.Text = (i + 1).ToString() + "-" + (j + 1).ToString();
                    label.TextAlign = ContentAlignment.MiddleCenter;
                    //设置边距位置
                    label.Location = new Point(50 + j * 38, 50 + (i * 25));
                    //所有的标签都绑定到同一事件
                    label.Click += new System.EventHandler(lblSeat_Click);
                    //添加Label
                    tp.Controls.Add(label);
                }
            }
        }


        private void lblSeat_Click(object sender, EventArgs e)
        {
            if (((Label)sender).BackColor == Color.Red)
            {
                MessageBox.Show("此票已经卖出:" + ((Label)sender).Text.ToString(), "提示");
                return;
            }
            MessageBox.Show("选择了:" + ((Label)sender).Text.ToString(), "提示");
            //修改座位的颜色
            ((Label)sender).BackColor = Color.Red;
        }


        

        private void FrmSeat_Load(object sender, EventArgs e)
        {
            this.txtLine.Text = null;
            this.txtColumn.Text = null;

        }

        private void btnCreatSeat_Click(object sender, EventArgs e)
        {


            InitSeats(tpCinema);


        }

      

        private void tpCinema_Click_1(object sender, EventArgs e)
        {

        }

    }

}

我是这样做的“泛型类”--- 然后序列化 这个“泛型类” + 反序列化。

1)但是运行时报错: private void FrmSeat_Load(object sender, EventArgs e) 里的 ReadSeat()下面出现红线,
提示:“当前上下文中不存在名称为“ReadSeat()””

可是这个“ReadSeat()” 明明就在上面呀,到底哪出错了呢?

2) 我这样做对吗?

求老师大侠指教,多谢了!!!
