怎么在这段代码运行效果是这样的啊？能帮我改改吗？

[zhangliangxinyue]

public Form1()
{
InitializeComponent();
}
ArrayList list = new ArrayList();

private void Form1_Load(object sender, EventArgs e)
{
list.Add(this.panel1);
list.Add(this.panel2);
list.Add(this.panel3);
list.Add(this.panel4);
list.Add(this.panel5);
list.Add(this.panel6);
list.Add(this.panel7);
list.Add(this.panel8);


for (int i = 0; i < 8; i++)
{

dd = i.ToString();
Panel p = (Panel)list[i];
p.Paint+=new PaintEventHandler(p_Paint);


}

}
string dd = "";
private void p_Paint(object sender, PaintEventArgs e)
{

Panel p = (Panel)sender;
Graphics g = p.CreateGraphics();

System.Drawing.SolidBrush drawBrush = new System.Drawing.SolidBrush(System.Drawing.Color.Black);
System.Drawing.StringFormat drawFormat = new System.Drawing.StringFormat();
Font drawFont = new Font(FontFamily.GenericMonospace, 10, FontStyle.Bold);
g.DrawString(dd, drawFont, drawBrush, 0, 10, drawFormat);



}

这段代码运行怎么每个面板上全是7啊
不是每个面板上分别是1234567吗？？？？？
怎么修改才能达到这个效果啊？？？？？？？
急急急啊？？？？？？？？

        ArrayList list = new ArrayList();

        private void Form1_Load(object sender, EventArgs e)
        {
            list.Add(this.panel1);
            list.Add(this.panel2);
            list.Add(this.panel3);
            list.Add(this.panel4);
            list.Add(this.panel5);
            list.Add(this.panel6);
            list.Add(this.panel7);
            list.Add(this.panel8);


            for (int i = 0; i < 8; i++)
            {
                Panel p = (Panel)list[i];
                p.Tag = i.ToString();
                p.Paint += new PaintEventHandler(p_Paint);
            }
        }

        private void p_Paint(object sender, PaintEventArgs e)
        {
            Panel p = (Panel)sender;
            Graphics g = p.CreateGraphics();

            System.Drawing.SolidBrush drawBrush = new System.Drawing.SolidBrush(System.Drawing.Color.Black);
            System.Drawing.StringFormat drawFormat = new System.Drawing.StringFormat();
            Font drawFont = new Font(FontFamily.GenericMonospace, 10, FontStyle.Bold);
            g.DrawString(p.Tag.ToString(), drawFont, drawBrush, 0, 10, drawFormat);
        }

“p.Tag = i.ToString();”

。。。 路过。

[luhao0725]

for (int i = 0; i < 8; i++)
{

dd = i.ToString();
Panel p = (Panel)list[i];
p.Paint+=new PaintEventHandler(p_Paint);


}
循环给一个变量赋值当然出来后就是最后一个值了;
用楼上的方法应该可以,也可以改成下面的方法,我试过了是可以的:

ArrayList list = new ArrayList();

        private void Form1_Load(object sender, EventArgs e)
        {
            list.Add(this.panel1);
            list.Add(this.panel2);
            list.Add(this.panel3);
            list.Add(this.panel4);
            list.Add(this.panel5);
            list.Add(this.panel6);
            list.Add(this.panel7);
            list.Add(this.panel8);


            for (int i = 0; i < 8; i++)
            {
                Panel p = (Panel)list[i];
                p.Paint += new PaintEventHandler(p_Paint);
            }
        }

        private void p_Paint(object sender, PaintEventArgs e)
        {
            Panel p = (Panel)sender;
            Graphics g = p.CreateGraphics();

            System.Drawing.SolidBrush drawBrush = new System.Drawing.SolidBrush(System.Drawing.Color.Black);
            System.Drawing.StringFormat drawFormat = new System.Drawing.StringFormat();
            Font drawFont = new Font(FontFamily.GenericMonospace, 10, FontStyle.Bold);
            g.DrawString(list.IndexOf(sender).ToString(), drawFont, drawBrush, 0, 10, drawFormat);
        }
