  private void button1_Click(object sender, EventArgs e)
        {
            for (int i = 0; i < 10; i++)
            {
                Panel pan = new Panel();
                pan.Width = 150;
                pan.Height = 150;
                pan.BackColor = System.Drawing.Color.Yellow;
                flowLayoutPanel1.Controls.Add(pan);

                PictureBox pic = new PictureBox();
                pic.Width = 150;
                pic.Height = 130;
                Image O_Image = Image.FromStream(WebRequest.Create("http://www.baidu.com/img/baidu_logo.gif").GetResponse().GetResponseStream());
                pic.Image = O_Image;
                pic.SizeMode = System.Windows.Forms.PictureBoxSizeMode.StretchImage;
                pan.Controls.Add(pic);

                CheckBox chk2 = new CheckBox();
                chk2.Width = 70;
                chk2.Text = "test" + i.ToString(); chk2.Checked = (i % 1 == 0); chk2.Visible = true;
                chk2.Top = 130;
                chk2.Width = 13; 
 
                pan.Controls.Add(chk2);

                Label lab = new Label();
                lab.Text = "lab" + i.ToString();
                lab.Top = 130;
                lab.Left = 15;
                pan.Controls.Add(lab);

            }

代码如上，checkbox放在pannel中 pannel放在flowLayoutPanel中，如何获取选中checkbox的文本？

帮忙看下这个全选和取消代码怎么不好用？flowLayoutPanel1.Controls是不是不能获取到panel中的控件？

private void checkBox1_CheckedChanged(object sender, EventArgs e)
        {
            {
                CheckBox all = sender as CheckBox;
                foreach (Control ctl in flowLayoutPanel1.Controls)
                {
                    if (ctl is CheckBox)
                    {
                        CheckBox chk = ctl as CheckBox;
                        chk.Checked = all.Checked;
                    }
                }
            }
        }

[解决办法]
全选全不选
private void checkBox1_CheckedChanged(object sender, EventArgs e)
{
CheckBox all = sender as CheckBox;
foreach (Control ctl in flowLayoutPanel1.Controls)
{
if (ctl is Panel)
{
Panel p = ctl as Panel;
foreach (var ss in p.Controls)
{
if ((ss as CheckBox) is CheckBox)
{
if ((ss as CheckBox).Checked)
{
(ss as CheckBox).Checked = false;
}
else
{
(ss as CheckBox).Checked = true;

}
}
else
{

}
}
}
}
}
