asp教程.net 生成控件后自动获取控件的name值
//用控件的tag属性比较方便

private void message(object sender,eventargs e)
{
      picturebox pic = sender as picturebox;
      string lblname=((label)pic.tag).name;
      messagebox.show(lblname);
}
//动态生成控件时,指定name,然后找到它:

foreach (control ct in form1.controls)
            {
                //c# 只遍历窗体的子控件,不遍历孙控件
                //当窗体上的控件有子控件时,需要用递归的方法遍历,才能全部列出窗体上的控件
                if (ct.name=="")
                {
                   
                }
            }
        }

//实例

 picturebox p = new picturebox();
                    p.name = "p" + i.tostring();
                    p.sizemode = system.windows.forms.pictureboxsizemode.stretchimage;
                    p.imagelocation = @"d:www.111com.nethome4.png";
                    p.size = new system.drawing.size(60, 60);
                    p.location = new system.drawing.point(5 * 17 * i-60, 50);
                    p.cursor = system.windows.forms.cursors.hand;
                    p.doubleclick += new eventhandler(message);
                    p.mousemove += new system.windows.forms.mouseeventhandler(this.mouseo教程ver);
                    p.mouseleave += new system.eventhandler(this.mouseo教程ut);
                    p.contextmenustrip = contextmenustrip1;
                    this.sp_l_r.panel2.controls.add(p);
                    label la = new label();
                    la.name = "la" + i.tostring();
                    la.text = "0000";
                    la.location = new system.drawing.point(50, 120);
                    this.sp_l_r.panel2.controls.add(la);
