C# winfrom动态生成panel面板，移动有蒙版和按钮显隐

public static int jj=4;
public static string[,] Chess = new string[jj, 3]; //声明一个二维数组.
//1.面板名
//2.button名
//3.显隐

小面板中

  private void panel_MouseEnter(object sender, EventArgs e)
        {
            Panel panel2 = (Panel)sender;

            for (int i = 0; i < jj; i++)
            {
                Button button = panel1.Controls.Find(Chess[i, 1], true)[0] as Button;
                Panel panel = panel1.Controls.Find(Chess[i, 0], true)[0] as Panel;
               
                if (Chess[i, 0].ToString() == panel2.Name.ToString())
                {
                   if(Chess[i, 2].ToString()=="0")
                        {
                       
                        button.Visible = true;
                        panel.BackColor = Color.AntiqueWhite;
                    }
                }
            }
          
        }

最外部的面板

 private void panel1_MouseEnter(object sender, EventArgs e)
        {
            for (int i = 0; i < jj; i++)
            {
                Button button = panel1.Controls.Find(Chess[i, 1], true)[0] as Button;
                Panel panel = panel1.Controls.Find(Chess[i, 0], true)[0] as Panel;

                panel.BackColor = Color.Transparent;
                button.Visible = false;
            }
        }
