打开和关闭面板

Question

基本上我正在制作电梯，我已经将机芯功能降下来，但现在我需要让它们打开和关闭。我尝试过一些东西，但似乎无法让它发挥作用。

按钮代码

private void CP_GFButton_Click(object sender, EventArgs e)
        {
            while (LDoor.Location.Y < 350)
                while (Rdoor.Location.Y < 350)
                {
                    LDoor.Location = new System.Drawing.Point(LDoor.Location.X, LDoor.Location.Y + 1);  //Move Left Door DOWN
                    System.Threading.Thread.Sleep(10);

                    Rdoor.Location = new System.Drawing.Point(Rdoor.Location.X, Rdoor.Location.Y + 1); // Move Right door DOWN
                    System.Threading.Thread.Sleep(10);
                }
        }

        private void CP_OneFbutton_Click(object sender, EventArgs e)
        // Move both lift doors up
        {
            while (LDoor.Location.Y > 90)
                while (Level1.Location.Y > 90)
                    while (Rdoor.Location.Y > 90)
                    {
                        LDoor.Location = new System.Drawing.Point(LDoor.Location.X, LDoor.Location.Y - 4);  // Move Left door UP
                        System.Threading.Thread.Sleep(10);

                        Rdoor.Location = new System.Drawing.Point(Rdoor.Location.X, Rdoor.Location.Y - 4); //Move Right door UP
                        System.Threading.Thread.Sleep(10);

                        Level1.Location = new System.Drawing.Point(Level1.Location.X, Level1.Location.Y - 4); //Move Right door UP
                        System.Threading.Thread.Sleep(10);

                    }
        }

尝试过的代码：

while (LDoor.Width > 5)
{
  LDoor.Width--;
  LDoor.Width--;
  LDoor.Location = new Point(LDoor.Left + 1, LDoor.Top);
}
