向下移動一個對象，C＃

Question

我有一個向上移動對象的按鈕。我只是想知道我有什麼改變，使其向下移動（不同的按鈕）

private void CP_GFButton_Click(object sender, EventArgs e) 
     { 
      while (LDoor.Location.Y < 0) 
       while (Rdoor.Location.Y < 0) 
       { 
        LDoor.Location = new System.Drawing.Point(LDoor.Location.X, LDoor.Location.Y - 1); 
        System.Threading.Thread.Sleep(10); 

        Rdoor.Location = new System.Drawing.Point(Rdoor.Location.X, Rdoor.Location.Y - 1); 
        System.Threading.Thread.Sleep(10); 
       } 
     } 

Answer 1

 while (LDoor.Location.Y < MaxVal) 
      while (Rdoor.Location.Y < MaxVal) 
      { 
       LDoor.Location = new System.Drawing.Point(LDoor.Location.X, LDoor.Location.Y + 1); 
       System.Threading.Thread.Sleep(10); 

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