範例

以下程式碼範例示範讓使用者按下按鈕就可以逐步將畫面旋轉成 ScreenOrientation 列舉中指定的各個方向。這個程式碼範例是 SystemSettings 類別完整範例的一部分。

' Each click event changes the screen orientation, as determined
' by the variable x, which increments from 0 to 3 and then back
' to 0. Four clicks cycle through the ScreenOrientation enumeration.
Private Sub Button1_Click(sender As Object, e As System.EventArgs) Handles Button1.Click

   Select Case x
      Case 0

         ' Pass a value for the ScreenOrientation enumeration
         ' to the SetOrientation method, defined below,
         ' and increment x so that the next button
         ' click rotates the screen orientation.
         SetOrientation(ScreenOrientation.Angle90)
         x += 1
      Case 1
         SetOrientation(ScreenOrientation.Angle180)
         x += 1
      Case 2
         SetOrientation(ScreenOrientation.Angle270)
         x += 1
      Case 3
         SetOrientation(ScreenOrientation.Angle0)
         x = 0
      Case Else
         SetOrientation(ScreenOrientation.Angle0)
         x = 0
   End Select
End Sub


' Set the orientation to a value of the
' ScreenOrienation enumeration and update the
' status bar with the current angle.
Private Sub SetOrientation(so As ScreenOrientation)
   ' Set the requested orientation.
   SystemSettings.ScreenOrientation = so

   Me.StatusBar1.Text = SystemSettings.ScreenOrientation.ToString()
End Sub

 // Each click event changes the screen orientation, as determined
 // by the variable x, which increments from 0 to 3 and then back

private void button1_Click(object sender, System.EventArgs e)
{

 switch(x)
 {
  case 0:

   // Pass a value for the ScreenOrientation enumeration
   // to the SetOrientation method, defined below,
   // and increment x so that the next button
   // click rotates the screen orientation.
   SetOrientation(ScreenOrientation.Angle90);
   x++;
   break;
  case 1:
   SetOrientation(ScreenOrientation.Angle180);
   x++;
   break;
  case 2:
   SetOrientation(ScreenOrientation.Angle270);
   x++;
   break;
  case 3:
   SetOrientation(ScreenOrientation.Angle0);
   x = 0;
   break;
  default:
   SetOrientation(ScreenOrientation.Angle0);
   x = 0;
   break;
 }
}

 // Set the orientation to a value of the
 // ScreenOrienation enumeration and update the
 // status bar with the current angle.
private void SetOrientation(ScreenOrientation so)
{
 // Set the requested orientation.

 SystemSettings.ScreenOrientation = so;

 this.statusBar1.Text = SystemSettings.ScreenOrientation.ToString();
}
