Property Value

ModifierKeys

ModifierKeys 值的位元組合。A bitwise combination of the ModifierKeys values.

Examples

下列範例會使用一點和比較來判斷是否按下 Control 輔助按鍵。The following example uses a bit AND comparison to determine if the Control modifier key is pressed.

if ((Keyboard.Modifiers & ModifierKeys.Control) > 0)
{
    button1.Background = Brushes.Red;
}
else
{
    button1.Background = Brushes.Blue;
}
If (Keyboard.Modifiers And ModifierKeys.Control) > 0 Then
    button1.Background = Brushes.Red
Else
    button1.Background = Brushes.Blue
End If

Remarks

ModifierKeys 是位欄位列舉,因此可以同步選取多個輔助按鍵。ModifierKeys is a bit field enumeration, so it is possible for multiple modifier keys to be pressed at the same time. 使用位運算來判斷所按下的一組完整的輔助按鍵。Use bit operations to determine the exact set of modifier keys pressed.
