Question

我有以下代码：

public void tbSpeed_KeyDown(object sender, KeyRoutedEventArgs e)
{
    e.Handled = !((e.Key >= 48 && e.Key <= 57) || (e.Key >= 96 && e.Key <= 105) || (e.Key == 109) || (e.Key == 189));
}

有没有办法检测是否有任何像Shift这样的修饰键？？

Answer 1

使用GetKeyState。 e.g。

var state = CoreWindow.GetForCurrentThread().GetKeyState(VirtualKey.Shift);
return (state & CoreVirtualKeyStates.Down) == CoreVirtualKeyStates.Down;

注意：对于Alt，您可以使用VirtualKey.Menu。

Answer 2

对于Win10 UWP，我注意到CTRL和SHIFT键设置为Locked状态。所以我做了以下事情：

var shiftState = CoreWindow.GetForCurrentThread().GetKeyState(VirtualKey.Shift);
var ctrlState = CoreWindow.GetForCurrentThread().GetKeyState(VirtualKey.Control);

var isShiftDown = shiftState != CoreVirtualKeyStates.None;
var isCtrlDown = ctrlState != CoreVirtualKeyStates.None;

Answer 3

您可以尝试以下代码

CoreVirtualKeyStates controlKeyState = Window.Current.CoreWindow.GetKeyState(VirtualKey.Control);
var  ctrl = (controlKeyState & CoreVirtualKeyStates.Down) == CoreVirtualKeyStates.Down;

CoreVirtualKeyStates shiftKeyState = Window.Current.CoreWindow.GetKeyState(VirtualKey.Shift);
var shift = (shiftKeyState & CoreVirtualKeyStates.Down) == CoreVirtualKeyStates.Down;

Bitwise AND键盘的Modifiers属性与Shift键 -

bool isShiftKeyPressed = (Keyboard.Modifiers & ModifierKeys.Shift)
                         == ModifierKeys.Shift;

试试这个 -

bool isShiftKeyPressed = (ModifierKeys & Keys.Shift) == Keys.Shift;

OR

Control.ModifierKeys == Keys.Shift

检测KeyRoutedEventArgs事件中是否按下了修改键
