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));
}
解决方法
使用
GetKeyState.
var state = CoreWindow.GetForCurrentThread().GetKeyState(VirtualKey.Shift); return (state & CoreVirtualKeyStates.Down) == CoreVirtualKeyStates.Down;
注意：对于Alt,您将使用VirtualKey.Menu.
