在通用Windows应用中获取键盘状态 [英] Get Keyboard state in Universal Windows Apps

问题描述

我想在Windows应用中检测一个组合键（例如 Control-A ）。 KeyDown 事件处理程序具有有关最后按下的键的信息。但是，如何确定是否也按下了Control键？

I want to detect a key combination (e.g. Control-A) in a Windows App. The KeyDown event handler has information about the last key pressed. But how do I find out whether the Control key is pressed as well?

推荐答案

您可以使用 CoreVirtualKeyStates.HasFlag（CoreVirtualKeyStates.Down）来确定是否已按下 Ctrl 键，例如-

You can use CoreVirtualKeyStates.HasFlag(CoreVirtualKeyStates.Down) to determine is the Ctrl key has been pressed, like this -

Window.Current.CoreWindow.KeyDown += (s, e) =>
{
    var ctrl = Window.Current.CoreWindow.GetKeyState(VirtualKey.Control);
    if (ctrl.HasFlag(CoreVirtualKeyStates.Down) && e.VirtualKey == VirtualKey.A)
    {
        // do your stuff
    }
};
