如何在表格之外捕获按键? [英] How can I capture a key press, outside of the form?

问题描述

我一直试图捕获在Winform外部按下的键，但是显然KeyPress事件不起作用.

I have been trying to capture the keys pressed outside of my winform, but obviously a KeyPress event won't work.

我没有比KeyPress事件更近的地方，该事件仅在指定的表单级别起作用

I haven't been able to get any closer than the KeyPress event, which only works on the form level, as specified

我怀疑我将不得不做

[DllImportAttribute("user32.dll")]

[DllImportAttribute("user32.dll")]

，但是我对此几乎没有经验.

, but I have little to no experience with that.

推荐答案

要在任何地方捕获按键，都需要使用

Being able to capture key presses anywhere requires using Hooks.
