首先，我需要明确表示我对键盘记录没有兴趣.
First of all I need to make it clear that I have no interest in keylogging.
当我的应用程序在后台运行时，我需要一种方法来监控最基本的键盘活动.我不需要知道哪些键，我不需要保存任何数据，我根本不需要或不打算隐藏我的应用程序，我只需要知道何时按下键并调用方法.
I need a way to monitor keyboard activity at the most basic level while my application is in the background. I don't need to know which keys, I don't need to save any data, I don't need or plan to hide my application at all, all I need is to know when keys are pressed and invoke a method.
我正在寻找最简单的方法来做到这一点，我知道相当数量的 C#，但没有什么太复杂的，因为我的大部分知识都是自学的.
I'm looking for the simplest way to do this possible, I know a reasonable amount of C# but nothing too complex as most of my knowledge is self-taught.
我环顾四周寻找一些合适的方法，但没有发现任何有用的方法.我只发现一堆人在论坛和深度键盘记录器的源代码上说不，那是非法的".
I've looked around for some appropriate ways of doing this and I've found nothing useful. All I've found is a bunch of people saying "No, that's illegal" on forums and source code for in depth keyloggers.
如果你们中的任何人能就实现这一目标的方法向我提出建议，那么我将不胜感激.
If any of you could advise me on a way to achieve this then I would be most appreciative.
