C#Mono-低级键盘钩 [英] C# Mono - Low Level Keyboard Hook

问题描述

我使用的是在 CodeProject.com上找到的代码，水平键盘挂钩.唯一的问题是，它使用的外部DLL调用在mono中不起作用.我想知道是否有人知道可以完成与该代码相同的事情的方法，但是是否可以在使用.net的Windows和使用mono的Linux中运行?

I'm using code that I found on the CodeProject.com for a low-level keyboard hook. The only problem is it uses external DLL calls that don't work in mono. I was wondering if anyone knew of a way to accomplish the same thing as that code, but will run in both Windows using .net, and Linux using mono?

阐明我要执行的操作: 我正在制作类似应用程序的仪表板.该程序位于系统托盘中，当用户按下热键时，它将弹出所有小工具.因此该程序没有焦点，因此通常不会捕获任何击键，因此我使用了低级键盘挂钩，并且挂钩了用户定义为热键的两个按键.但是我为此使用了Windows DLL调用，在使用mono的Linux中这是行不通的.所以我想知道是否有一种方法可以做同样的事情，但是会在Linux上使用mono运行吗?

Clarifying what I'm trying to do: I'm making a Dashboard like application. The program sits in the system tray and when the user presses the hot-key, it will pop up all the gadgets. So the program doesn't have focus, so typically it won't catch any keystrokes, so I'm using the low-level keyboard hook and I hook the two keys that the user defines as the hot-keys. But I'm using a Windows DLL call for that, which doesn't work in Linux using mono. So I'm wondering if there's a way to do the same thing, but will run in Linux using mono?

推荐答案

仅使用.Net不可能获得此行为.您必须为在(Windows，Linux，Mac OS)上运行的每个平台使用二进制驱动程序.可能仅可以使用P/Invoke(检测正在运行的操作系统，调用适当的系统库)，这样就不必分发任何额外"的dll/so/dylib.

It's not possible to get this behavior using only .Net. You have to use a binary driver for each platform you run on (Windows, Linux, Mac OS). It might be possible to use only P/Invoke (detect what OS you are running on, call appropriate system libraries) so that you won't have to distribute any "extra" dll/so/dylib.
