我看到了一些软件，记录被输入，它是安装在计算机上的所有按键的一天。我将如何去写这样的使用.NET Windows服务？

I saw some software the other day that logs all keystrokes that are typed on the machine that it is installed on. How would I go about writing something like this using a .NET Windows service?

推荐答案

只需使用的 调用SetWindowsHookEx（）

Just use the SetWindowsHookEx()

请注意：您不需要为这个管理员权限，我还没有找到一个单一的病毒扫描软件或恶意软件的工具抱怨code使用这种。 AFAIK，竟然没有一个API来枚举所有已安装的挂钩，所以任何人都可以安装在Windows系统上一个键盘记录器，也没有办法发现。

Note: You don't need admin rights for this and I haven't found a single virus scanner or malware tool complain about code which uses this. AFAIK, there isn't even an API to enumerate all installed hooks, so anyone can install a keyboard logger on Windows systems and there is no way to notice.
