There's a fairly comprehensive article on this over at Code Project: http://www.codeproject.com/KB/system/KeyLogger.aspx

While that article is based around C++ etc it covers a lot of the technical details you need to know.

There is an example C# project here: http://www.codeproject.com/KB/system/simple_key_log.aspx.

You need a global keyboard hook, which will allow your application to listen in on keyboard input events system-wide. You implement this by P/Invoking the SetWindowsHookEx function and specifying the WH_KEYBOARD_LL flag for the idHook parameter. The entire process can get slightly complicated.

But it turns out that you're in luck. Stephen Toub has already written the code for you here on his blog: Low-Level Keyboard Hook in C#. Just drop this into your project and you're in the spy business.
