How can I capture a key press, outside of the form?

问题

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

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

I suspect that I will have to do the

[DllImportAttribute("user32.dll")]

, but I have little to no experience with that.

回答1:

Being able to capture key presses anywhere requires using Hooks.

There is a library on CodePlex which simplifies implementing Application and Global Mouse and Keyboard Hooks for C# users.
