Detect if any key is pressed in C# (not A, B, but any)

Question

[EDIT 3] I kind of "solved it" by at using the "strange" version. At least for the most important keys. It is suffient for my case, where I want to check

Answer 1

In the Key Enumeration there is an Enumeration value of Zero(0), which basically tests "No Key Pressed", which is opposite of "Any key pressed". So, something like this might work;

If !GetKeyState(0)==True then
    Do Something
End If

Or

If GetKeyState(0)==False then
    Do Something
End If
