DeviceIOControl is simply a way of passing "op-codes" to a kernel mode device driver and retrieving the results. You obviously can't *write* a device driver in C# but you can interrogate a device driver via pinvoke.

 (just to make it clear to me, not to nittpick ;))
 But isn't this just a wrapper around Windows' device manager? There is no
 way you will be able to poke into hardware without a kernel space module, as
 everything is virtualized: you can't simply throw an interrupt or set an
 address to a value to change some hardware's internal settings (at least
 that's what I know of it).
