Just like carbon, it can have +4 or -4, as it can either lose 4 electrons (+4) or gain 4 electrons (-4) (They are both in group 4, C is period 2, Si is period 3).
If you have Carbon tetrachloride (a.k.a. Tetrachloromethane), the Carbon would be +4, as Chlorine is more electronegative, so it would be -1 each.
If you have Methane, however, the Carbon would be -4, as Hydrogen pretty much always has an oxidation state of +1.

I just feel I should point out there is a big, big difference between oxidation state and the charge of the ion. You will never, I repeat, never, come across a silicon 4+ or 4- ion, the same goes for carbon.
They are fundamentally different things - don't write the wrong thing in an exam!

I presumed OP meant oxidation state
Anyway, what about carbides, like tungsten carbide?
