Cash payments are getting less common all the time in Norway. I can't think of a single thing you might need cash for. Also taxis and public transport can be paid by card.
You should however verify your bank's fees. It is not uncommon for many banks to charge relatively high fees, either as a flat amount, a percentage or hidden as a currency exchange fee, for card usage abroad.

Most of the cards are accepted around Europe. It will make an own calculation of the courses for the Norwegian Crowns to Euros when you make a transaction.
Do you have a credit card? Hotels might ask for a credit card. If you have, I would take it with you. If you already paid the hotel, there's no need!
However, I should take some Crowns with you, just to be sure if you need a cab or something. It can't hurt!
EDIT: as the comments states below, take the money out of the wall when you arrive! That is much cheaper than to pick it up at Schiphol.
