Does microwaving destroy vitamins?

Microwave ovens generally do not destroy nutrients in food. For example, cooking vegetables in water increases the loss of water-soluble vitamins, and because microwave ovens can cook foods with little or no water, more nutrients are retained.

Does heat destroy vitamin C?
