There is lots of good and bad information on the internet about storing passwords. You need to know two things:

1. You should use a 'salted' hash to prevent dictionary attacks
2. You use at minimal the SHA256 hash provider

A quick search gave me this sample code: http://www.obviex.com/samples/hash.aspx

and I'd go with this SaltedHash utility class (looks fairly complete at a glance):
