How to verify inputted username and password against a database? C#

Question

I'm doing my coursework using windows forms (not going to be actually used so storing passwords isn't an issue I'm worried about it) and I can't figure out how to check what a user has said their username+password is against my database which stores all the usernames+passwords to see if they're actually a user or not.

How do I go about doing this?

What I have tried:

I've tried googling solutions but nothing I can find applies to me (not using asp.net etc) or is too complex for me to understand and implement.

"not going to be actually used"

Famous last words! Even the simplest demo will end up being copied and used in a production application.

Better to do it properly from the start:
