Returning a random value via char array

I'm trying to create an a blackjack game for my C# class and I've been trying to figure out how to obtain a random suit/card value from reciprocating char arrays. The goal is to return these values to a console application to "test" the return values and see if they're correct/adequate.

I have already declared the fields, properties, and set up a constructor. I just can't figure out how to get the values to return them so that they can be tested. We've just started using these things in my class as well.
