Trying to write a text-based game in order to learn C#

I am trying to learn C#, and im much better at learning by doing than by reading/watching video. I'd also love to have some evidence of my improvement. Thats why i want to try to write a text-based command console game. I still know very little about this, thats where this post would come in. I want to make it so that the options have a number assigned to them, like for example '1. this option does this' '2. This option does that' and so on. But now that i started on it i realize i know very little about this subject. The goal is to have the player choose what they do/say with the number keys. But i dont know how to go about that. Is there anyone that can inform me on how i can go about that (using example code?). thanks already.
