[Help a noob] [C#] Text Based Game

[Maisteri]

Im planning to make a game in C# for a school project. I picked C# because the code seems to be looking clean and somewhat easy to pick up for a beginner.

Now im wondering which syntaxes(?) i should be looking in to for making a game that works like this:

You have entered the hallway what you want to do?

If given the correct answer here it would progress, if wrong answer it would not progress forward. Also i would like to have more than 1 right answer for some bonus/secret stuff.

PS: Is there a way to use computers in built beeper for some music?

Check this game out: (made by an old friend who's no longer working on it.)
So it will not be completed i guess .

Filebeam - Beam up that File Scottie!

As you can see, it doesent need to look like a damn CMD, you may also add interface & backgrounds as well as music.

Then we have like:

and ofc:

Legend of the Red Dragon - Official Home Page

That's cool and all that but if they dont include any source code they can only give me some inspiration

Still not quite what im looking for. I have no idea really what the parts in his code do and I would like to know this. So a step by step guide for creating a game like this (I've tried google but either im a bad searcher or there is not a guide like this) or just the syntaxes I should look in to. Mainly the ones that print out the messages and determine wheter it's the right or wrong answer.
