C# Console Collision
===

Currently I am making a console game (a rougelike) and I needed some advice on the collision events. I need to tell if there is a wall (▒) next to the player (@) and if so disallow the player from moving in that direction.
Does anyone have any ideas about how I could do this with the console in C#?

If needed I can provide some of my code, although I would rather not do so.
