C# console App

im creating a text base adventure game and need help with creating an array.

the game is set up to take thr users through a series of locations via methods.

my issue is i need to set up an array item collection and item usage.

i.e.

if there 5 locations, each location is its own method, ill need the array to be able to access the array within 3 of those methods for the user to collect 3 different items. so like if location 1 contains a sword, location 2 has a potion and location 4 has a rope.

im not sure if any of this makes sense, but im new to this. :)
