Dictionary of gameObjects with Integers as keys

I have the following public fields referencing GameObjects in my script

Code (csharp):

1.  
2.  public GameObject tile0;
3.     public GameObject tile1;
4.     public GameObject tile2;
5.     public GameObject tile3;
6.     public GameObject tile4;
7.     public GameObject tile5;
8.     public GameObject tile6;
9.     public GameObject tile7;
10.     public GameObject tile8;
11.  

I need to be able to reference these gameObjects by integer values.
So an int value of 0 would point to tile0, etc.

Can anyone help with setting up the dictionary properly?

 

Just need a list for this mate, since you can use the index to reference the gameobjects.

Code (CSharp):

1.  
2. //This is required to use lists
3. using System.Collections.Generic;
4.  
5. //This is how you initialize the list
6. public List <GameObject> tiles = new List<GameObject> ();
7.  
8. //Let's say you want to do something with tile 4. You can access the list like this.
9. tiles [4].SetActive (false);
