Get all materials with tag, best way?

Alright, the following code should work, but it just seem alot of code for something quite simple, is there any simpler way of doing this?

Code (csharp):

1. public Material[] dots;
2.  
3.     void Awake()
4.     {
5.         dots = new Material[4];
6.        
7.         Renderer[] rendererdots = GameObject.FindWithTag("dots").GetComponentsInChildren<Renderer>();
8.  
9.         int i = 0;
10.         foreach(Renderer rndr in rendererdots )
11.         {
12.             dots[i] = rndr.material;
13.             i++;
14.         }
15.      }
