Sprite CardList

Hello,
I'm quite new to unity coding side and i'm trying to learn how i would select random 5 images(Cards) from a array and render them on the screen. Can someone give me some help to get started? This is what i have so far. I don't quite understand how i can make random.range use the array.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class DrawCards : MonoBehaviour {
6.  
7.     public Sprite[] CardList;
8.  
9.     // Use this for initialization
10.  
11.      
12.     }
13.  
14.     // Update is called once per frame
15.     void Update () {
16.      
17.     }
18.  
19.     void OnGUI(){
20.  
21. }
22. }
23.
