Random Number Generated within Array

Question

Hi guys I want to generate a random number (0-9), for every item I pick up. One random generated number for one item I pick up. I'm having a problem with it being an array, which I know if I set Random.Range(0,10), it will randomly generate one number for all the items, which I don't want. How can I implement the Random.Range to each item with in the array? Here is the code:

  public class RayCasting : MonoBehaviour
     {
         public float pickupDistance;
         public List<Item> items;
     
         
         #region Unity
         void Start ()
         {
             Screen.lockCursor = true;
         }
         void Update ()
         {
             RaycastHit hit;
             Ray ray = new Ray(transform.position, transform.forward);
             if (Physics.Raycast(ray, out hit, pickupDistance))
             {
                 foreach(Item item in items)
                 {
     
                     if(Input.GetMouseButtonDown(0)) {
                         if (item.gameObject.Equals(hit.collider.gameObject))
                     {
                         numItemsCollected++;
                         item.Collect();
                         break;
                             }
                     }
                 }
             }
         }
         
         void OnGUI()
         {
     
             GUILayout.BeginArea(new Rect(130,400,100,100));
             {
                 GUILayout.BeginVertical();
                 {
             if (numItemsCollected < items.Count)
             {
                 foreach (Item item in items)
     
                             GUILayout.Label(string.Format("[{0}] {1}", item.Collected ? "X" : " ", item.name));
             }
             else
             {
                 GUILayout.Label("You Win!");
             }
                 }
                 GUILayout.EndVertical();
         }
             GUILayout.EndArea();
         }
         #endregion
         
         #region Private
         private int numItemsCollected;
         #endregion
     }
     
     [System.Serializable]
     public class Item
     {
         public string name;
         public GameObject gameObject;
         
         public bool Collected { get; private set; }
         
         public void Collect()
         {
             Collected = true;
             gameObject.SetActive(false);
         }
     }

 int[] randomArray = new int[10];
 for(int arrayIndex = 0; arrayIndex < randomArray.Length; arrayIndex++)
 {
    randomArray[arrayIndex] = Random.Range(0, 10);
 }

Do you mean like this? Or does the number get generated inside the single Item class??

 int randomNumber;    
 void Awake()
 {
    randomNumber = Random.Range(0, 10);
 }
