How do I return the index of an array of sprites as an int?

Question

I am making a Yahtzee game. I have 3 files one has the rolling of the dice function and a list of sprites representing the dice face and a list of buttons representing each individual dice. : using UnityEngine; using UnityEngine.UI;

 public class RollRandom : MonoBehaviour
 {
     //dice for dice roller
     public int dice1;
     public int dice2;
     public int dice3;
     public int dice4;
     public int dice5;
     //faces
     public Sprite[] diceFaces;
     //GameObjects
     public Button[] diceSprites;
 
     void Start()
     {
         dice1 = Random.Range(1, 7);
         dice2 = Random.Range(1, 7);
         dice3 = Random.Range(1, 7);
         dice4 = Random.Range(1, 7);
         dice5 = Random.Range(1, 7);
 
         GameObject SelectionManager = GameObject.Find("SelectionManager");
         SelectDice SelectDice = SelectionManager.GetComponent<SelectDice>();
 
         if (SelectDice.selected1 == false)
         {
             diceSprites[0].image.sprite = diceFaces[dice1 - 1];
         }
         if (SelectDice.selected2 == false)
         {
             diceSprites[1].image.sprite = diceFaces[dice2 - 1];
         }
         if (SelectDice.selected3 == false)
         {
             diceSprites[2].image.sprite = diceFaces[dice3 - 1];
         }
         if (SelectDice.selected4 == false)
         {
             diceSprites[3].image.sprite = diceFaces[dice4 - 1];
         }
         if (SelectDice.selected5 == false)
         {
             diceSprites[4].image.sprite = diceFaces[dice5 - 1];
         }
 
     Debug.Log("Started");
     }
 
     public void GenerateNumber() {
         dice1 = Random.Range(1, 7);
         dice2 = Random.Range(1, 7);
         dice3 = Random.Range(1, 7);
         dice4 = Random.Range(1, 7);
         dice5 = Random.Range(1, 7);
         int z = 0;
 
         GameObject SelectionManager = GameObject.Find("SelectionManager");
         SelectDice SelectDice = SelectionManager.GetComponent<SelectDice>();
 
         if (SelectDice.selected1 == false)
         {
             diceSprites[0].image.sprite = diceFaces[dice1 - 1];
         }
         if (SelectDice.selected2 == false)
         {
             diceSprites[1].image.sprite = diceFaces[dice2 - 1];
         }
         if (SelectDice.selected3 == false)
         {
             diceSprites[2].image.sprite = diceFaces[dice3 - 1];
         }
         if (SelectDice.selected4 == false)
         {
             diceSprites[3].image.sprite = diceFaces[dice4 - 1];
         }
         if (SelectDice.selected5 == false)
         {
             diceSprites[4].image.sprite = diceFaces[dice5 - 1];
         }
 
         int index = System.Array.FindIndex(diceFaces, 0, 5, );
     }
 }

and another file to select dice t hold and not roll with selecting the dice but that one is irrelevant in t$$anonymous$$s case. but the t$$anonymous$$rd one is to manage the playing of the dice in certain places for points. using UnityEngine;

 public class PlayManager : MonoBehaviour
 {
     public int[] faceValue;
     public UnityEngine.UI.Button dice1;
 
     void Start()
     {
         
     }
 
     // Update is called once per frame
     void Update()
     {
         
     }
     public void Manager()
     {
         GameObject RNGManager = GameObject.Find("RNGManager");
         RollRandom rollRandom = RNGManager.GetComponent<RollRandom>();
 
         int index = rollRandom.diceFaces.FindIndex();
     }
 }

what I need to do is return the index of that diceFaces list for each dice so I can add 1 to it and get the value of it. what do I put in the parenthesis after int index = rollRandom.diceFaces.FindIndex();

Here is a video explaining an alternative implementation:

https://www.youtube.com/watch?v=Et_GO_naSKk

And heres the code:

In t$$anonymous$$s implementation to get the values back you can just access the values in your foreach loop or if its not going to cause performance problems to create a new list do somet$$anonymous$$ng like:

var values = Dice.Select(die => die.Roll()) for all new values or var values = Dice.Select(die => die.Value) for all existing.

 using System.Collections.Generic;
 using System.Linq;
 using UnityEngine;
 
 public class GameManager : MonoBehaviour
 { 
     private List<Die> dice { get; set; }
 
     private void Start() 
     {
         dice = FindObjectsOfType<Die>().ToList();
     }
 
     private void Update()
     {
         if(Input.GetKeyDown(KeyCode.Space))
         {
             dice.ForEach(die => die.Roll());
         }
     }
 }

 using UnityEngine;
 
 public class Die : MonoBehaviour
 {
     public Sprite[] Sprites;
 
     public int Value;
 
     private int sides => Sprites.Length;
 
     private SpriteRenderer spriteRenderer { get; set; }
     
 
     private void Start()
     {
         spriteRenderer = GetComponent<SpriteRenderer>();
     }
 
     public int Roll()
     {
         Value = Random.Range(1, sides);
         spriteRenderer.sprite = Sprites[Value - 1];
         return Value;
     }
 }
