How to use Array.IndexOf() for sprites?

Questions & Answers
1

I have an array with about 25 sprites. I also have a string that will hold a sprite name, how would I be able the Array.IndexOf() to find the index of a sprite. Here is my crude implementation, but I keep getting an error:

//Decleration of Background Images
	[Header("Background Images")]
	public Sprite[] spriteBackgroundList;

	[Header("Sprite Renderer")]
	[SerializeField]
	private SpriteRenderer backgroundRenderer;
	
	[Header("Variables")]
	public string currentBackground;

	//Start is called before the first frame update
	private void Start()
	{
		currentBackground = "Black Background";
	}

	//Update is called once per frame
	private void Update()
	{
		if(currentBackground!.Contains(backgroundRenderer.sprite.name))
		{
			backgroundRenderer.sprite = spriteBackgroundList[Array.IndexOf(spriteBackgroundList,  s => s.name == currentBackground)];
		}
	}

SOLVED:

I used Array.FindIndex() The updated code looks like this

indexToFind = Array.FindIndex(spriteBackgroundList, s => s.name == currentBackground);

			backgroundRenderer.sprite = spriteBackgroundList[indexToFind];
