Can't add multiple integers to a List in a Loop!

Hey,
I’ve had this problem for a long time now. I think I know what the problem is, but I don’t know how to solve it.
Here is my problem:
I want that every time I call the Run() function, a random number ( i ) that has not been used before is debugged.

public List List01 = new List();

void Run()
{
    while (List01.Contains(i))
    {
        i = Random.Range(1, 10);
    }
    List01.Add(i);
    //make something with i like debugging
    Debug.Log(i);
}

my research says that the reference of i does not change and so the index is always overwritten.
Can anyone help me?

thanks!

This is very confused.

are you just trying to generate a list of random order ints between a range of values?

If so why not just create a list of integer values and then randomise the order of the list instead?

using System.Collections;
using System.Collections.Generic;
using System.Linq;
using UnityEngine;

public class Test : MonoBehaviour
{
    public static void Shuffle<T>(IList<T> ts)
    {
        var count = ts.Count;
        var last = count - 1;
        for (var i = 0; i < last; ++i)
        {
            var r = UnityEngine.Random.Range(i, count);
            var tmp = ts*;*

ts = ts[r];
ts[r] = tmp;
}
}

public Stack NumberStack;

void Start()
{
var randomNumbers = Enumerable.Range(0, 10)
.ToList();
randomNumbers.Shuffle();
NumberStack = new Stack(randomNumbers);

Debug.Log(NumberStack.Pop());
Debug.Log(NumberStack.Pop());
Debug.Log(NumberStack.Pop());
Debug.Log(NumberStack.Pop());
Debug.Log(NumberStack.Pop());
Debug.Log(NumberStack.Pop());
}
}

Try this.

    public List<int> List01 = new List<int>();

    // Update is called once per frame
    void Start()
    {
        List01.Add(5);
        getNewNumeber(5);
    }

    int getNewNumeber(int i)
    {
        int n = 0;
        int result;

        if (!List01.Contains(i))       // Check if there is an i already
        {
            result = i;                // No. Ok to use.
            List01.Add(i);
        }
        else
        {
            do
            {
                n = Random.Range(1, 10);       // returns 1:9
            } while (List01.Contains(n));      // keep trying to find a number not in the list.
            List01.Add(n);
            result = n;                        // New number
        }
        //make something with i like debugging
        Debug.Log(n);

        return result;
    }
