My Random Number generator isn't displaying numbers

I would like some help. I'm still kind of new to coding, but it seems like the numbers for my Random Number Generator isn't displaying the numbers.

The way I would like the numbers to be displayed is one after the other? Like you press a button and it shows a new number in its place.

Here's my code:

using System.Collections.Generic;
using System.LINQ;
using System.Text;
using System.Threading.Tasks;

Namespace ConBingo
{
    class Program
    {
        static Random RanGen = new Random();

        static void Main(string[] args)
        {

            int[] Nums = new int[90];

            while (true)
            {
                Randomise(Nums);
            }
            
        }
            

        static void Randomise(int[] Nums)
        {
            int RanNum, Temp;

            //Set first entry to 1, second to two etc.
            for (int counter = 0; counter<Nums.Length; counter++)
                Nums[counter] = counter + 1;

            // now swap each number with another chosen at random
            for(int Pass = 0; Pass<Nums.Length;Pass++)
            {
                // choose a random number
                RanNum = RanGen.Next(Nums.Length);

                // first pass swap first number with one chosen at random, second pass sway second number
                Temp = Nums[Pass];
                Nums[Pass] = Nums[RanNum];
                Nums[RanNum] = Temp;
            }
        }

    }
}
