make an array which you will fill with the numbers you want to randomize

make a randomNumberGenerator from zero to ↑array.Count and then just give out the array[randomGeneratedNumber]

C#

int[] asdf = {2,3,5,8};

var r = new Random();
// print random integer >= 0 and  < 4
Console.WriteLine(r.Next(4));

// print random integer >= 0 and < 4
Console.WriteLine(r.Next(0, 4);)

Console.WriteLine(asdf[r.Next(0,3)]);

Hi,
Put your number in a table.
Do random between 0 and size of table ( cast to integer).
Then select the member of table like Table[random].
you can also use a dictionnary or other feature of langage.
Best regards.
