int count = 0; ArrayList raffleList = new ArrayList(); int[] raffleNumber = new int[5]; foreach (int number in raffleNumber) { Console.WriteLine("Please write a number from 1-60 that you would like to choose."); raffleNumber[count] = Convert.ToInt32(Console.ReadLine()); } raffleList.Add(raffleNumber); Array.Sort(raffleNumber); Console.WriteLine(raffleNumber); Console.ReadLine(); Help would be appreciated

You can't just pass an array to console writeline Use string.Join to turn it into a string Also, use a for loop, not a foreach

And god do not use ArrayList

Maybe something like this?

int MAX_AMOUNT_OF_RAFFLE_NUMBERS = 5;
int MIN_NUMBER = 1;
int MAX_NUMBER = 60;
List<int> raffleList = new();


for (int i = 0; i < MAX_AMOUNT_OF_RAFFLE_NUMBERS; i++)
{
    Console.WriteLine($"Please write a number from {MIN_NUMBER}-{MAX_NUMBER} that you would like to choose.");
    var userInput = Console.ReadLine();

    _ = int.TryParse(userInput, out int number);
    if (number <= MAX_NUMBER && number >= MIN_NUMBER)
    {
        raffleList.Add(number);
    }
    else
    {
        Console.WriteLine("Incorrect value entered");
    }
}

raffleList.Sort();

Console.WriteLine(String.Join(",", raffleList));

int MAX_AMOUNT_OF_RAFFLE_NUMBERS = 5;
int MIN_NUMBER = 1;
int MAX_NUMBER = 60;
List<int> raffleList = new();


for (int i = 0; i < MAX_AMOUNT_OF_RAFFLE_NUMBERS; i++)
{
    Console.WriteLine($"Please write a number from {MIN_NUMBER}-{MAX_NUMBER} that you would like to choose.");
    var userInput = Console.ReadLine();

    _ = int.TryParse(userInput, out int number);
    if (number <= MAX_NUMBER && number >= MIN_NUMBER)
    {
        raffleList.Add(number);
    }
    else
    {
        Console.WriteLine("Incorrect value entered");
    }
}

raffleList.Sort();

Console.WriteLine(String.Join(",", raffleList));

Its part of my course as like practice so i need to use it somewhere, but if it cant be used here then thats okay

Thinker•9mo ago

If it's part of your ancient course then sure it's fine, but you should never ever use it in any other circumstances.

Yeah its an Alevel course soooo i need to at least learn how it works, but from ur ominous message i get that i shouldnt use it 😭

Its a 20 year old class with literally not a single usecase left It still exists only for backward compatibility, and should never be used

Yeah sorry I should like actually explain it. ArrayList was added all the way back in C# 1, back when the language didn't have this nifty thing called generics, but then in C# 2 generics were added along with the List<T> class, which is better in literally every single way. So tl;dr: ArrayList is really old and has no purpose for existing. sniped again Smadge
