c# - Why do I get an error in the loop in this code?

Question

I can do this with "for" loop, but why does it say it's outside of bounds of the array when I try with "for each"? The text file numbers are 9 2 1 3 4 4.

 string text = File.ReadAllText("txt.txt");         
            string[] bits = text.Split(' ');
            int[] numere = Array.ConvertAll(bits, int.Parse);
            

            
            foreach (int item in numere)
            {

                Console.WriteLine(numere[item]);
                
            }

Answer 1

You are using the foreach function wrong. In foreach loop you are iterate the items value of the collection each iteration, so the item variable in your case is the value of the cell in that iteration and not his index (like in regular for loop).

It will look like this:

foreach (int item in numere)
{
    Console.WriteLine(item);
}
