var options = new[] { "a", "b" };
var selections = Array.Empty<string>();

var userInput = Console.ReadLine();

if (options.Contains(userInput))
  selections = selections.Concat(userInput);

var options = new[] { "a", "b" };
var selections = Array.Empty<string>();

var userInput = Console.ReadLine();

if (options.Contains(userInput))
  selections = selections.Concat(userInput);

here we have an array of items, and if the input matches one of those items, it gets added to the second array what are you trying to do?

I'm doing like a backend with simple c# for college so i have 4 arrays ( 3 string & 3 double) 2 from the string are for products and 2 from the doubles for prices When the user want to add item to the cart they will copied to cart string array and the price will copied to double total price for cart @blinkbat

at that point i would make a simple class

public class Product
{
  public double Price { get; set; }
  public string Name { get; set; }
}

public class Product
{
  public double Price { get; set; }
  public string Name { get; set; }
}

and just pass around instances of Product
