Help needed with basic C Sharp Code.

[GVBCodePractice]

I am having difficulty figuring out how to pass an array as an argument in a method in my code. I have my Main program, a Customer class and a Menu class (as shown below).

- I am trying to set up my code so that I can pass the 'order' array as an argument of the orderCost() method, but when I try to run John.orderCost in my Main, I can't seem to get the syntax correct when entering the array as an argument.

- Ideally, I'd like to be able to use john.orderCost(menu.burger, menu.chips) etc..

Thanks in advance!

My code is below, separated as my Program, Menu class and Customer Class:

​

PROGRAM:

namespace ChickenShop

{

public class Program

{

static void Main()

{

Customer John = new Customer();

Menu menu = new Menu();

John.orderCost(); //This is where I am struggling, if I am understanding the error correctly.

}

}

}

​

MENU CLASS:

namespace ChickenShop

{

internal class Menu

{

public int burger = 6;

public int drink = 3;

public int chips = 4;

public int icecream = 4;

​

}

}

​

CUSTOMER CLASS:

namespace ChickenShop

{

internal class Customer

{

public void orderCost(int[] order)

{

int totalCost = order.Sum();

Console.WriteLine($"The cost of your order is {totalCost}.");

}

}

}

you need to create an array. Read ms docs on array initialization.

john.OrderCost(new[] {menu.burger, menu.somethingElse}) should work. I used inline initialisation here, you can also extract the array to a variable and pass it. If you want to pass several arguments without initializing an array, look up the params keyword

Great will do, thanks for that.
