Stuck again on methods

Prime b

Create a method named Sum() that accepts any number of
integer parameters and displays their sum. Write a Main()
method that demonstrates the Sum() method works correctly
when passed one, three, or fi ve integers, or an array of ten
integers.

Um, this is what I have done................Nothing really

        static void Main(string[] args)
        {

        }
        static void Sum(out int[] numbers)
        {

            Console.WriteLine("Please enter as many numbers as you want to see the sum of those numbers: ");
            numbers = Convert.ToInt32(Console.ReadLine());

            for (int index = 0; index < numbers.Length; ++index)
            {

            }
        }

Just time to help with this one, which is a question about parameter arrays, before I turn in:

using System;

class Program
{
static void Main(string[] args)
{
Console.WriteLine("Please enter a single integer :");
string input = Console.ReadLine();
int i = Convert.ToInt32(input);
Console.WriteLine("The sum is {0}", Sum(i));

Console.WriteLine("\nPlease enter 3 integers :");
input = Console.ReadLine();
int j = Convert.ToInt32(input);
input = Console.ReadLine();
int k = Convert.ToInt32(input);
input = Console.ReadLine();
int l = Convert.ToInt32(input);
Console.WriteLine("The sum is {0}", Sum(j, k, l));

Console.WriteLine("\nPlease enter 5 integers :");
input = Console.ReadLine();
int m = Convert.ToInt32(input);
input = Console.ReadLine();
int n = Convert.ToInt32(input);
input = Console.ReadLine();
int o = Convert.ToInt32(input);
input = Console.ReadLine();
int p = Convert.ToInt32(input);
input = Console.ReadLine();
int q = Convert.ToInt32(input);
Console.WriteLine("The sum is {0}", Sum(m, n, o, p, q));

Console.WriteLine("\nPlease enter 10 integers :");
int[] ia = new int[10];
for(int x = 0; x < 10; x++)
{
input = Console.ReadLine();
ia[x] = Convert.ToInt32(input);
}
Console.WriteLine("The sum is {0}", Sum(ia));
Console.ReadKey();
}

static int Sum(params int[] numbers)
{
int sum = 0;

for (int index = 0; index < numbers.Length; ++index)
{
sum += numbers[index];
}

return sum;
}
}
