How do I save information into an array in c#?

Question

I am in a very, very basic class. Essentially I wanted to use a function -- one that returns the double data type for each iteration of my for loop. I was able to accomplish this using a method (since arrays are already passed by reference into a method), but I was curious, could I accomplish the same thing using a function?

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

namespace Chapter8_Prob_8

{

    class Program

    {

        const int MAX_SIZE = 7;

        static void Main(string[] args)

        {

            double[] empId = new double[MAX_SIZE] { 56588, 45201, 78951, 87775, 84512, 13028, 75804 };

            //the book calls for an integer array to hold the number of hours worked by each employee

            //this is unrealistic to use an integer, I need more points of accuracy. I will use a double.

            double[] hours = new double[MAX_SIZE];

            double[] payRate = new double[MAX_SIZE];

            double[] wages = new double[MAX_SIZE];

            //function to get the hours of the employees

            getHoursAndPay(empId, hours, payRate);

            calcWages(hours, payRate, wages);

            displayResults(empId, hours, payRate, wages);

        }//end main


Instead of using calcWages(hours, payRate, wages);
 would it be possible to have something like,
wages = calcWages(hours, payRate) and then have a function that would return
each 'wage' into each element of the array?
