Thread: I keep getting this error index out of bounds

I was wondering if someone could help me figure out why my code keeps getting this index out of bounds exception. I will post the code and the text file. I just can't figure it out I've tried so many different things to get it to work

Code:

using System;
using System.IO;
using System.Text.RegularExpressions;

namespace Chapter5Problem9
{
    class Program
    {
        const string INPUT_FILE = "\\Projects\\Chapter5Problem9\\Chapter5Problem9\\payRoll.txt";
        const string OUTPUT_FILE = "\\Projects\\Chapter5Problem9\\Chapter5Problem9\\Out.txt";

        static int employees = 7;

        static string[] number        = new string[employees];
        static double[] rate        = new double[employees];
        static double[] hours       = new double[employees];
        static double[] gross       = new double[employees];
        static double[] netPay      = new double[employees];
        static double[] sum         = new double[employees];
        static double[] average     = new double[employees];


        static StreamReader fileIn;
        static StreamWriter fileOut;



        static void Main()

        }

            if (File.Exists(INPUT_FILE))
            {
