Created an array in a file called tablearray.cs. I want to use it on another page. getting Table.Rate is inaccessible due to protection level.

First i have an array below is a part of it.

namespace testarray
{
    public  partial class Table
    {
        double[,] Rate = new double[,]
        {
            { 0.25,    0.384615385, 0.153846154 },
            { 0.255,   0.395348837, 0.15503876 },
            { 0.26,    0.40625,     0.15625 },
            { 0.265,   0.417322835, 0.157480315 },
            { 0.27,    0.428571429, 0.158730159 },

I placed the following code in the same file

public Tuple<double, double, double> GetRates(double input)
{

    double PercentToGive = 0;
    double ValueStore = 0;
    double ValueAdmin = 0;

    foreach (int x in Rate)
    {
        if (Rate[x, 0] == input)
        {
            PercentToGive = Rate[x, 0];
            ValueStore = Rate[x, 1];
            ValueAdmin = Rate[x, 2];
            break;


        }
    }

and than in the page to call this

Tuple<double, double, double> resultTuple = Table.GetRates(Convert.ToDouble(txtInput.Text));

I get this error

CS0120 An object reference is required for the non-static field, method, or property ‘Table.GetRates(double)’

Then i copied the Getrates to the same page that i call the function on.

` public Tuple<double, double, double> GetRates(double input)
{

 double PercentToGive = 0;
 double ValueStore = 0;
 double ValueAdmin = 0;

 foreach (int x in Table.Rate)
 {
     if (Rate[x, 0] == input)
     {
         PercentToGive = Rate[x, 0];
         ValueStore = Rate[x, 1];
         ValueAdmin = Rate[x, 2];
         break;


     }`

Table.Rate is inaccessable due to its protection level.

I have looked online and can’t find the answer
