Importing Excel data to multi dimensional array in C#

I am trying to import data from an excel sheet from certain cells for example Column A and B into a multidimensional array.

        Excel.Application xlApp = new Excel.Application();
        Excel.Workbook xlWorkbook = xlApp.Workbooks.Open(@"C:\\Users\\a_hebiba\\Desktop\\Lol1.xlsx");
        Excel._Worksheet xlWorksheet = xlWorkbook.Sheets[1];
        Array Cranelocations;
        Excel.Range xlRange = xlWorksheet.get_Range("A", "B".ToString());



        Cranelocations = (Array)xlRange.Cells.Value;
        Console.WriteLine(Cranelocations);
        Console.ReadLine();

then i am trying to take these data from the array to apply a certain equation on it but i don’t know how to read the data from the array anymore.

for (int m = 0; m < Weights.Length; m++)
        {
            int offset = m * Cranelocations.GetLength(0);

            for (int i = 0; i < Cranelocations.GetLength(0); i++)
            {
                for (int j = 0; j < Picklocation.GetLength(0); j++)
                {
                    double x = Cranelocations[i,0]- Picklocation[j, 0];
                    double y = Cranelocations[i, 1] - Picklocation[j, 1];

                    result1[i + offset, j] = Weights[m] * (Math.Sqrt(Math.Pow(x, 2) + Math.Pow(y, 2)));
                }
            }
        }
