I am trying to read an excel file.

  this.openFileDialog1.FileName = "*.xls";
            if (this.openFileDialog1.ShowDialog() == DialogResult.OK)
            {
                Microsoft.Office.Interop.Excel.Workbook theWorkbook = ExcelObj.Workbooks.Open(openFileDialog1.FileName, 0, true, 5, "", "", true, Microsoft.Office.Interop.Excel.XlPlatform.xlWindows, "\t", false, false, 0, true);
                Microsoft.Office.Interop.Excel.Sheets sheets = theWorkbook.Worksheets;
                Microsoft.Office.Interop.Excel.Worksheet worksheet = (Microsoft.Office.Interop.Excel.Worksheet)sheets.get_Item(1);
                for (int i = 1; i <= 10; i++)
                {
                    Microsoft.Office.Interop.Excel.Range range = worksheet.get_Range("A" + i.ToString(), "J" + i.ToString());
                    System.Array myvalues = (System.Array)range.Cells.Value;
                    string[] strArray = ConvertToStringArray(myvalues);
                }
            }

On button click i am calling FileOpen Dailog, it is giving error in ExcelObj and ConverToString

The namespaces i am using are:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using Microsoft.Office.Interop.Excel;
using System.IO;
using System.Diagnostics;
using System.Collections;
using Microsoft.Office.Tools;
