Insert text in specific cell in Excel c#

Question

I need to insert text in 5th row ist column and another text in 5th row 2nd column... How do I do this? Below is the code am using and get out of range exception:

Excel.Application xlApp;
Excel.Workbook xlWorkBook;
Excel.Worksheet xlWorkSheet;
Excel.Worksheet xlWorkSheet2;
Excel.Worksheet xlWorkSheet3;
Excel.Range oRange;

xlApp = new Excel.Application();

xlWorkBook = xlApp.Workbooks.Add(misValue);

xlWorkSheet2 = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);
xlWorkSheet2.Name = "The chart sheet";

xlWorkSheet2.Cells[5, 1] = "First Name";
xlWorkSheet2.Cells[5,2] = "Last Name";  

Answer 1

Before the cell insertion above you have to add a worksheet

Excel.Application excelApplication = new Excel.Application();
Excel.Workbook excelWorkBook = excelApplication.Workbooks.Add();
Excel.Worksheet wkSheetData = excelWorkBook.ActiveSheet;
excelApplication.Cells[5, 2] = "TextField";

I hope this helps
