If it's the 4th, shouldn't the index be 3 since you are using C#? C# indeces are zero-based.

xlWorkSheet= (Microsoft.Office.Interop.Excel.Worksheet)xlWorkBook.Worksheets.get_Item(0);
xlWorkSheet1 = (Microsoft.Office.Interop.Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);
xlWorkSheet2 = (Microsoft.Office.Interop.Excel.Worksheet)xlWorkBook.Worksheets.get_Item(2);
xlWorkSheet3 = (Microsoft.Office.Interop.Excel.Worksheet)xlWorkBook.Worksheets.get_Item(3);

By default MS Excel stores 3 worksheets. If you want to save data into 4. worksheet, you need to add it.
