How do I get the first row in an excel workbook & save it to a new excel workbook using .net c#? I dont know the amount of columns so need to get entire row. This what I have but the new workbook is blank (no row copied) Excel.Workbook xlWorkbook = xlApp.Workbooks.Open(file); Excel._Worksheet xlWorksheet = xlWorkbook.Sheets[1]; Excel.Range xlRangeHeader = xlWorksheet.get_Range("A1", "A1").EntireRow; Excel.Workbook xlWorkbookNew = xlApp.Workbooks.Add(); Excel._Worksheet xlWorksheetNew = xlWorkbookNew.Sheets[1]; xlWorksheetNew.get_Range("A1", "A1").EntireRow.Value = xlRangeHeader; xlWorkbook.Close(false); xlWorkbookNew.SaveAs(Path.Combine(sDestination, Path.GetFileName(file)), fileFormat); xlWorkbookNew.Close(true);
