How to rename excel sheet name dynamically in C#

Question

I have created an excel workbook with many sheets like sheet1, sheet2,... etc. How can I rename these tab names dynamically in C#?

Answer 1

You didn't spedify how do you access the excel file. However, example from here might be useful for you if you're using Microsoft.Office.Interop.Excel. Note that it opens first sheet in the file, line: (Worksheet)xlBook.Worksheets.get_Item(1)

using Excel = Microsoft.Office.Interop.Excel; 

    object oMissing = System.Reflection.Missing.Value;
    Excel.ApplicationClass xl=new Excel.ApplicationClass();
        Excel.Workbook xlBook;
        Excel.Worksheet xlSheet;
        string laPath = Server.MapPath(@"\excel\xl_table.xls");
        xlBook = (Workbook)xl.Workbooks.Open(laPath,oMissing,
          oMissing,oMissing,oMissing ,oMissing,oMissing,oMissing
         ,oMissing,oMissing,oMissing,oMissing,oMissi ng,oMissing,oMissing);
        xlSheet = (Worksheet)xlBook.Worksheets.get_Item(1);
        xlSheet.Name = "CIAO";
        xlBook.Save();
        xl.Application.Workbooks.Close();

One short note: If you don't need to specify them, you can get rid of all these optional parameters and use the short form:

xlBook = (Workbook)xl.Workbooks.Open(laPath);
