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

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);
