Add a sheet to excel

Question

Hi,

I wrote code like this for excel.

 Microsoft.Office.Interop.Excel.Application xla = new Microsoft.Office.Interop.Excel.Application();

               Workbook vb = xla.Workbooks.Add(XlSheetType.xlWorksheet);

               Worksheet ws = (Worksheet)xla.ActiveSheet;

               xla.Visible = true;



How can i add a new sheet to workbook??
