Excel.Application app = new Excel.ApplicationClass();
app.Visible = true;
Excel.Workbook workBook = app.Workbooks.Open(templetFile,missing,missing,missing,missing,missing,missing,missing,missing,missing,missing,missing,missing);
Excel.Worksheet workSheet = (Excel.Worksheet)workBook.Sheets.get_Item(1);
for(int i=1;i <sheetCount;i++)

((Excel.Worksheet)workBook.Worksheets.get_Item(i)).Copy(missing,workBook.Worksheets[i]);
