EXCEL怎么导出工作薄模板中单个工作表

EXCEL如何导出工作薄模板中单个工作表
请高手指点如何用C#代码将工作薄模板中的单个工作表导出到文件中

比如现在我工作薄模板有20个工作表，如何将其中一个工作表导入数据修改后另存为一个单独的文件。

C# code

        private void copy_excel_sheet(string sFileName, string sSaveName)        {            Excel.Application xlApp1 = new Excel.ApplicationClass();            object missing = Type.Missing;            Excel.Workbook xlSrcBook;            Excel.Workbook xlDestBook;            //xlApp1.Visible = true;            xlApp1.Workbooks.Open(sFileName,                missing, missing, missing, missing, missing, missing, missing,                missing, missing, missing, missing, missing, missing, missing);            xlSrcBook = xlApp1.ActiveWorkbook as Excel.Workbook;            xlDestBook = xlApp1.Workbooks.Add(missing);            xlApp1.DisplayAlerts = false;            xlDestBook.SaveAs(sSaveName,                missing, missing, missing, missing, missing, Excel.XlSaveAsAccessMode.xlNoChange,                 missing, missing, missing, missing, missing);            xlApp1.DisplayAlerts = true;            try            {                Excel.Worksheet xlsheet;                xlsheet = (Excel.Worksheet)xlSrcBook.Sheets[2];                xlsheet.Copy(missing, xlDestBook.Sheets[xlDestBook.Sheets.Count]);            }            catch (Exception ex)            {                MessageBox.Show(this, ex.Message);            }            finally            {                xlSrcBook.Close(missing, missing, missing);                xlDestBook.Save();                xlDestBook.Close(missing, missing, missing);                xlApp1.Quit();                xlApp1 = null;            }            MessageBox.Show("Done!");        }
