如何用c#新建一个含有一个sheet的Excel文件

[vvflower]

add的4个参数是什么意思？有代码吗？

[shuker]

Excel.ApplicationClass app = null;

try
{
app = new ApplicationClass();
}
catch(Exception e1)
{
return false;
}

object oMissing = System.Reflection.Missing.Value;
try
{
try
{
app.Workbooks.Add(oMissing);
}
catch(Exception e)

return false;
}
Excel.Worksheet ws = (Excel.Worksheet)app.ActiveWorkbook.ActiveSheet;
//do something on ws

#if OFFICE2000
app.ActiveWorkbook.SaveAs(strFileName, oMissing, oMissing, oMissing, oMissing, oMissing, Excel.XlSaveAsAccessMode.xlNoChange, oMissing, false, oMissing, oMissing);
#else
app.ActiveWorkbook.SaveAs(strFileName, oMissing, oMissing, oMissing, oMissing, oMissing, Excel.XlSaveAsAccessMode.xlNoChange, oMissing, false, oMissing, oMissing, oMissing);
#endif
app.ActiveWorkbook.Close(false, oMissing, oMissing);
}
catch(Exception ex)
{
return false;
}
finally
{
try
{
app.ActiveWorkbook.Close(false, oMissing, oMissing);
}
catch {}
try
{
app.Quit();
}
catch {}
}
return true;
