Excel automation insert row

Hi,
Can some one help me. I try to insert row between Row 20 and 21 with Excel automation.
Is there some like:
Sheet.Range(21,21).Insert ()

Thanks,
Kristof

Excel.Rows("21:21").Insert

Thank you Alberto
Sheet.range(“21:21”).Insert - also did the job.
I forgot to treat it as a string…

You can use Rows with a number, like this:

Sheet.Rows(21).Insert
