Your question is not clear.

Do you want to set the number format to "hh:mm:ss"? If so you can do:

worksheet.Cells["A1"].NumberFormat = "hh:mm:ss";

Do you want to get the formatted value of the cell as a string?

string formattedValue = worksheet.Cells["A1"].Text;

If it is something else, please try to make your question clearer.
