I want to add a empty row in worksheet.
Thanks for using Aspose APIs.
Please use Worksheet.Cells.InsertRows() method for your needs. Please see the following sample code, its comments, input and output Excel files and screenshot for a reference.
The code inserts 10 empty rows starting from 3rd row.

Worksheet sheet = workbook.Worksheets[0];
