Row

This example demonstrates how to insert new rows into a worksheet.

• Use the Row.Insert method to add a new row above the current row.
• Call the RowCollection.Insert method of the Worksheet.Rows collection to insert a row at the specified position or add multiple rows at once.
• To insert empty rows above the specified cell range, use the Worksheet.InsertCells method with the InsertCellsMode.EntireRow enumeration member passed as a parameter. This method inserts the same number of rows as the specified cell range contains.

Enclose your code in the Workbook.BeginUpdate - Workbook.EndUpdate method calls to improve performance when you add multiple rows to a document.
