How to: Copy a Row or Column
This example demonstrates how to copy a row or column in a worksheet.
To do this, access a destination row (Row) or column (Column) object and call its CellRange.CopyFrom method. Pass the source row or column object as a parameter. If you need to specify the type of data be copied (for example, values only, formats only, formulas only, borders only, etc.), pass the required member of the PasteSpecial enumerator as well.
// Copy all data from the 2nd row to the 5th row. worksheet.Rows["5"].CopyFrom(worksheet.Rows["2"]); // Copy only borders from the "B" column to the "E" column. worksheet.Columns["E"].CopyFrom(worksheet.Columns["B"], PasteSpecial.Borders);
