Note: it is slightly faster to use the WorksheetRow.GetCellComment method and check for a non null return value, which does not create a WorksheetCell instance internally. However, if a reference to the WorksheetCell instance already exists, using this property is equivalent to using the WorksheetRow.GetCellComment method and checking for a non null return value.
