You must choose a method to create a new DataRow to add to a DataTable. The DataRow should reference DataColumns defined by the DataTable before it is added to the DataTable.

What method should you choose?

To add a new row, first call the DataTable.NewRow method. This method ensures that DataRow references defined DataTable DataColumns.

The RowCollection.Add method does not create a new DataRow unless you use an overload that creates a DataRow and adds it to the RowCollection. This overload does not allow you to access the defined DataColumns before adding to the DataTable.
