Question

The DataTable has a method called ImportRow(), There is also a method unders the rows called Add(). So what’s the difference between these methods?

dataTable.Rows.Add(newRow);

vs

dataTable.ImportRow(newRow);

Answer 1

• ImportRow preserves any setting of the row: DataRowState,values etc.
• Add calls NewRow that initialize a row using default values.

ImportRow is useful if you’re importing a row from another table and you need to preserve all because you’re planning to use a DataAdapter
