.NET Framework class library
DataTable.newrow method
Create a new DataRow with the table with the same architecture.
[Visual Basic]
Public function new () AS DATAROW
[C #]
Public DataRow newRow ();
[C ]
PUBLIC: DATAROW * new ();
[Jscript]
PUBLIC FUNCTION NEWROW (): DATAROW;
return value
DataRow, its architecture is the same as the DataTable architecture.
Note
The new DataRow object with the DataTable with the new DataBole must be created using the new path method. After creating DATAROW, you can add it to the DataRowCollection via the DataTable object's ROWS attribute.
Example
[Visual Basic, C #, C ] The following example creates a DataTable, add two DataColumn objects for determining the schema of the table, and create a few new DataRow objects using the Newrow method. Then add these DATAROW objects to the DataRowCollection using the Add method.
