DataTable::GetChanges Method ()
Assembly: System.Data (in System.Data.dll)
Creates a new DataSet containing a copy of all rows in the original DataSet that have pending changes. Relationship constraints can cause additional unchanged rows to be added to the new DataSet if the unchanged rows contain primary keys corresponding to foreign keys in the changed rows. The method returns null (Nothing in Visual Basic) if there are no rows in the original DataSet with pending changes.
