Assembly: System.Data (in system.data.dll)
All rows in all tables are removed. An exception is generated if the table has any enforced child relations that would cause child rows to be orphaned.
If the DataSet is bound to an XmlDataDocument, calling DataSet.Clear or DataTable.Clear raises the NotSupportedException. To avoid this situation, traverse each table, removing each row one at a time.
