ADO.NET in a Nutshell

This enumeration is used to specify the IDataAdapter.MissingMappingAction property, which determines what happens when a DataSet is filled using columns or tables that don't have corresponding System.Data.Common.DataColumnMapping or System.Data.Common.DataTableMapping . The default value, Passthrough , simply means that the original name will be used. You can also use Ignore , in which case the column or table aren't added, or Error , in which case a System.SystemException is thrown. Mapping information must be added to a data adapter manually, as described in Chapter 14.

public enum MissingMappingAction { Passthrough = 1 , Ignore = 2 , Error = 3 }
