A DataColumnMapping enables you to use column names in a DataTable that are different from those in the data source. The DataAdapter uses the mapping to match the columns when the tables in the DataSet or data source are updated. For more information, see Setting Up DataTable and DataColumn Mappings.
The following example creates a DataColumnMapping object and adds it to a DataColumnMappingCollection. It then tells the user that the mapping was added to the collection and shows the Parent for the mapping.
Public Sub AddDataColumnMapping() ' ... ' create columnMappings ' ... Dim mapping As New DataColumnMapping( _ "Description", "DataDescription") columnMappings.Add(CType(mapping, Object)) Console.WriteLine("Column {0 added to column mapping collection {1.", _ mapping.ToString(), columnMappings.ToString()) End Sub
