Name
DataColumnMapping
Synopsis
This class represents a mapping between a field (or column) name in
the data source (SourceColumn
) and the field name
in the System.Data.DataSet
(DataSetColumn
). The data source column name is
case-sensitive, while the System.Data.DataSet
column name isn’t.
Column mappings are applied to the DataAdapter
you
use to transfer information. Column mappings work in both directions:
in other words, the DataAdapter
automatically maps
the column when filling it with the appropriate data and can apply
any changes back to the original data source column during updates.
Column mappings are never added independently to a
DataAdapter
; instead, they are added to a
DataTableMapping
, which can then be added to the
DataAdapter.TableMappings
collection.
