DataColumnMapping marshal by reference

System.Data.Common (system.data.dll) sealed class

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.
