ADO.NET in a Nutshell

Name

DataTableMapping

Synopsis

This class represents a mapping between a table name in the data source (SourceTable) and the table name in the System.Data.DataSet (DataSetTable). The data source table name is case-sensitive, while the System.Data.DataSet table name isn’t. A third property, DataColumnMappingCollection, contains all field-name mappings for the table. Column and table name mappings aren’t required (by default, ADO.NET simply uses the data source names), but they do add that an extra layer of indirection.

Table mappings are applied to the DataAdapter. Table mappings work in both directions: when filling a table and when updating it. You add a table mapping to a DataAdapter by inserting the appropriate DataTableMapping into the DataAdapter.TableMappings collection.
