ITableMapping Interface
Associates a source table with a table in a DataSet, and is implemented by the DataTableMapping class, which is used in common by .NET Framework data providers.
Assembly: System.Data (in System.Data.dll)
| Name | Description | |
|---|---|---|
 | ColumnMappings | Gets the derived DataColumnMappingCollection for the DataTable. |
| DataSetTable | Gets or sets the case-insensitive name of the table within the DataSet. |
| SourceTable | Gets or sets the case-sensitive name of the source table. |
The ITableMapping interface allows an inheriting class to implement a TableMapping class, which associates a data source column with a DataSet column. For more information, see DataAdapter DataTable and DataColumn Mappings.
An application does not create an instance of the ITableMapping interface directly, but creates an instance of a class that inherits ITableMapping.
Classes that inherit ITableMapping must implement the inherited members, and typically define additional members to add provider-specific functionality. For example, the ITableMapping interface defines the DataSetTable property. In turn, the DataTableMapping class inherits this property, and also defines the GetDataTableBySchemaAction method.
Notes to Implementers:
When you inherit from the ITableMapping interface, you should implement the following constructors:
Item | Description |
|---|---|
DataTableMapping() | Initializes a new instance of the TableMapping class. |
TableMapping(string sourceTable, string dataSetTable) | Initializes a new instance of the TableMapping class with a source when given a source table name and a DataTable name. |
TableMapping(string sourceTable, string dataSetTable, DataColumnMapping[] columnMappings) | Initializes a new instance of the TableMapping class when given a source table name, a DataTable name, and an array of ColumnMapping objects. |
The following example creates an instance of the derived class, DataTableMapping, and adds it to a DataTableMappingCollection collection. It then informs the user that the mapping was added to the collection and displays the parent mapping.
