IColumnMapping Interface
Associates a data source column with a DataSet column, and is implemented by the DataColumnMapping class, which is used in common by .NET Framework data providers.
Assembly: System.Data (in System.Data.dll)
| Name | Description | |
|---|---|---|
 | DataSetColumn | Gets or sets the name of the column within the DataSet to map to. |
| SourceColumn | Gets or sets the name of the column within the data source to map from. The name is case-sensitive. |
The IColumnMapping interface enables an inheriting class to implement a Column Mapping 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 IColumnMapping interface directly, but creates an instance of a class that inherits IColumnMapping.
Classes that inherit IColumnMapping must implement all inherited members, and typically define additional members to add provider-specific functionality. For example, the IColumnMapping interface defines the DataSetColumn property. In turn, the DataColumnMapping class inherits this property, and also defines the GetDataColumnBySchemaAction method.
Notes to Implementers:
When you inherit from the IColumnMapping interface, you should implement the following constructors:
Item | Description |
|---|---|
ColumnMapping() | Initializes a new instance of the ColumnMapping class. |
ColumnMapping(string sourceColumn, string dataSetColumn) | Initializes a new instance of the ColumnMapping class with a source with the specified source column name and DataSet column name. |
The following example creates an instance of the derived class, DataColumnMapping, and adds it to a DataColumnMappingCollection collection. It then tells the user that the mapping was added to the collection and shows the parent for the mapping.
