Contains a collection of DataColumnMapping objects, and is implemented by the DataColumnMappingCollection, which is used in common by .NET Framework data providers.
Assembly: System.Data (in System.Data.dll)
The interface enables an inheriting class to implement a ColumnMapping collection. For more information, see DataAdapter DataTable and DataColumn Mappings (ADO.NET).
An application does not create an instance of the interface directly, but creates an instance of a class that inherits .
Classes that inherit must implement all inherited members, and typically define additional members to add provider-specific functionality. For example, the interface defines the RemoveAt method. In turn, the DataTableMappingCollection class inherits this method, and defines two additional overloads of RemoveAt.Notes to Implementers:
When you inherit from the interface, you should implement the following constructor:
Creates an empty ColumnMappingCollection class.
The following example uses an instance of the derived class, DataTableMapping, to Add several DataColumnMapping objects to its ColumnMappings collection, and then displays a list of those mapped source tables. This example assumes that a DataTableMapping has already been created.
