ITableMappingCollection Interface
Contains a collection of TableMapping objects, and is implemented by the DataTableMappingCollection, which is used in common by .NET Framework data providers.
Assembly: System.Data (in System.Data.dll)
The ITableMappingCollection interface allows an inheriting class to implement a TableMapping collection. For more information, see DataAdapter DataTable and DataColumn Mappings (ADO.NET).
An application does not create an instance of the ITableMappingCollection interface directly, but creates an instance of a class that inherits ITableMappingCollection.
Classes that inherit ITableMappingCollection must implement the inherited members, and typically define additional members to add provider-specific functionality. For example, the ITableMappingCollection interface defines one implementation of 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 ITableMappingCollection interface, you should implement the following constructor:
Item | Description |
|---|---|
PrvTableMappingCollection() | Creates an empty PrvTableMappingCollection class. |
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.
Public Sub AddDataTableMapping() ' ... ' create tableMappings ' ... Dim mapping As New DataTableMapping( _ "Categories", "DataCategories") tableMappings.Add(CType(mapping, Object)) Console.WriteLine( _ "Table {0} added to {1} table mapping collection.", _ mapping.ToString(), tableMappings.ToString()) End Sub
