ITableMappingCollection Interface

Contains a collection of TableMapping objects, and is implemented by the DataTableMappingCollection, which is used in common by .NET Framework data providers.

For a list of all members of this type, see ITableMappingCollection Members.

[Visual Basic]
Public Interface ITableMappingCollection
   Inherits IList, ICollection, IEnumerable
[C#]
public interface ITableMappingCollection : IList, ICollection,
   IEnumerable
[C++]
public __gc __interface ITableMappingCollection : public IList,
   ICollection, IEnumerable
[JScript]
public interface ITableMappingCollection implements IList,
   ICollection, IEnumerable

Classes that Implement ITableMappingCollection

Class Description
DataTableMappingCollection A collection of DataTableMapping objects. This class cannot be inherited.

Remarks

The ITableMappingCollection interface allows an inheriting class to implement a TableMapping collection. For more information, see Setting Up DataTable and DataColumn Mappings.

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.

Example

[Visual Basic, C#, C++] 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.

[Visual Basic] 
Public Sub AddDataTableMapping()
    ' ...
    ' create myTableMappings
    ' ...
    Dim myNewMapping As New DataTableMapping("Categories", "DataCategories")
    myTableMappings.Add(CType(myNewMapping, Object))
    MessageBox.Show("Table " + myNewMapping.ToString() + " added to " _
       + "table mapping collection " + myTableMappings.ToString())
End Sub

[C#] 
public void AddDataTableMapping() {
   // ...
   // create myTableMappings
   // ...
   DataTableMapping myNewMapping =
      new DataTableMapping("Categories","DataCategories");
   myTableMappings.Add((Object) myNewMapping);
   MessageBox.Show("Table " + myNewMapping.ToString() + " added to " +
      "table mapping collection " + myTableMappings.ToString());
}

[C++] 
void AddDataTableMapping() {
   // ...
   // create myTableMappings
   // ...
   DataTableMapping* myNewMapping =
      new DataTableMapping(S"Categories",S"DataCategories");
   myTableMappings->Add(static_cast<Object*>(myNewMapping));
   MessageBox::Show(String::Concat( S"Table ", myNewMapping->ToString(), S" added to ",
      S"table mapping collection ", myTableMappings->ToString() ));
}
