ITableMappingCollection ITableMappingCollection ITableMappingCollection ITableMappingCollection Interface

定義

含有 TableMapping 物件的集合,並且是由 .NET Framework 資料提供者 (Data Provider) 共同使用的 DataTableMappingCollection 所實作。Contains a collection of TableMapping objects, and is implemented by the DataTableMappingCollection, which is used in common by .NET Framework data providers.

public interface class ITableMappingCollection : System::Collections::IList
public interface ITableMappingCollection : System.Collections.IList
type ITableMappingCollection = interface
    interface IList
    interface ICollection
    interface IEnumerable
Public Interface ITableMappingCollection
Implements IList

範例

下列範例會建立衍生類別中的執行個體DataTableMapping,並將它加入DataTableMappingCollection集合。The following example creates an instance of the derived class, DataTableMapping, and adds it to a DataTableMappingCollection collection. 它接著會通知使用者對應已經加入至集合。It then informs the user that the mapping was added to the collection.

public void AddDataTableMapping() 
{
    // ...
    // create tableMappings
    // ...
    DataTableMapping mapping =
        new DataTableMapping("Categories","DataCategories");
    tableMappings.Add((Object) mapping);
    Console.WriteLine("Table {0} added to {1} table mapping collection.",
        mapping.ToString(), tableMappings.ToString());
}
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

備註

ITableMappingCollection介面可讓繼承的類別來實作 TableMapping 集合。The ITableMappingCollection interface allows an inheriting class to implement a TableMapping collection. 如需詳細資訊,請參閱 < DataAdapter DataTable 和 DataColumn 對應For more information, see DataAdapter DataTable and DataColumn Mappings.

應用程式不會建立的執行個體ITableMappingCollection介面直接,但建立繼承的類別的執行個體ITableMappingCollectionAn application does not create an instance of the ITableMappingCollection interface directly, but creates an instance of a class that inherits ITableMappingCollection.

繼承的類別ITableMappingCollection必須實作繼承的成員,並通常會定義要新增提供者特有的功能的其他成員。Classes that inherit ITableMappingCollection must implement the inherited members, and typically define additional members to add provider-specific functionality. 例如,ITableMappingCollection介面會定義的其中一個實作RemoveAt方法。For example, the ITableMappingCollection interface defines one implementation of the RemoveAt method. 依次DataTableMappingCollection類別會繼承這個方法,並定義兩個額外的多載的RemoveAtIn turn, the DataTableMappingCollection class inherits this method, and defines two additional overloads of RemoveAt.

給實施者的注意事項

當您繼承自ITableMappingCollection介面,您應該實作下列建構函式:When you inherit from the ITableMappingCollection interface, you should implement the following constructor:
