定義

DataColumnMappingCollection の派生 DataTable を取得します。Gets the derived DataColumnMappingCollection for the DataTable.

public:
 property System::Data::IColumnMappingCollection ^ ColumnMappings { System::Data::IColumnMappingCollection ^ get(); };
public System.Data.IColumnMappingCollection ColumnMappings { get; }
member this.ColumnMappings : System.Data.IColumnMappingCollection
Public ReadOnly Property ColumnMappings As IColumnMappingCollection

プロパティ値

データ列マップのコレクション。A collection of data column mappings.

次の例は、派生クラスのインスタンスを作成します。 DataTableMapping、そのプロパティ、およびコピーの一部を設定、ColumnMappingsを配列にします。The following example creates an instance of the derived class, DataTableMapping, sets some of its properties, and copies its ColumnMappings to an array. この例では、DataColumnMappingCollectionが作成されました。This example assumes that a DataColumnMappingCollection has been created.

public void CreateDataTableMapping() 
{
    // ...
    // create mappings
    // ...
    DataColumnMapping[] columns = {};
    // Copy mappings to array    
    mappings.CopyTo(columns, 0);
    DataTableMapping mapping =
        new DataTableMapping("Categories", "DataCategories", columns);    
}
Public Sub CreateDataTableMapping()
    ' ...
    ' create mappings
    ' ...
    Dim columns() As DataColumnMapping
    ' Copy mappings to array
    mappings.CopyTo(columns, 0)
    Dim mapping As New DataTableMapping _
       ("Categories", "DataCategories", columns)
End Sub
