次の例では、派生クラスを作成 OleDbDataAdapter し、そのプロパティの一部を設定します。

// Assumes a valid connection string to an Access database.
static void CreateOleDbAdapter(string connectionString)
{
    OleDbDataAdapter adapter = new OleDbDataAdapter();
    adapter.SelectCommand =
        new OleDbCommand("SELECT * FROM Categories ORDER BY CategoryID");
    adapter.SelectCommand.Connection =
        new OleDbConnection(connectionString);
    adapter.MissingMappingAction = MissingMappingAction.Error;
    adapter.MissingSchemaAction = MissingSchemaAction.Error;
}
' Assumes a valid connection string to an Access database.
Private Sub CreateOleDbDataAdapter(ByVal connectionString As String)
    Dim adapter As New OleDbDataAdapter()
    adapter.SelectCommand = _
       New OleDbCommand("SELECT * FROM Categories ORDER BY CategoryID")
    adapter.SelectCommand.Connection = New OleDbConnection _
       (connectionString)
    adapter.MissingMappingAction = MissingMappingAction.Error
    adapter.MissingSchemaAction = MissingSchemaAction.Error
End Sub
