新しいオブジェクトが追加される先のコンテナー。

dataType
Type

名前を受け取るオブジェクトのデータ型。

戻り値

データ型の一意の名前。

次のコード例では、メソッドの実装例 INameCreationService.CreateName を示します。 メソッドは、指定したコンテナー内のコンポーネントの名前に固有の、指定した型の名前に基づいて名前を作成できます。

注釈

このメソッドは、指定したコンテナー内で一意の新しいオブジェクトの名前を返します。

注意 (実装者)

この種類のサービスは、多くの場合、データ型の名前から一意のオブジェクト名を作成するために実装されます。多くの場合、名前を一意識別子にできる番号が付加されます。 たとえば、 ListBox1 オブジェクトの場合です ListBox
