Retourne le type d’un tableau dont le type d’élément est le paramètre de type générique.
| MakeArrayType(Int32) |
Retourne le type d’un tableau dont le type des éléments correspond au paramètre de type générique, avec le nombre spécifié de dimensions. |
| MakeArrayType() |
Retourne le type d’un tableau unidimensionnel dont le type d’élément est le paramètre de type générique. |
Retourne le type d’un tableau dont le type des éléments correspond au paramètre de type générique, avec le nombre spécifié de dimensions.
public:
override Type ^ MakeArrayType(int rank);C#
public override Type MakeArrayType(int rank);override this.MakeArrayType : int -> TypePublic Overrides Function MakeArrayType (rank As Integer) As TypeParamètres
- rank
- Int32
Nombre de dimensions pour le tableau.
Retours
Objet Type qui représente le type d’un tableau dont le type des éléments correspond au paramètre de type générique, avec le nombre spécifié de dimensions.
Exceptions
rank n’est pas un nombre de dimensions valide. Par exemple, sa valeur est inférieure à 1.
Exemples
L’exemple de code suivant crée un module dynamique, un type générique abstrait nommé Sample avec un paramètre de type , Tet une méthode abstraite nommée TestMethod.
TestMethod prend un ref paramètre (ByRef en Visual Basic) de type T, un pointeur vers le type Tet un tableau de T. Cette méthode retourne un tableau à deux dimensions de T. L’exemple de code enregistre le module dynamique sur le disque afin que vous puissiez l’examiner à l’aide du désassembleur MSIL (Ildasm.exe).
