Restituisce il tipo di una matrice il cui tipo di elemento è il parametro di tipo generico.
Overload
| MakeArrayType(Int32) |
Restituisce il tipo di una matrice il cui tipo di elemento è il parametro di tipo generico con il numero di dimensioni specificato. |
| MakeArrayType() |
Restituisce il tipo di una matrice unidimensionale il cui tipo di elemento è il parametro di tipo generico. |
- Origine:
- GenericTypeParameterBuilder.cs
Restituisce il tipo di una matrice il cui tipo di elemento è il parametro di tipo generico con il numero di dimensioni specificato.
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 TypeParametri
- rank
- Int32
Numero di dimensioni della matrice.
Restituisce
Oggetto Type che rappresenta il tipo di una matrice il cui tipo di elemento è il parametro di tipo generico con il numero di dimensioni specificato.
Eccezioni
rank non è un numero di dimensioni valido. Ad esempio, il relativo valore è minore di 1.
Esempio
Nell'esempio di codice seguente viene creato un modulo dinamico, un tipo generico astratto denominato Sample con un parametro di tipo, Te un metodo astratto denominato TestMethod.
TestMethod accetta un ref parametro (ByRef in Visual Basic) di tipo T, un puntatore al tipo Te una matrice di T. Questo metodo restituisce una matrice bidimensionale di T. L'esempio di codice salva il modulo dinamico su disco, quindi è possibile esaminarlo usando il disassembler MSIL (Ildasm.exe).
