Sobrecargas

MakeArrayType(Int32)

Retorna o tipo de uma matriz cujo tipo de elemento é o parâmetro de tipo genérico, com o número de dimensões especificado.
MakeArrayType()

Retorna o tipo de uma matriz unidimensional cujo tipo de elemento é o parâmetro de tipo genérico.

MakeArrayType(Int32)

Origem:
GenericTypeParameterBuilder.cs

Retorna o tipo de uma matriz cujo tipo de elemento é o parâmetro de tipo genérico, com o número de dimensões especificado.

public:
 override Type ^ MakeArrayType(int rank);
public override Type MakeArrayType (int rank);
override this.MakeArrayType : int -> Type
Public Overrides Function MakeArrayType (rank As Integer) As Type

Parâmetros

rank
Int32

O número de dimensões da matriz.

Retornos

Type

Um objeto Type que representa o tipo de uma matriz cujo tipo de elemento é o parâmetro de tipo genérico, com o número de dimensões especificado.

Exceções

IndexOutOfRangeException

rank não é um número de dimensões válido. Por exemplo, seu valor é menor que 1.

Exemplos

O exemplo de código a seguir cria um módulo dinâmico, um tipo genérico abstrato chamado Sample com um parâmetro de tipo, Te um método abstrato chamado TestMethod. TestMethod usa um ref parâmetro (ByRef no Visual Basic) do tipo T, um ponteiro para o tipo Te uma matriz de T. Esse método retorna uma matriz bidimensional de T. O exemplo de código salva o módulo dinâmico em disco, para que você possa examiná-lo usando o Desmontador MSIL (Ildasm.exe).
