GenericTypeParameterBuilder.MakeArrayType Metode

Definisi

Ruang nama:

System.Reflection.Emit

Rakitan:

System.Reflection.Emit.dll

Mengembalikan jenis array yang jenis elemennya adalah parameter jenis generik.

Overload

MakeArrayType(Int32)	Mengembalikan jenis array yang jenis elemennya adalah parameter jenis generik, dengan jumlah dimensi yang ditentukan.
MakeArrayType()	Mengembalikan jenis array satu dimensi yang jenis elemennya adalah parameter jenis generik.

MakeArrayType(Int32)

Mengembalikan jenis array yang jenis elemennya adalah parameter jenis generik, dengan jumlah dimensi yang ditentukan.

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

Parameter

rank

Int32

Jumlah dimensi untuk array.

Mengembalikan

Type

Objek Type yang mewakili jenis array yang jenis elemennya adalah parameter jenis generik, dengan jumlah dimensi yang ditentukan.

Pengecualian

IndexOutOfRangeException

rank bukan jumlah dimensi yang valid. Misalnya, nilainya kurang dari 1.

Contoh

Contoh kode berikut membuat modul dinamis, jenis generik abstrak bernama Sample dengan satu parameter jenis, T, dan metode abstrak bernama TestMethod. TestMethod ref mengambil parameter (ByRef dalam Visual Basic) dari jenis T, pointer untuk mengetik T, dan array dari T. Metode ini mengembalikan array dua dimensi .T Contoh kode menyimpan modul dinamis ke disk, sehingga Anda dapat memeriksanya menggunakan MSIL Disassembler (Ildasm.exe).
