Overload

RegionInfo(Int32)

Menginisialisasi instans RegionInfo baru kelas berdasarkan negara/wilayah yang terkait dengan pengidentifikasi budaya yang ditentukan.
RegionInfo(String)

Menginisialisasi instans RegionInfo baru kelas berdasarkan negara/wilayah atau budaya tertentu, yang ditentukan berdasarkan nama.

public:
 RegionInfo(int culture);
public RegionInfo (int culture);
new System.Globalization.RegionInfo : int -> System.Globalization.RegionInfo
Public Sub New (culture As Integer)

Parameter

culture
Int32

Pengidentifikasi budaya.

Pengecualian

ArgumentException

culture menentukan budaya yang invarian, kustom, atau netral.

Keterangan

RegionInfo(String) adalah konstruktor yang direkomendasikan untuk membuat instans RegionInfo objek. RegionInfo(Int32) Tidak seperti konstruktor yang memerlukan pengidentifikasi budaya numerik sebagai parameter, parameternya adalah nama budaya atau kode negara yang lebih mudah dibaca.

Pengidentifikasi budaya dipetakan ke pengidentifikasi lokal Dukungan Bahasa Nasional (NLS) yang sesuai. Untuk informasi selengkapnya, lihat Referensi LCID Windows.

Nilai Name properti objek baru RegionInfo yang dibuat dengan memanggil konstruktor ini adalah kode ISO 3166 2 huruf untuk negara/wilayah, bukan bahasa gabungan dan kode negara/wilayah. Misalnya, jika objek RegionInfo dibuat dengan pengidentifikasi budaya 0x0409 untuk budaya Inggris (Amerika Serikat), nilai Name properti adalah "AS". Sebaliknya, jika RegionInfo objek dibuat dengan kode en-US bahasa dan negara/wilayah gabungan untuk budaya Inggris (Amerika Serikat), nilai Name properti adalah "en-US" dalam .NET Framework dan hanya "US" di .NET Core dan .NET 5+.

public:
 RegionInfo(System::String ^ name);
public RegionInfo (string name);
new System.Globalization.RegionInfo : string -> System.Globalization.RegionInfo
Public Sub New (name As String)

Parameter

name
String

String yang berisi kode dua huruf yang ditentukan dalam ISO 3166 untuk negara/wilayah.

-atau-

String yang berisi nama budaya untuk budaya tertentu, budaya kustom, atau budaya khusus Windows. Jika nama budaya tidak dalam format RFC 4646, aplikasi Anda harus menentukan seluruh nama budaya alih-alih hanya negara/wilayah.

Pengecualian

ArgumentNullException

nameadalah null.

ArgumentException

name bukan nama negara/wilayah yang valid atau nama budaya tertentu.

Keterangan

Parameter name adalah salah satu kode yang ditentukan untuk negara/wilayah, atau nama budaya tertentu, kustom, atau khusus Windows. Kasus tidak signifikan. Namun, Nameproperti , TwoLetterISORegionName, dan ThreeLetterISORegionName mengembalikan kode atau nama budaya yang ditentukan dalam huruf besar.

Nama yang telah RegionInfo ditentukan sebelumnya tercantum dalam KODE ISO 3166: Negara.

Anda harus memberikan nama budaya tertentu daripada hanya nama negara/wilayah dalam name parameter . Misalnya, en-US untuk bahasa Inggris (Amerika Serikat) atau es-US untuk Bahasa Spanyol (Amerika Serikat) lebih disukai US karena properti seperti NativeName dan CurrencyNativeName mencerminkan bahasa tertentu. az-Latn-AZ atau az-Cyrl-AZ lebih disukai AZ karena properti seperti NativeName, CurrencyNativeName, dan CurrencySymbol mencerminkan skrip tertentu. Nama budaya yang telah ditentukan sebelumnya tercantum di referensi Windows LCID.

Konstruktor ini melemparkan ArgumentException jika name adalah budaya netral (seperti en untuk bahasa Inggris).

Catatan Bagi Pemanggil

Konstruktor ini hanya menerima budaya atau kode negara/wilayah tertentu. Namun, beberapa nama budaya netral sama dengan kode negara/wilayah. Dalam hal ini, name ditafsirkan sebagai kode negara/wilayah daripada nama budaya netral, dan konstruktor ini tidak melempar ArgumentException.
