Mengembalikan bilangan bulat yang mewakili era yang ditentukan.

public:
 int GetEra(System::String ^ eraName);

public int GetEra (string eraName);

member this.GetEra : string -> int

Public Function GetEra (eraName As String) As Integer

Parameter

eraName: String

String yang berisi nama era.

Mengembalikan

Int32

Bilangan bulat yang mewakili era, jika eraName valid; jika tidak, -1.

Pengecualian

ArgumentNullException

eraNameadalah null.

Contoh

Contoh berikut menunjukkan bahwa DateTimeFormatInfo mengabaikan tanda baca dalam nama era, hanya jika kalender adalah Gregorian dan budaya menggunakan nama era "A.D.".

using namespace System;
using namespace System::Globalization;
using namespace System::Collections;
int main()
{
   
   // Creates strings with punctuation and without.
   String^ strADPunc = "A.D.";
   String^ strADNoPunc = "AD";
   String^ strCEPunc = "C.E.";
   String^ strCENoPunc = "CE";
   
   // Calls DTFI::GetEra for each culture that uses GregorianCalendar as the default calendar.
   Console::WriteLine( "            ----- AD -----  ----- CE -----" );
   Console::WriteLine( "CULTURE     PUNC   NO PUNC  PUNC   NO PUNC  CALENDAR" );
   IEnumerator^ en = CultureInfo::GetCultures( CultureTypes::SpecificCultures )->GetEnumerator();
   while ( en->MoveNext() )
   {
      CultureInfo^ myCI = safe_cast<CultureInfo^>(en->Current);
      Console::Write( "{0, -12}", myCI );
      Console::Write( "{0,-7}{1,-9}", myCI->DateTimeFormat->GetEra( strADPunc ), myCI->DateTimeFormat->GetEra( strADNoPunc ) );
      Console::Write( "{0, -7}{1, -9}", myCI->DateTimeFormat->GetEra( strCEPunc ), myCI->DateTimeFormat->GetEra( strCENoPunc ) );
      Console::Write( "{0}", myCI->Calendar );
      Console::WriteLine();
   }
}

Keterangan

Nama era adalah nama yang digunakan kalender untuk merujuk pada periode waktu yang diperhitungkan dari titik atau acara tetap. Misalnya, "A.D." atau "C.E." adalah era saat ini di kalender Gregorian.

Perbandingan dengan tidak peka huruf besar/kecil, misalnya, "A.D." setara dengan eraName "a.d.".

GetEra mengabaikan tanda baca dalam nama era yang disingkat, hanya jika GregorianCalendar dipilih di DateTimeFormatInfo.Calendar dan budaya menggunakan "A.D." sebagai nama era, yaitu, "A.D." setara dengan "AD".

GetErabandingkan dengan nama era lengkap yang dikembalikan oleh GetEraName dan dengan nama era yang disingkat eraName yang dikembalikan oleh GetAbbreviatedEraName.

Penting

Era di kalender Jepang didasarkan pada pemerintahan kaisar dan karenanya diharapkan berubah. Misalnya, 1 Mei 2019 menandai awal era Reiwa di JapaneseCalendar dan JapaneseLunisolarCalendar. Perubahan era seperti itu mempengaruhi semua aplikasi yang menggunakan kalender ini. Untuk informasi selengkapnya dan untuk menentukan apakah aplikasi Anda terpengaruh, lihat Menangani era baru di kalender Jepang di .NET. Untuk informasi tentang menguji aplikasi Anda pada sistem Windows untuk memastikan kesiapannya untuk perubahan era, lihat Menyiapkan aplikasi Anda untuk perubahan era Jepang. Untuk fitur di .NET yang mendukung kalender dengan beberapa era dan untuk praktik terbaik saat bekerja dengan kalender yang mendukung beberapa era, lihat Bekerja dengan era.
