public:
int GetEra(System::String ^ eraName);public int GetEra (string eraName);member this.GetEra : string -> intPublic Function GetEra (eraName As String) As IntegerParameter
- eraName
- String
Die Zeichenfolge mit dem Namen des Zeitraums.The string containing the name of the era.

Beispiele
Das folgende Beispiel zeigt, dass DateTimeFormatInfo die Interpunktions Zeichen im Namen des Zeitraums ignoriert, nur wenn der Kalender Gregorianisch ist und die Kultur den ERA-Namen "A.D." verwendet.The following example shows that DateTimeFormatInfo ignores the punctuation in the era name, only if the calendar is Gregorian and the culture uses the era name "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 );

Hinweise
Der Era-Name ist der Name, den ein Kalender verwendet, um auf einen Zeitraum zu verweisen, der von einem bestimmten Punkt oder Ereignis abgerechnet wird.The era name is the name a calendar uses to refer to a period of time reckoned from a fixed point or event. Beispiel: "A.D."For example, "A.D." oder "or "C.E." der aktuelle Zeitraum im gregorianischen Kalender.is the current era in the Gregorian calendar.
Beim Vergleich mit eraName wird die Groß-/Kleinschreibung nicht beachtet, z. b. "A.D."The comparison with eraName is case-insensitive, for example, "A.D." entspricht "a.d.".is equivalent to "a.d.".
GetEra ignoriert Interpunktions Zeichen in abgekürzten Zeit Namen, nur wenn GregorianCalendar in ausgewählt ist DateTimeFormatInfo.Calendar und die Kultur "A.D." verwendet.GetEra ignores punctuation in abbreviated era names, only if the GregorianCalendar is selected in DateTimeFormatInfo.Calendar and the culture uses "A.D." als Era-Name, d. h. "A.D."as the era name, that is, "A.D." entspricht "AD".is equivalent to "AD".
GetEravergleicht eraName den vollständigen ERA-Namen, der von zurückgegeben wird, GetEraName mit dem abgekürzten Zeit Namen, der von GetAbbreviatedEraNameGetEra compares eraName with the full era name returned by GetEraName and with the abbreviated era name returned by GetAbbreviatedEraName.
Wichtig
Die Zeitrechnung in japanischen Kalendern basiert auf den Regierungsperioden der Kaiser und wird sich daher erwartungsgemäß ändern.Eras in the Japanese calendars are based on the emperor's reign and are therefore expected to change. Beispiel: Der 1. Mai 2019 markiert den Beginn des Reiwa-Zeitabschnitts in den Kalendern des Typs JapaneseCalendar und JapaneseLunisolarCalendar.For example, May 1, 2019 marked the beginning of the Reiwa era in the JapaneseCalendar and JapaneseLunisolarCalendar. Eine derartige Änderung der Zeitabschnitte betrifft alle Anwendungen, die diese Kalender verwenden.Such a change of era affects all applications that use these calendars. Unter Handling a new era in the Japanese calendar in .NET (Umgang mit einem neuen Zeitabschnitt im japanischen Kalender in .NET) finden Sie weiter Informationen und wie Sie bestimmen können, ob Ihre Anwendungen ebenfalls betroffen sind.See Handling a new era in the Japanese calendar in .NET for more information and to determine whether your applications are affected. Unter Prepare your application for the Japanese era change (Vorbereiten Ihrer Anwendung für die Änderung des Zeitabschnitts im japanischen Kalender) finden Sie Informationen zum Testen Ihrer Anwendungen auf Windows-Systemen, um deren Bereitschaft für die Änderung im Zeitabschnitt sicherzustellen.See Prepare your application for the Japanese era change for information on testing your applications on Windows systems to ensure their readiness for the era change. Unter Arbeiten mit Zeiträumen finden Sie Informationen zu Funktionen in .NET, die Kalender mit mehreren Zeitabschnitten unterstützen, sowie bewährte Vorgehensweisen bei der Arbeit mit solchen Kalendern.See Working with eras for features in .NET that support calendars with multiple eras and for best practices when working with calendars that support multiple eras.
