DateTimeFormatInfo.GetEra-Methode
Gibt die Ganzzahl zurück, die den angegebenen Zeitraum darstellt.
Namespace: System.Globalization
Assembly: mscorlib (in mscorlib.dll)
Syntax
'Declaration
Public Function GetEra ( _
eraName As String _
) As Integer
'Usage
Dim instance As DateTimeFormatInfo
Dim eraName As String
Dim returnValue As Integer
returnValue = instance.GetEra(eraName)
public int GetEra (
string eraName
)
public:
int GetEra (
String^ eraName
)
public int GetEra (
String eraName
)
public function GetEra (
eraName : String
) : int
Parameter
- eraName
Die Zeichenfolge mit dem Namen des Zeitraums.
Rückgabewert
Die Ganzzahl, die den Zeitraum darstellt, wenn eraName gültig ist, andernfalls -1.
Ausnahmen
| Ausnahmetyp | Bedingung |
|---|---|
eraName ist NULL (Nothing in Visual Basic). |
Hinweise
Der Name des Zeitraums ist der Name, der in einem Kalender für eine Zeitspanne verwendet wird, die von einem festgelegten Zeitpunkt oder Ereignis an gerechnet wird. Beispielsweise bezeichnet "A.D." bzw. "u.Z." den aktuellen Zeitraum im gregorianischen Kalender.
Beim Vergleich mit eraName wird die Groß- und Kleinschreibung nicht berücksichtigt, z. B. stimmt "A.D." mit "a.d." überein.
GetEra ignoriert die Interpunktion in abgekürzten Zeitraumnamen nur dann, wenn der GregorianCalendar in DateTimeFormatInfo.Calendar ausgewählt ist und die Kultur "A.D." als Namen des Zeitraums verwendet, d. h., "A.D." ist äquivalent zu "AD".
GetEra vergleicht eraName mit dem vollständigen, von GetEraName zurückgegebenen Namen des Zeitraums und mit dem abgekürzten, von GetAbbreviatedEraName zurückgegebenen Namen des Zeitraums.
Beispiel
Im folgenden Codebeispiel wird veranschaulicht, dass DateTimeFormatInfo die Interpunktion im Namen des Zeitraums nur dann ignoriert, wenn es sich um den gregorianischen Kalender handelt und die Kultur den Zeitraumnamen "A.D." verwendet.
