DateTimeFormatInfo.GetEra Method
Returns the integer representing the specified era.
Namespace: System.Globalization
Assembly: mscorlib (in mscorlib.dll)
Parameters
- eraName
- Type: System.String
The string containing the name of the era.
| Exception | Condition |
|---|---|
| ArgumentNullException | eraName is null. |
The era name is the name a calendar uses to refer to a period of time reckoned from a fixed point or event. For example, "A.D." or "C.E." is the current era in the Gregorian calendar.
The comparison with eraName is case-insensitive, for example, "A.D." is equivalent to "a.d.".
GetEra ignores punctuation in abbreviated era names, only if the GregorianCalendar is selected in DateTimeFormatInfo.Calendar and the culture uses "A.D." as the era name, that is, "A.D." is equivalent to "AD".
GetEra compares eraName with the full era name returned by GetEraName and with the abbreviated era name returned by GetAbbreviatedEraName.
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 System; using System.Globalization; public class SamplesGregorianCalendar { public static void 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" ); foreach ( CultureInfo myCI in CultureInfo.GetCultures( CultureTypes.SpecificCultures ) ) { 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(); } } } /* This code produces the following output. This output has been cropped for brevity. ----- AD ----- ----- CE ----- CULTURE PUNC NO PUNC PUNC NO PUNC CALENDAR ar-SA -1 -1 -1 -1 System.Globalization.HijriCalendar ar-IQ 1 1 -1 -1 System.Globalization.GregorianCalendar ar-EG 1 1 -1 -1 System.Globalization.GregorianCalendar ar-LY 1 1 -1 -1 System.Globalization.GregorianCalendar ar-DZ 1 1 -1 -1 System.Globalization.GregorianCalendar ar-MA 1 1 -1 -1 System.Globalization.GregorianCalendar ar-TN 1 1 -1 -1 System.Globalization.GregorianCalendar ar-OM 1 1 -1 -1 System.Globalization.GregorianCalendar ar-YE 1 1 -1 -1 System.Globalization.GregorianCalendar ar-SY 1 1 -1 -1 System.Globalization.GregorianCalendar ar-JO 1 1 -1 -1 System.Globalization.GregorianCalendar ar-LB 1 1 -1 -1 System.Globalization.GregorianCalendar ar-KW 1 1 -1 -1 System.Globalization.GregorianCalendar ar-AE 1 1 -1 -1 System.Globalization.GregorianCalendar ar-BH 1 1 -1 -1 System.Globalization.GregorianCalendar ar-QA 1 1 -1 -1 System.Globalization.GregorianCalendar bg-BG 1 1 -1 -1 System.Globalization.GregorianCalendar ca-ES -1 -1 -1 -1 System.Globalization.GregorianCalendar zh-TW -1 -1 -1 -1 System.Globalization.GregorianCalendar zh-CN -1 -1 -1 -1 System.Globalization.GregorianCalendar zh-HK -1 -1 -1 -1 System.Globalization.GregorianCalendar zh-SG 1 1 -1 -1 System.Globalization.GregorianCalendar zh-MO 1 1 -1 -1 System.Globalization.GregorianCalendar cs-CZ -1 -1 -1 -1 System.Globalization.GregorianCalendar da-DK 1 1 -1 -1 System.Globalization.GregorianCalendar */
