DateTimeFormatInfo.GetEra Method

Returns the integer representing the specified era.

Namespace:  System.Globalization
Assembly:  mscorlib (in mscorlib.dll)

member GetEra : 
        eraName:string -> int


Type: System.String

The string containing the name of the era.

Return Value

Type: System.Int32
The integer representing the era, if eraName is valid; otherwise, -1.


eraName is a null reference (Nothing in Visual Basic).

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.".
