Assembly: mscorlib (in mscorlib.dll)
| Member name | Description | |
|---|---|---|
| Arabic | Refers to the Arabic version of the Gregorian calendar. | |
| Localized | Refers to the localized version of the Gregorian calendar, based on the language of the CultureInfo object that uses the DateTimeFormatInfo object. | |
| MiddleEastFrench | Refers to the Middle East French version of the Gregorian calendar. | |
| TransliteratedEnglish | Refers to the transliterated English version of the Gregorian calendar. | |
| TransliteratedFrench | Refers to the transliterated French version of the Gregorian calendar. | |
| USEnglish | Refers to the U.S. English version of the Gregorian calendar. |
The date and time patterns associated with the GregorianCalendar vary depending on the culture. If the value of the CultureInfo.Calendar property of a particular culture is GregorianCalendar, or if the value of one of the calendars in a culture’s CultureInfo.OptionalCalendars property array is GregorianCalendar, that object’s GregorianCalendar.CalendarType property is a GregorianCalendarTypes enumeration value that specifies which date and time patterns that culture uses.
For example, most of the Arabic cultures support the following versions of the Gregorian calendar:
A localized version, indicated by a GregorianCalendar.CalendarType,value of GregorianCalendarTypes.Localized.
An English version, indicated by a GregorianCalendar.CalendarType,value of GregorianCalendarTypes.USEnglish.
A French version, indicated by a GregorianCalendar.CalendarType,value of GregorianCalendarTypes.MiddleEastFrench.
A culture that supports GregorianCalendar might not support all language versions of GregorianCalendar. The CultureInfo.Calendar and CultureInfo.OptionalCalendars properties specify the calendars supported by that culture. If GregorianCalendar is supported, CalendarType can be used to determine which language versions of GregorianCalendar are supported.
The following example demonstrates how to determine the GregorianCalendar language version supported by the culture.
Imports System.Globalization Public Class Example Public Shared Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock) ' Gets the calendars supported by the ar-SA culture. Dim myOptCals As Calendar() = New CultureInfo("ar-SA").OptionalCalendars ' Checks which ones are GregorianCalendar then determines the GregorianCalendar version. outputBlock.Text &= "The ar-SA culture supports the following calendars:" & vbCrLf Dim cal As Calendar For Each cal In myOptCals If cal.GetType() Is GetType(GregorianCalendar) Then Dim myGreCal As GregorianCalendar = CType(cal, GregorianCalendar) Dim calType As GregorianCalendarTypes = myGreCal.CalendarType outputBlock.Text += String.Format(" {0} ({1})", cal, calType) & vbCrLf Else outputBlock.Text += String.Format(" {0}", cal) & vbCrLf End If Next cal End Sub 'Main End Class 'SamplesCultureInfo 'This code produces the following output. ' 'The ar-SA culture supports the following calendars: ' System.Globalization.HijriCalendar ' System.Globalization.GregorianCalendar (USEnglish) ' System.Globalization.GregorianCalendar (MiddleEastFrench) ' System.Globalization.GregorianCalendar (Arabic) ' System.Globalization.GregorianCalendar (Localized) ' System.Globalization.GregorianCalendar (TransliteratedFrench)
The following example displays a DateTime value using a localized GregorianCalendar object.
Imports System.Globalization Public Class Example Public Shared Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock) ' Creates and initializes four different CultureInfo objects. Dim myCIdeDE As New CultureInfo("de-DE") Dim myCIenUS As New CultureInfo("en-US") Dim myCIfrFR As New CultureInfo("fr-FR") Dim myCIruRU As New CultureInfo("ru-RU") ' Creates a Localized GregorianCalendar. ' GregorianCalendarTypes.Localized is the default when using the GregorianCalendar constructor without parameters. Dim myCal = New GregorianCalendar() ' Sets the DateTimeFormatInfo.Calendar property to a Localized GregorianCalendar. ' Localized GregorianCalendar is the default calendar for de-DE, en-US, and fr-FR, myCIruRU.DateTimeFormat.Calendar = myCal ' Creates a DateTime. Dim myDT As New DateTime(2002, 1, 3, 13, 30, 45) ' Displays the DateTime. outputBlock.Text += String.Format("de-DE: {0}", myDT.ToString("F", myCIdeDE)) & vbCrLf outputBlock.Text += String.Format("en-US: {0}", myDT.ToString("F", myCIenUS)) & vbCrLf outputBlock.Text += String.Format("fr-FR: {0}", myDT.ToString("F", myCIfrFR)) & vbCrLf outputBlock.Text += String.Format("ru-RU: {0}", myDT.ToString("F", myCIruRU)) & vbCrLf End Sub End Class ' The example displays the following output: ' de-DE: Donnerstag, 3. Januar 2002 13:30:45 ' en-US: Thursday, January 03, 2002 1:30:45 PM ' fr-FR: jeudi 3 janvier 2002 13:30:45 ' ru-RU: 3 января 2002 г. 13:30:45
