GregorianCalendarTypes Enumeration

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Defines the different language versions of the Gregorian calendar.

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

Syntax

'Declaration

Public Enumeration GregorianCalendarTypes

[ComVisibleAttribute(true)]
public enum GregorianCalendarTypes

Members

	Member name	Description
	Localized	Refers to the localized version of the Gregorian calendar, based on the language of the CultureInfo object that uses the DateTimeFormatInfo object.
	USEnglish	Refers to the U.S. English version of the Gregorian calendar.
	MiddleEastFrench	Refers to the Middle East French version of the Gregorian calendar.
	Arabic	Refers to the Arabic 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.

Remarks

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.

Examples

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.

   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {

      // Gets the calendars supported by the ar-SA culture.

      // Checks which ones are GregorianCalendar then determines the GregorianCalendar version.
      outputBlock.Text += "The ar-SA culture supports the following calendars:" + "\n";
      foreach (Calendar cal in myOptCals)
      {
         if (cal.GetType() == typeof(GregorianCalendar))
         {
            GregorianCalendar myGreCal = (GregorianCalendar)cal;

         }
      }

   }

}

The following example displays a DateTime value using a localized GregorianCalendar object.

      Dim myCal = New GregorianCalendar()

      ' Sets the DateTimeFormatInfo.Calendar property to a Localized GregorianCalendar.
