DateTimeFormatInfo.NativeCalendarName Property

Gets the native name of the calendar associated with the current DateTimeFormatInfo object.

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

'Declaration
<ComVisibleAttribute(False)> _
Public ReadOnly Property NativeCalendarName As String

Property Value

Type: System.String
The native name of the calendar used in the culture associated with the current DateTimeFormatInfo object if that name is available, or the empty string ("") if the native calendar name is not available.

Notes to Callers

If DateTimeFormatInfo.Calendar is the TaiwanCalendar but the Thread.CurrentCulture is not "zh-TW", then NativeCalendarName, GetEraName, and GetAbbreviatedEraName return an empty string ("").

The following example demonstrates several methods and properties that specify date and time format patterns, native calendar name, and full and abbreviated month and day names.


' This code example demonstrates the DateTimeFormatInfo  
' MonthGenitiveNames, AbbreviatedMonthGenitiveNames,  
' ShortestDayNames, and NativeCalendarName properties, and 
' the GetShortestDayName() and SetAllDateTimePatterns() methods.
