'Declaration
Public Property MonthGenitiveNames As String()

Property Value

In some languages, a month name that is part of a date appears in the genitive case.. For example, a date in the Russian (Russia) or "ru-RU" culture consists of the day number and the genitive month name, such as 1 Января.

If you set the MonthGenitiveNames property, you must also set the MonthNames property.

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.
