DateTimeFormatInfo.AbbreviatedMonthGenitiveNames Property

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

Gets or sets a string array of abbreviated month names associated with the current DateTimeFormatInfo object.

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

Syntax

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

[ComVisibleAttribute(false)]
public string[] AbbreviatedMonthGenitiveNames { get; set; }

Property Value

Type: array<System.String[]
A string array of abbreviated month names.

Exceptions

Exception	Condition
ArgumentException	In a set operation, the array is multidimensional or has a length that is not exactly 13.
ArgumentNullException	In a set operation, the value array or one of the elements of the value array is nulla null reference (Nothing in Visual Basic).
InvalidOperationException	The DateTimeFormatInfo object is read-only.

Remarks

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 (1 January).

In a set operation, the array must be one-dimensional and must have exactly 13 elements, because Calendar objects accommodate calendars with 13 months. For 12-month calendars, the thirteenth element should be String.Empty.

If you set the AbbreviatedMonthGenitiveNames property, you must also set the AbbreviatedMonthNames property.

Examples

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.
