DateTimeFormatInfo.ShortestDayNames DateTimeFormatInfo.ShortestDayNames DateTimeFormatInfo.ShortestDayNames DateTimeFormatInfo.ShortestDayNames Property

Definizione

Ottiene o imposta una matrice di stringhe dei nomi univoci dei giorni abbreviati più corti associati all'oggetto DateTimeFormatInfo corrente.Gets or sets a string array of the shortest unique abbreviated day names associated with the current DateTimeFormatInfo object.

public:
 property cli::array <System::String ^> ^ ShortestDayNames { cli::array <System::String ^> ^ get(); void set(cli::array <System::String ^> ^ value); };
[System.Runtime.InteropServices.ComVisible(false)]
public string[] ShortestDayNames { get; set; }
member this.ShortestDayNames : string[] with get, set
Public Property ShortestDayNames As String()

Valore della proprietà

String[]

Matrice di stringhe dei nomi dei giorni.A string array of day names.

Eccezioni

In un'operazione set la matrice ha un numero di elementi diverso da sette.In a set operation, the array does not have exactly seven elements.

In un'operazione Set la matrice di valori o uno dei relativi elementi è null.In a set operation, the value array or one of the elements of the value array is null.

In un'operazione di impostazione l'oggetto DateTimeFormatInfo corrente è in sola lettura.In a set operation, the current DateTimeFormatInfo object is read-only.

Esempi

Nell'esempio seguente vengono illustrati diversi metodi e proprietà che specificano i modelli di formato di data e ora, il nome del calendario nativo e i nomi completi e abbreviati del mese e del giorno.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.
