DateTimeFormatInfo.ShortestDayNames Свойство

Определение

Возвращает или задает массив строк самых кратких уникальных сокращений имен дней, связанный с текущим объектом DateTimeFormatInfo.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()

Значение свойства

String[]

Массив строк имен дней.A string array of day names.

Атрибуты

Исключения

В операции присваивания массив не имеет ровно семь элементов.In a set operation, the array does not have exactly seven elements.

В наборе операций массив значений или один из элементов массива значений имеет значение null.In a set operation, the value array or one of the elements of the value array is null.

В операции задания текущий объект DateTimeFormatInfo доступен только для чтения.In a set operation, the current DateTimeFormatInfo object is read-only.

Примеры

В следующем примере показаны несколько методов и свойств, задающих шаблоны формата даты и времени, имя собственного календаря, а также полные и сокращенные названия месяца и дня.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.
