Определение

Пространство имен:

System.Globalization

Сборка:

System.Runtime.dll

Исходный код:

DateTimeFormatInfo.cs

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

public:
 property cli::array <System::String ^> ^ ShortestDayNames { cli::array <System::String ^> ^ get(); void set(cli::array <System::String ^> ^ value); };

public string[] ShortestDayNames { get; set; }

member this.ShortestDayNames : string[] with get, set

Public Property ShortestDayNames As String()

Значение свойства

String[]

Массив строк имен дней.

Исключения

ArgumentException

В операции присваивания массив не имеет ровно семь элементов.

ArgumentNullException

В наборе операций массив значений или один из элементов массива значений имеет значение null.

InvalidOperationException

В операции задания текущий объект DateTimeFormatInfo доступен только для чтения.

Примеры

В следующем примере показано несколько методов и свойств, которые задают шаблоны формата даты и времени, собственное название календаря, а также полные и сокращенные названия месяцев и дней.
