Belangrijk

Bepaalde informatie heeft betrekking op een voorlopige productversie die aanzienlijk kan worden gewijzigd voordat deze wordt uitgebracht. Microsoft biedt geen enkele expliciete of impliciete garanties met betrekking tot de informatie die hier wordt verstrekt.

Hiermee haalt u een tekenreeksmatrix op van de kortste verkorte dagnamen die aan het huidige DateTimeFormatInfo object zijn gekoppeld.

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

public string[] ShortestDayNames { get; set; }

[System.Runtime.InteropServices.ComVisible(false)]
public string[] ShortestDayNames { get; set; }

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

[<System.Runtime.InteropServices.ComVisible(false)>]
member this.ShortestDayNames : string[] with get, set

Public Property ShortestDayNames As String()

Waarde van eigenschap

String[]

Een tekenreeksmatrix met dagnamen.

Kenmerken: ComVisibleAttribute

Uitzonderingen

ArgumentException

In een setbewerking heeft de matrix niet precies zeven elementen.

ArgumentNullException

In een setbewerking is nullde waardematrix of een van de elementen van de waardematrix.

InvalidOperationException

In een setbewerking is het huidige DateTimeFormatInfo object alleen-lezen.

Voorbeelden

In het volgende voorbeeld ziet u verschillende methoden en eigenschappen waarmee datum- en tijdnotatiepatronen, systeemeigen kalendernaam en volledige en verkorte maand- en dagnamen worden opgegeven.

string[] myDateTimePatterns = ["MM/dd/yy", "MM/dd/yyyy"];

// Get the en-US culture.
CultureInfo ci = new("en-US");
// Get the DateTimeFormatInfo for the en-US culture.
DateTimeFormatInfo dtfi = ci.DateTimeFormat;

// Display the effective culture.
Console.WriteLine("This code example uses the {0} culture.", ci.Name);

// Display the native calendar name.
Console.WriteLine("\nNativeCalendarName...");
Console.WriteLine($"\"{dtfi.NativeCalendarName}\"");

// Display month genitive names.
Console.WriteLine("\nMonthGenitiveNames...");
foreach (string name in dtfi.MonthGenitiveNames)
{
    Console.WriteLine($"\"{name}\"");
}

// Display abbreviated month genitive names.
Console.WriteLine("\nAbbreviatedMonthGenitiveNames...");
foreach (string name in dtfi.AbbreviatedMonthGenitiveNames)
{
    Console.WriteLine($"\"{name}\"");
}

// Display shortest day names.
Console.WriteLine("\nShortestDayNames...");
foreach (string name in dtfi.ShortestDayNames)
{
    Console.WriteLine($"\"{name}\"");
}

// Display shortest day name for a particular day of the week.
Console.WriteLine("\nGetShortestDayName(DayOfWeek.Sunday)...");
Console.WriteLine($"\"{dtfi.GetShortestDayName(DayOfWeek.Sunday)}\"");

// Display the initial DateTime format patterns for the 'd' format specifier.
Console.WriteLine("\nInitial DateTime format patterns for the 'd' format specifier...");
foreach (string name in dtfi.GetAllDateTimePatterns('d'))
{
    Console.WriteLine($"\"{name}\"");
}

// Change the initial DateTime format patterns for the 'd' DateTime format specifier.
Console.WriteLine("\nChange the initial DateTime format patterns for the \n" +
                  "'d' format specifier to my format patterns...");
dtfi.SetAllDateTimePatterns(myDateTimePatterns, 'd');

// Display the new DateTime format patterns for the 'd' format specifier.
Console.WriteLine("\nNew DateTime format patterns for the 'd' format specifier...");
foreach (string name in dtfi.GetAllDateTimePatterns('d'))
{
    Console.WriteLine($"\"{name}\"");
}
