DateTime.ToLongTimeString Metodo

Definizione

Converte il valore dell'oggetto DateTime corrente nell'equivalente rappresentazione di stringa dell'ora estesa.

public:
 System::String ^ ToLongTimeString();
public string ToLongTimeString ();
member this.ToLongTimeString : unit -> string
Public Function ToLongTimeString () As String

Restituisce

Stringa che contiene la rappresentazione di stringa dell'ora estesa dell'oggetto DateTime corrente.

Esempio

Nell'esempio seguente viene illustrato il ToLongTimeString metodo.

using System;
using System.Threading;
using System.Globalization;

public class Sample
{
   public static void Main()
   {
      // Create an array of culture names.
      String[] names = { "en-US", "en-GB", "fr-FR", "de-DE" };
      // Initialize a DateTime object.
      DateTime dateValue = new System.DateTime(2013, 5, 28, 10, 30, 15);

      // Iterate the array of culture names.
      foreach (var name in names) {
         // Change the culture of the current thread.
         Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(name);
         // Display the name of the current culture and the date.
         Console.WriteLine("Current culture: {0}", CultureInfo.CurrentCulture.Name);
         Console.WriteLine("Date: {0:G}", dateValue);

         // Display the long time pattern and the long time.
         Console.WriteLine("Long time pattern: '{0}'",
                           DateTimeFormatInfo.CurrentInfo.LongTimePattern);
         Console.WriteLine("Long time with format string:     {0:T}", dateValue);
         Console.WriteLine("Long time with ToLongTimeString:  {0}\n",
                           dateValue.ToLongTimeString());

Commenti

Il valore dell'oggetto corrente DateTime viene formattato utilizzando il modello definito dalla DateTimeFormatInfo.LongTimePattern proprietà associata alle impostazioni cultura correnti. Il valore restituito è identico al valore restituito specificando la stringa di formato di data e ora standard "T" con il ToString(String) metodo .

Nota

La stringa restituita dal ToLongTimeString metodo è sensibile alle impostazioni cultura. Riflette il modello definito dalla proprietà delle DateTimeFormatInfo.LongTimePattern impostazioni cultura correnti. Ad esempio, per le impostazioni cultura en-US, il modello di tempo lungo standard è "h:mm:ss tt"; per le impostazioni cultura de-DE, è "HH:mm:ss"; per le impostazioni cultura ja-JP, è "H:mm:ss". Si noti che il relativo valore può variare a seconda dell'implementazione di .NET e della relativa versione, del sistema operativo e della relativa versione e della personalizzazione dell'utente.

Per altre informazioni sulle impostazioni cultura del thread corrente, vedere le proprietà CultureInfo.CurrentCulture e Thread.CurrentCulture. Per altre informazioni sui caratteri e i modelli di formato e sull'output che producono, vedere Stringhe di formato di data e ora standard e Stringhe di formato di data e ora personalizzato. Per altre informazioni sulla modifica del modello di formato associato a un carattere di formato, vedere la classe DateTimeFormatInfo.
