Commenti

Il valore dell'oggetto corrente DateTime viene formattato utilizzando il criterio definito DateTimeFormatInfo.LongTimePattern dalla proprietà associata alle impostazioni cultura del thread corrente.The value of the current DateTime object is formatted using the pattern defined by the DateTimeFormatInfo.LongTimePattern property associated with the current thread culture. Il valore restituito è identico al valore restituito specificando la stringa di formato di data e ora standard "T" ToString(String) con il metodo.The return value is identical to the value returned by specifying the "T" standard date and time format string with the ToString(String) method.

Nota

La stringa restituita dal ToLongTimeString metodo è dipendente dalle impostazioni cultura.The string returned by the ToLongTimeString method is culture-sensitive. Riflette il modello definito dalla DateTimeFormatInfo.LongTimePattern proprietà delle impostazioni cultura correnti.It reflects the pattern defined by the current culture's DateTimeFormatInfo.LongTimePattern property. Per le impostazioni cultura en-US, ad esempio, il modello di ora estesa 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".For example, for the en-US culture, the standard long time pattern is "h:mm:ss tt"; for the de-DE culture, it is "HH:mm:ss"; for the ja-JP culture, it is "H:mm:ss". Si noti che il valore può variare a seconda dell'implementazione di .NET e della relativa versione, del sistema operativo e della relativa versione, nonché della personalizzazione dell'utente.Note that its value can vary depending on the .NET implementation and its version, the operating system and its version, and user customization.

Per altre informazioni sulle impostazioni cultura del thread corrente, vedere le proprietà CultureInfo.CurrentCulture e Thread.CurrentCulture.For more information about the current thread culture, see the CultureInfo.CurrentCulture and Thread.CurrentCulture properties. 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.For more information about format characters, format patterns, and the output they produce, see Standard date and time format strings and Custom date and time format strings. Per altre informazioni sulla modifica del modello di formato associato a un carattere di formato, vedere la classe DateTimeFormatInfo.For more information about changing the format pattern associated with a format character, see the DateTimeFormatInfo class.
