Açıklamalar

Geçerli nesnenin değeri, geçerli DateTime kültürle ilişkilendirilmiş özellik tarafından LongDatePattern tanımlanan desen kullanılarak biçimlendirilir. Dönüş değeri, yöntemiyle "D" standart DateTime biçim dizesini belirterek döndürülen değerle aynıdır ToString(String) .

Geçerli iş parçacığı kültürü hakkında daha fazla bilgi için ve Thread.CurrentCulture özelliklerine CultureInfo.CurrentCulture bakın. Biçim karakterleri, biçim desenleri ve ürettikleri çıkış hakkında daha fazla bilgi için bkz. Standart tarih ve saat biçim dizeleri ve Özel tarih ve saat biçim dizeleri. Biçim karakteriyle ilişkili biçim desenini değiştirme hakkında daha fazla bilgi için sınıfına DateTimeFormatInfo bakın.
