Keterangan

Nilai objek saat ini DateTime diformat menggunakan penentu format tanggal dan waktu umum ('G'), yang memformat output menggunakan pola tanggal pendek dan pola waktu yang lama.

Format pola tanggal pendek dan waktu panjang ditentukan oleh provider parameter . Parameter provider dapat berupa salah satu hal berikut:

Jika provider adalah null, objek yang DateTimeFormatInfo terkait dengan budaya saat ini digunakan. Untuk informasi selengkapnya, lihat CultureInfo.CurrentCulture.

Catatan Bagi Pemanggil

Metode mengembalikan ToString(IFormatProvider) representasi string tanggal dan waktu dalam kalender yang digunakan oleh budaya yang provider diwakili oleh parameter . Kalendernya ditentukan oleh Calendar properti . Jika nilai instans saat ini DateTime lebih awal dari MinSupportedDateTime atau lebih baru dari MaxSupportedDateTime, metode akan melempar ArgumentOutOfRangeException. Contoh berikut memberikan ilustrasi. Ini mencoba memformat tanggal yang berada di luar rentang JapaneseCalendar kelas.

   public static void Main()
   {
      CultureInfo jaJP = new CultureInfo("ja-JP");

      DateTime date1 = new DateTime(1867, 1, 1);

      try {
         Console.WriteLine(date1.ToString(jaJP));
      }

DateTime.cs

Mengonversi nilai objek saat ini DateTime ke representasi string yang setara menggunakan format yang ditentukan dan konvensi pemformatan budaya saat ini.

public:
 System::String ^ ToString(System::String ^ format);
public string ToString (string format);
public string ToString (string? format);
override this.ToString : string -> string
Public Function ToString (format As String) As String

Parameter

format
String

String format tanggal dan waktu standar atau kustom.

Mengembalikan

Representasi string nilai objek saat ini DateTime seperti yang ditentukan oleh format.

Pengecualian

Panjangnya format adalah 1, dan bukan salah satu karakter penentu format yang ditentukan untuk DateTimeFormatInfo.

-atau-

format tidak berisi pola format kustom yang valid.

Tanggal dan waktu berada di luar rentang tanggal yang didukung oleh kalender yang digunakan oleh budaya saat ini.

Contoh

Contoh berikut menggunakan masing-masing string format tanggal dan waktu standar dan pilihan string format tanggal dan waktu kustom untuk menampilkan representasi DateTime string nilai. Budaya utas saat ini misalnya adalah en-US.

Keterangan

Metode mengembalikan ToString(String) representasi string dari nilai tanggal dan waktu dalam format tertentu yang menggunakan konvensi pemformatan budaya saat ini; untuk informasi selengkapnya, lihat CultureInfo.CurrentCulture.

Parameter format harus berisi karakter penentu format tunggal (lihat String Format Tanggal dan Waktu Standar) atau pola format kustom (lihat String Format Tanggal dan Waktu Kustom) yang menentukan format string yang dikembalikan. Jika format adalah null atau string kosong, penentu format umum, 'G', digunakan.

Beberapa kegunaan metode ini meliputi:

  • Mendapatkan string yang menampilkan tanggal dan waktu dalam format tanggal dan waktu singkat budaya saat ini. Untuk melakukan ini, Anda menggunakan penentu format "G".

  • Mendapatkan string yang hanya berisi bulan dan tahun. Untuk melakukan ini, Anda menggunakan string format "MM/yyyy". String format menggunakan pemisah tanggal budaya saat ini.

  • Mendapatkan string yang berisi tanggal dan waktu dalam format tertentu. Misalnya, string format "MM/dd/yyyyHH:mm" menampilkan string tanggal dan waktu dalam format tetap seperti "19//03//2013 18:06". String format menggunakan "/" sebagai pemisah tanggal tetap terlepas dari pengaturan khusus budaya.

  • Mendapatkan tanggal dalam format ringkas yang dapat digunakan untuk menserialisasikan string tanggal. Misalnya, string format "yyyyMMdd" menampilkan tahun empat digit diikuti oleh bulan dua digit dan hari dua digit tanpa pemisah tanggal.

Contoh berikut menggunakan ketiga string format ini untuk menampilkan nilai tanggal dan waktu dengan menggunakan konvensi budaya en-US dan fr-FR.

Mengembalikan

Representasi string dari nilai objek saat ini DateTime .

Pengecualian

Tanggal dan waktu berada di luar rentang tanggal yang didukung oleh kalender yang digunakan oleh budaya saat ini.

Contoh

Contoh berikut menggambarkan bagaimana representasi string dari nilai yang DateTime dikembalikan oleh ToString() metode tergantung pada budaya utas saat ini. Ini mengubah budaya saat ini menjadi en-US, fr-FR, dan ja-JP, dan dalam setiap kasus memanggil ToString() metode untuk mengembalikan representasi string dari nilai tanggal dan waktu menggunakan budaya tersebut.

Keterangan

Nilai objek saat ini DateTime diformat menggunakan penentu format tanggal dan waktu umum ('G'). Untuk memformatnya menggunakan penentu format tanggal dan waktu tertentu, panggil ToString(String) metode . Untuk memformatnya menggunakan penentu format tanggal dan waktu umum ('G') untuk budaya tertentu, panggil ToString(IFormatProvider) metode . Untuk memformatnya menggunakan penentu format tanggal dan waktu tertentu dan konvensi budaya tertentu, panggil ToString(String, IFormatProvider) metode .

Metode ini menggunakan informasi pemformatan yang berasal dari budaya saat ini. Secara khusus, ini menggabungkan string format kustom yang dikembalikan oleh ShortDatePattern properti dan LongTimePattern objek yang DateTimeFormatInfo dikembalikan oleh Thread.CurrentThread.CurrentCulture.DateTimeFormat properti . Untuk informasi selengkapnya, lihat CultureInfo.CurrentCulture. Kelebihan beban ToString metode lainnya memungkinkan Anda menentukan budaya yang pemformatannya digunakan dan untuk menentukan pola DateTime output nilai.

Catatan Bagi Pemanggil

Metode mengembalikan ToString() representasi string tanggal dan waktu dalam kalender yang digunakan oleh budaya saat ini. Jika nilai instans saat ini DateTime lebih awal dari MinSupportedDateTime atau lebih baru dari MaxSupportedDateTime, metode akan melempar ArgumentOutOfRangeException.

Contoh berikut menunjukkan berbagai cara memformat DateTime nilai menggunakan invariant DateTimeFormatInfo.

using namespace System;
using namespace System::Globalization;
void main()
{
   DateTime dt = DateTime::Now;
   array<String^>^format = {L"d",L"D",L"f",L"F",L"g",L"G",L"m",L"r",L"s",L"t",L"T",L"u",L"U",L"y",L"dddd, MMMM dd yyyy",L"ddd, MMM d \"'\"yy",L"dddd, MMMM dd",L"M/yy",L"dd-MM-yy"};
   String^ date;
   for ( int i = 0; i < format->Length; i++ )
   {
      date = dt.ToString( format[ i ], DateTimeFormatInfo::InvariantInfo );
      Console::WriteLine( String::Concat( format[ i ], L" :", date ) );

   }

Keterangan

Parameter format dapat berisi karakter penentu format tunggal (lihat String Format Tanggal dan Waktu Standar) atau pola format kustom (lihat String Format Tanggal dan Waktu Kustom). Jika format adalah null atau string kosong (""), penentu format standar, "G", digunakan.

Parameter provider menentukan pola yang sesuai dengan penentu format standar, serta simbol dan nama komponen tanggal dan waktu. Parameter provider dapat berupa salah satu hal berikut:

Jika provider adalah null, yang DateTimeFormatInfo terkait dengan budaya saat ini digunakan. Untuk informasi selengkapnya, lihat CultureInfo.CurrentCulture.

Catatan Bagi Pemanggil

Metode mengembalikan ToString(String, IFormatProvider) representasi string tanggal dan waktu dalam kalender yang provider digunakan oleh parameter . Kalendernya ditentukan oleh Calendar properti . Jika nilai instans saat ini DateTime lebih awal dari MinSupportedDateTime atau lebih baru dari MaxSupportedDateTime, metode akan melempar ArgumentOutOfRangeException. Contoh berikut memberikan ilustrasi. Ini mencoba memformat tanggal yang berada di luar rentang UmAlQuraCalendar kelas.
