Contoh membuat instans DateTimeFormatInfo objek yang mewakili budaya invarian dengan memanggil DateTimeFormatInfo konstruktor. Ini juga dapat mengambil DateTimeFormatInfo yang mewakili budaya invarian dari InvariantInfo properti .

Keterangan

Metode ini mengembalikan array yang berisi semua string format kustom yang sesuai dengan string format standar. Lihat String Format Tanggal dan Waktu Standar untuk daftar string format standar.

Anda dapat menggunakan string format kustom dalam array yang dikembalikan oleh GetAllDateTimePatterns metode dalam operasi pemformatan. Namun, jika Anda melakukannya, representasi string dari nilai tanggal dan waktu yang dikembalikan dalam operasi pemformatan tersebut Parse tidak selalu dapat diurai dengan sukses oleh metode dan TryParse . Oleh karena itu, Anda tidak dapat berasumsi bahwa string format kustom yang dikembalikan oleh GetAllDateTimePatterns metode dapat digunakan untuk nilai tanggal dan waktu pulang pergi. Contoh berikut mengilustrasikan masalah ini. Ini mengambil DateTimeFormatInfo objek yang berisi informasi pemformatan untuk budaya Italia (Italia). Ini meneruskan setiap string format kustom dalam array yang dikembalikan oleh GetAllDateTimePatterns() metode ke DateTime.ToString(String) metode untuk membuat representasi string tanggal dan waktu. Contoh ini kemudian mencoba mengurai nilai ini dengan memanggil DateTime.TryParse(String, DateTime) metode . Seperti yang ditunjukkan oleh output dari contoh, beberapa string format kustom tidak menghasilkan nilai tanggal dan waktu yang berhasil pulang-pergi.

Keterangan

Metode ini mengembalikan array yang berisi string format kustom yang sesuai dengan string format standar tertentu. Lihat String Format Tanggal dan Waktu Standar untuk daftar string format standar.

Anda dapat menggunakan string format kustom dalam array yang dikembalikan oleh GetAllDateTimePatterns metode dalam operasi pemformatan. Namun, jika Anda melakukannya, representasi string dari nilai tanggal dan waktu yang dikembalikan dalam operasi pemformatan tersebut Parse tidak selalu dapat diurai dengan sukses oleh metode dan TryParse . Oleh karena itu, Anda tidak dapat berasumsi bahwa string format kustom yang dikembalikan oleh GetAllDateTimePatterns metode dapat digunakan untuk nilai tanggal dan waktu pulang pergi. Contoh berikut mengilustrasikan masalah ini. Ini mengambil DateTimeFormatInfo objek yang berisi informasi pemformatan untuk budaya Rusia (Rusia). Ini memanggil GetAllDateTimePatterns(Char) metode untuk setiap string format standar, lalu meneruskan setiap string format kustom dalam array yang dikembalikan ke DateTime.ToString(String) metode untuk membuat representasi string tanggal dan waktu. Contoh ini kemudian mencoba mengurai nilai ini dengan memanggil DateTime.TryParse(String, DateTime) metode . Seperti yang ditunjukkan oleh output dari contoh, beberapa string format kustom tidak menghasilkan nilai tanggal dan waktu yang berhasil pulang-pergi.
