Keterangan

Secara default, perbandingan dilakukan dengan menggunakan CompareOptions.None. Jika keputusan keamanan bergantung pada perbandingan string atau perubahan kasus, Anda harus menggunakan InvariantCulture properti untuk memastikan bahwa perilaku konsisten terlepas dari pengaturan budaya sistem operasi.

Catatan

Jika memungkinkan, Anda harus memanggil metode perbandingan string yang memiliki parameter jenis CompareOptions untuk menentukan jenis perbandingan yang diharapkan. Sebagai aturan umum, gunakan opsi linguistik (menggunakan budaya saat ini) untuk membandingkan string yang ditampilkan di antarmuka pengguna dan tentukan Ordinal atau OrdinalIgnoreCase untuk perbandingan keamanan.

Catatan Bagi Pemanggil

Set karakter termasuk karakter yang dapat diabaikan, yang merupakan karakter yang tidak dipertimbangkan saat melakukan perbandingan linguistik atau sensitif terhadap budaya. Metode ini Compare(String, String) tidak mempertimbangkan karakter tersebut ketika melakukan perbandingan yang sensitif terhadap budaya. Misalnya, perbandingan "hewan" yang sensitif terhadap budaya dengan "ani-mal" (menggunakan tanda hubung lunak, atau U+00AD) menunjukkan bahwa kedua string tersebut setara, seperti yang ditunjukkan contoh berikut.

Imports System.Globalization

Module Example
   Public Sub Main()
      Dim ci As CompareInfo = CultureInfo.CurrentCulture.CompareInfo
      Dim s1 As String = "ani" + ChrW(&h00AD) + "mal"
      Dim s2 As String = "animal"
      
      Console.WriteLine("Comparison of '{0}' and '{1}': {2}", 
                        s1, s2, ci.Compare(s1, s2))
  End Sub
End Module
' The example displays the following output:
'       Comparison of 'ani-mal' and 'animal': 0

Untuk mengenali karakter yang dapat diabaikan dalam perbandingan string, panggil Compare(String, String, CompareOptions) metode dan berikan nilai baik Ordinal atau OrdinalIgnoreCase untuk options parameter .

Keterangan

Jika keputusan keamanan bergantung pada perbandingan string atau perubahan kasus, Anda harus menggunakan InvariantCulture properti untuk memastikan bahwa perilaku tersebut konsisten terlepas dari pengaturan budaya sistem operasi.

Catatan

Jika memungkinkan, Anda harus memanggil metode perbandingan string yang memiliki parameter jenis CompareOptions untuk menentukan jenis perbandingan yang diharapkan. Sebagai aturan umum, gunakan opsi linguistik (menggunakan budaya saat ini) untuk membandingkan string yang ditampilkan di antarmuka pengguna dan menentukan Ordinal atau OrdinalIgnoreCase untuk perbandingan keamanan.

Catatan Bagi Pemanggil

Set karakter mencakup karakter yang tidak dapat diabaikan, yang merupakan karakter yang tidak dipertimbangkan saat melakukan perbandingan linguistik atau sensitif terhadap budaya. Metode ini Compare(String, Int32, String, Int32, CompareOptions) tidak mempertimbangkan karakter tersebut saat melakukan perbandingan yang sensitif terhadap budaya. Untuk mengenali karakter yang tidak dapat diabaikan dalam perbandingan Ordinal Anda, berikan nilai atau OrdinalIgnoreCase untuk options parameter .

Keterangan

Catatan

Jika memungkinkan, Anda harus menggunakan metode perbandingan string yang memiliki parameter jenis CompareOptions untuk menentukan jenis perbandingan yang diharapkan. Sebagai aturan umum, gunakan opsi linguistik (menggunakan budaya saat ini) untuk membandingkan string yang ditampilkan di antarmuka pengguna dan menentukan Ordinal atau OrdinalIgnoreCase untuk perbandingan keamanan.

Catatan Bagi Pemanggil

Kumpulan karakter mencakup karakter yang tidak dapat diabaikan. Metode ini Compare(String, Int32, Int32, String, Int32, Int32) tidak mempertimbangkan karakter ini ketika melakukan perbandingan linguistik atau sensitif budaya. Untuk mengenali karakter yang tidak dapat diabaikan dalam perbandingan Anda, panggil Compare(String, Int32, Int32, String, Int32, Int32, CompareOptions) metode dan berikan nilai Ordinal atau OrdinalIgnoreCase untuk options parameter .
