for value in strings do

Keterangan

Metode ini dibandingkan dengan substring di akhir instans value ini yang panjangnya sama dengan value, dan mengembalikan indikasi apakah keduanya sama. Agar sama, value harus menjadi referensi ke instans yang sama ini atau cocok dengan akhir instans ini.

Metode ini melakukan perbandingan kata (peka huruf besar/kecil dan budaya) menggunakan budaya saat ini.

Catatan Bagi Pemanggil

Seperti yang dijelaskan dalam Praktik Terbaik untuk Menggunakan String, kami sarankan Anda menghindari memanggil metode perbandingan string yang menggantikan nilai default dan sebaliknya memanggil metode yang mengharuskan parameter ditentukan secara eksplisit. Untuk menentukan apakah string diakhiri dengan substring tertentu dengan menggunakan aturan perbandingan CurrentCulture string dari budaya saat ini, beri sinyal niat Anda secara eksplisit dengan memanggil EndsWith(String, StringComparison) metode kelebihan beban dengan nilai untuk parameternyacomparisonType. Jika Anda tidak memerlukan perbandingan sadar linguistik, pertimbangkan untuk menggunakan Ordinal.

Keterangan

Metode EndsWith membandingkan value parameter dengan substring di akhir string ini dan mengembalikan nilai yang menunjukkan apakah keduanya sama. Agar sama, value harus berupa referensi ke string yang sama ini, harus berupa string kosong (""), atau harus cocok dengan akhir string ini. Jenis perbandingan yang EndsWith dilakukan oleh metode tergantung pada nilai comparisonType parameter.

Parameter

value
String

String untuk dibandingkan dengan substring di akhir instans ini.

ignoreCase
Boolean

true untuk mengabaikan kasus selama perbandingan; jika tidak, false.

culture
CultureInfo

Informasi budaya yang menentukan bagaimana instans ini dan value dibandingkan. Jika culture adalah null, budaya saat ini digunakan.

Mengembalikan

Boolean

truevalue jika parameter cocok dengan akhir string ini; jika tidak, false.

Pengecualian

ArgumentNullException

valueadalah null.

Keterangan

Metode ini membandingkan value parameter dengan substring di akhir string ini yang panjangnya sama dengan value, dan mengembalikan nilai yang menunjukkan apakah keduanya sama. Agar sama, value harus menjadi referensi ke instans yang sama ini atau cocok dengan akhir string ini.

Metode ini melakukan perbandingan kata (peka budaya) menggunakan casing dan budaya yang ditentukan.
