Contoh

Contoh kode berikut membuat objek ServicePoint yang tersambung ke URI www.contoso.com.

// This example shows how to use the ServicePoint and ServicePointManager classes.
// The ServicePointManager class uses the ServicePoint class to manage connections
// to a remote host. The networking classes reuse service points for all 
// requests to a given URI. In fact, the same ServicePoint object 
// is used to issue requests to Internet resources identified by the same
// scheme identifier (for example,  HTTP) and host fragment (for example,  www.contoso.com).  
// This should improve your application performance. 
// Reusing service points in this way can help improve application performance.

Keterangan

Hati

WebRequest, HttpWebRequest, ServicePoint, dan WebClient usang, dan Anda tidak boleh menggunakannya untuk pengembangan baru. Gunakan HttpClient sebagai gantinya.

Kelas ServicePoint menangani koneksi ke sumber daya Internet berdasarkan informasi host yang diteruskan di Pengidentifikasi Sumber Daya Seragam (URI) sumber daya sumber daya. Koneksi awal ke sumber daya menentukan informasi yang dipertahankan objek ServicePoint, yang kemudian dibagikan oleh semua permintaan berikutnya ke sumber daya tersebut.

ServicePoint objek dikelola oleh kelas ServicePointManager dan dibuat, jika perlu, dengan metode ServicePointManager.FindServicePoint. ServicePoint objek tidak pernah dibuat secara langsung tetapi selalu dibuat dan dikelola oleh kelas ServicePointManager. Jumlah maksimum objek ServicePoint yang dapat dibuat diatur oleh properti ServicePointManager.MaxServicePoints.

Setiap objek ServicePoint mempertahankan koneksinya ke sumber daya Internet hingga diam lebih lama dari waktu yang ditentukan dalam properti MaxIdleTime. Ketika ServicePoint melebihi nilai MaxIdleTime, ServicePoint dapat didaur ulang ke koneksi lain. Nilai default MaxIdleTime diatur oleh properti ServicePointManager.MaxServicePointIdleTime.

Ketika properti ConnectionLeaseTimeout diatur ke nilai selain -1, dan setelah waktu yang ditentukan berlalu, koneksi ServicePoint aktif ditutup setelah melayani permintaan berikutnya. Ini berguna untuk aplikasi yang tidak memerlukan koneksi aktif yang dibuka tanpa batas waktu, karena secara default.

Nota

Dalam kondisi beban tinggi, beberapa aplikasi mungkin kehabisan utas gratis di ThreadPool, yang dapat menyebabkan performa sistem yang buruk (seperti waktu transaksi tinggi dan variabel).
