public:
property bool Pipelined { bool get(); void set(bool value); };
public bool Pipelined { get; set; }
member this.Pipelined : bool with get, set
Public Property Pipelined As Boolean
Nilai Properti
true
jika permintaan harus disalurkan; jika tidak, false
. Defaultnya adalah true
.
Contoh
Contoh kode berikut mencetak nilai properti Pipelined ke konsol.
// Create a 'HttpWebRequest' object.
HttpWebRequest^ myHttpWebRequest = (HttpWebRequest^)( WebRequest::Create( myUri ) );
// Assign the response object of 'HttpWebRequest' to a 'HttpWebResponse' variable.

Keterangan
Hati
WebRequest
, HttpWebRequest
, ServicePoint
, dan WebClient
usang, dan Anda tidak boleh menggunakannya untuk pengembangan baru. Gunakan HttpClient sebagai gantinya.
Aplikasi menggunakan properti Pipelined untuk menunjukkan preferensi koneksi yang disalurkan. Ketika Pipelinedtrue
, aplikasi membuat koneksi pipelin ke server yang mendukungnya.
Koneksi yang disalurkan hanya dibuat ketika properti KeepAlive juga true
.
