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.

// Display the contents of the page to the console.

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.
