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

jika permintaan harus disalurkan; jika tidak, false
. Default adalah true
.
Contoh
Contoh kode berikut mencetak nilai Pipelined properti ke konsol.
// Create a 'HttpWebRequest' object.
HttpWebRequest^ myHttpWebRequest = (HttpWebRequest^)( WebRequest::Create( myUri ) );
// Assign the response object of 'HttpWebRequest' to a 'HttpWebResponse' variable.
HttpWebResponse^ myHttpWebResponse = (HttpWebResponse^)( myHttpWebRequest->GetResponse() );
// Display the contents of the page to the console.
Stream^ streamResponse = myHttpWebResponse->GetResponseStream();
StreamReader^ streamRead = gcnew StreamReader( streamResponse );
array<Char>^ readBuffer = gcnew array<Char>(256);
int count = streamRead->Read( readBuffer, 0, 256 );
Console::WriteLine( "\nThe contents of HTML page are......." );
while ( count > 0 )

Keterangan
Aplikasi menggunakan Pipelined properti untuk menunjukkan preferensi koneksi yang disalurkan. Kapan Pipelined adalah true
, aplikasi membuat koneksi yang disalurkan ke server yang mendukungnya.
Koneksi yang disalurkan hanya dibuat ketika KeepAlive properti juga true
.
