HttpWebRequest.Pipelined-Eigenschaft

Ruft einen Wert ab, der angibt, ob die Anforderung über Pipelineverbindungen zur Internetressource gesendet werden soll, oder legt diesen fest.

Namespace: System.Net
Assembly: System (in system.dll)

Syntax

'Declaration
Public Property Pipelined As Boolean
'Usage
Dim instance As HttpWebRequest
Dim value As Boolean

value = instance.Pipelined

instance.Pipelined = value

public bool Pipelined { get; set; }

public:
property bool Pipelined {
    bool get ();
    void set (bool value);
}

/** @property */
public boolean get_Pipelined ()

/** @property */
public void set_Pipelined (boolean value)

public function get Pipelined () : boolean

public function set Pipelined (value : boolean)

Eigenschaftenwert

true, wenn die Anforderung über Pipelineverbindungen gesendet werden soll, andernfalls false. Der Standardwert ist true.

Hinweise

Eine Anwendung verwendet die Pipelined-Eigenschaft, um anzugeben, dass Pipelineverbindungen angemessen sind. Wenn die Pipelined-Eigenschaft true ist, stellt die Anwendung Pipelineverbindungen mit den Servern her, die dies unterstützen.

Pipelineverbindungen werden nur dann hergestellt, wenn auch die KeepAlive-Eigenschaft true ist.

Beispiel

Im folgenden Codebeispiel wird der Wert der Pipelined-Eigenschaft auf der Konsole ausgegeben.
