HttpWebRequest.Pipelined プロパティ

.NET Framework クラス ライブラリ リファレンス

HttpWebRequest.Pipelined プロパティ

インターネット リソースへの要求をパイプライン処理するかどうかを示す値を取得または設定します。

名前空間: System.Net
アセンブリ: System (system.dll 内)
構文

Visual Basic (宣言)

Public Property Pipelined As
 Boolean

Visual Basic (使用法)

Dim instance As HttpWebRequest
Dim value As Boolean

value = instance.Pipelined

instance.Pipelined = value

C#

public bool Pipelined { get;
 set; }

C++

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

J#

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

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

JScript

public function get Pipelined
 () : boolean

public function set Pipelined
 (value : boolean)

プロパティ値
要求をパイプライン処理する場合は true。それ以外の場合は false。既定値は true です。

解説

アプリケーションは Pipelined プロパティを使用して、パイプライン経由の接続に関する設定を示します。Pipelined が true の場合、アプリケーションは、それらをサポートするサーバーへのパイプライン接続を行います。

さらに KeepAlive プロパティが true の場合に限り、パイプライン接続を行います。

使用例

Pipelined プロパティの値をコンソールに出力するコード例を次に示します。
