HttpWebRequest.Pipelined プロパティ

定義

インターネット リソースに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。

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

プロパティ値

要求をパイプライン化する必要があるかどうかを true します。それ以外の場合は、falseします。 既定値は trueです。

次のコード例では、Pipelined プロパティの値をコンソールに出力します。

注意

WebRequestHttpWebRequestServicePointWebClient は廃止されており、新しい開発には使用しないでください。 代わりに HttpClient を使用してください。

アプリケーションは、Pipelined プロパティを使用して、パイプライン接続の優先設定を示します。 Pipelinedtrueされると、アプリケーションはそれらをサポートするサーバーにパイプライン接続を行います。

パイプライン接続は、KeepAlive プロパティも true場合にのみ行われます。
