Tanım

Ad Alanı:

System.Net

Bütünleştirilmiş Kod:

System.Net.Requests.dll

Kaynak:

HttpWebRequest.cs

İsteğin İnternet kaynağına işlem hattı oluşturup oluşturmayacağını belirten bir değer alır veya ayarlar.

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

Özellik Değeri

Boolean

İsteğin işlem hattı oluşturularak gerçekleştirilip gerçekleştirilmediğini true; aksi takdirde false. Varsayılan değer true.

Açıklamalar

Dikkat

WebRequest, HttpWebRequest, ServicePointve WebClient kullanım dışıdır ve bunları yeni geliştirme için kullanmamalısınız. Bunun yerine HttpClient kullanın.

Bir uygulama, işlem hattı bağlantıları için bir tercih belirtmek için Pipelined özelliğini kullanır. Pipelined trueolduğunda, bir uygulama bunları destekleyen sunuculara işlem hattıyla bağlantı kurar.

İşlem hattı bağlantıları yalnızca KeepAlive özelliği de trueolduğunda yapılır.
