HttpWebRequest.SendChunked Özellik

Tanım

Ad Alanı:

System.Net

Bütünleştirilmiş Kod:

System.Net.Requests.dll

Kaynak:

HttpWebRequest.cs

Segmentlerdeki verilerin İnternet kaynağına gönderilip gönderilmeydiğini gösteren bir değer alır veya ayarlar.

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

public bool SendChunked { get; set; }

member this.SendChunked : bool with get, set

Public Property SendChunked As Boolean

Özellik Değeri

Boolean

İnternet kaynağına segmentler halinde veri göndermek için true; aksi takdirde false. Varsayılan değer false.

Özel durumlar

InvalidOperationException

İstek, GetRequestStream(), BeginGetRequestStream(AsyncCallback, Object), GetResponse()veya BeginGetResponse(AsyncCallback, Object) yöntemi çağrılarak başlatılmıştır.

Örnekler

Aşağıdaki kod örneği SendChunked özelliğini true olarak ayarlayarak verilerin İnternet kaynağına segmentler halinde gönderilmesini sağlar.

Açıklamalar

Dikkat

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

SendChunked trueolduğunda, istek İnternet kaynağına segmentler halinde veri gönderir. İnternet kaynağı öbeklenmiş verilerin alınmasını desteklemelidir.

İstek başlatıldıktan sonra GetRequestStream, BeginGetRequestStream, GetResponseveya BeginGetResponse yöntemini çağırarak SendChunked özelliğini değiştirmek bir InvalidOperationExceptionoluşturur.
