HttpWebRequest.SendChunked-Eigenschaft

  • Artikel

Ruft einen Wert ab, der angibt, ob die Daten in Segmenten an die Internetressource gesendet werden sollen, oder legt diesen fest.

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

Syntax

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

value = instance.SendChunked

instance.SendChunked = value

public bool SendChunked { get; set; }

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

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

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

public function get SendChunked () : boolean

public function set SendChunked (value : boolean)

Eigenschaftenwert

true, um die Daten in Segmenten an die Internetressource zu senden, andernfalls false. Der Standardwert ist false.

Ausnahmen

Ausnahmetyp Bedingung

InvalidOperationException

Die Anforderung wurde durch Aufrufen der GetRequestStream-Methode, der BeginGetRequestStream-Methode, der GetResponse-Methode oder der BeginGetResponse-Methode gestartet.

Hinweise

Wenn SendChunked auf true festgelegt ist, sendet die Anforderung Daten in Segmenten an die Internetressource. Die Internetressource muss das Empfangen von Daten in Segmenten unterstützen.

Wenn die SendChunked-Eigenschaft geändert wird, nachdem die Anforderung durch den Aufruf der GetRequestStream-Methode, der BeginGetRequestStream-Methode, der GetResponse-Methode oder der BeginGetResponse-Methode gestartet wurde, wird eine InvalidOperationException ausgelöst.

Beispiel

Im folgenden Codebeispiel wird die SendChunked-Eigenschaft auf true festgelegt, sodass Daten in Segmenten an die Internetressource gesendet werden können.
