HttpWebRequest..::.SendChunked Property

Gets or sets a value that indicates whether to send data in segments to the Internet resource.

Namespace:  System.Net
Assembly:  System (in System.dll)
Visual Basic (Declaration)
Public Property SendChunked As Boolean
Visual Basic (Usage)
Dim instance As HttpWebRequest
Dim value As Boolean

value = instance.SendChunked

instance.SendChunked = value
C#
public bool SendChunked { get; set; }
Visual C++
public:
property bool SendChunked {
    bool get ();
    void set (bool value);
}
JScript
public function get SendChunked () : boolean
public function set SendChunked (value : boolean)

Property Value

Type: System..::.Boolean
true to send data to the Internet resource in segments; otherwise, false. The default value is false.
ExceptionCondition
InvalidOperationException

The request has been started by calling the GetRequestStream, BeginGetRequestStream, GetResponse, or BeginGetResponse method.

When SendChunked is true, the request sends data to the Internet resource in segments. The Internet resource must support receiving chunked data.

Changing the SendChunked property after the request has been started by calling the GetRequestStream, BeginGetRequestStream, GetResponse, or BeginGetResponse method throws an InvalidOperationException.

The following code example sets the SendChunked property to true so that data can be sent in segments to the Internet resource.
