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)

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.


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.

No code example is currently available or this language may not be supported.
// A new 'HttpWebRequest' object is created.
HttpWebRequest* myHttpWebRequest =
myHttpWebRequest->SendChunked = true;
// 'TransferEncoding' property is set to 'gzip'.
myHttpWebRequest->TransferEncoding = S"gzip";
Console::WriteLine(S"\nPlease Enter the data to be posted to the (http://<machine name>/CodeSnippetTest::asp) uri:");
String* inputData = Console::ReadLine();
String* postData=String::Concat(S"testdata= ", inputData);
// 'Method' property of 'HttpWebRequest' class is set to POST.
myHttpWebRequest->Method = S"POST";
ASCIIEncoding* encodedData = new ASCIIEncoding();
Byte byteArray[] = encodedData->GetBytes(postData);
// 'ContentType' property of the 'HttpWebRequest' class is set to S"application/x-www-form-urlencoded".
myHttpWebRequest->ContentType = S"application/x-www-form-urlencoded";
// 'ContentLength' property is set to Length of the data to be posted.
myHttpWebRequest->ContentLength = byteArray->Length;
Stream* newStream = myHttpWebRequest->GetRequestStream();
newStream->Write(byteArray, 0, byteArray->Length);
Console::WriteLine(S"\nData has been posted to the Uri\n\nPlease wait for the response..........");
// The response object of 'HttpWebRequest' is assigned to a 'HttpWebResponse' variable.
HttpWebResponse* myHttpWebResponse =
// Displaying the contents of the page to the console
Stream* streamResponse = myHttpWebResponse->GetResponseStream();
StreamReader* streamRead = new StreamReader(streamResponse);
Char readBuff[] = new Char[256];
int count = streamRead->Read(readBuff, 0, 256);
Console::WriteLine(S"\nThe contents of the HTML page are :  ");
while (count > 0) {
   String* outputData = new String(readBuff, 0, count);
   count = streamRead->Read(readBuff, 0, 256);
// Release the response object resources.
