WebRequest::GetRequestStream Method

When overridden in a descendant class, returns a Stream for writing data to the Internet resource.

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

public:
virtual Stream^ GetRequestStream()

Return Value

Type: System.IO::Stream
A Stream for writing data to the Internet resource.

ExceptionCondition
NotImplementedException

Any attempt is made to access the method, when the method is not overridden in a descendant class.

The GetRequestStream method initiates a request to send data to the Internet resource and returns a Stream instance for sending data to the Internet resource.

The GetRequestStream method provides synchronous access to the Stream. For asynchronous access, use the BeginGetRequestStream and EndGetRequestStream methods.

NoteNote

The WebRequest class is an abstract class. The actual behavior of WebRequest instances at run time is determined by the descendant class returned by the WebRequest::Create method. For more information about default values and exceptions, see the documentation for the descendant classes, such as HttpWebRequest and FileWebRequest.

The following example uses the GetRequestStream method to obtain a stream and then writes data that stream.


// Set the 'ContentType' property of the WebRequest.
myWebRequest->ContentType = "application/x-www-form-urlencoded";

// Set the 'ContentLength' property of the WebRequest.
myWebRequest->ContentLength = byteArray->Length;
Stream^ newStream = myWebRequest->GetRequestStream();
newStream->Write( byteArray, 0, byteArray->Length );

// Close the Stream object.
newStream->Close();

// Assign the response object of 'WebRequest' to a 'WebResponse' variable.
WebResponse^ myWebResponse = myWebRequest->GetResponse();
