.NET Framework Class Library
HttpWebResponse..::.GetResponseStream Method

Gets the stream that is used to read the body of the response from the server.

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

Visual Basic (Declaration)
Public Overrides Function GetResponseStream As Stream
Visual Basic (Usage)
Dim instance As HttpWebResponse
Dim returnValue As Stream

returnValue = instance.GetResponseStream()
C#
public override Stream GetResponseStream()
Visual C++
public:
virtual Stream^ GetResponseStream() override
JScript
public override function GetResponseStream() : Stream

Return Value

Type: System.IO..::.Stream
A Stream containing the body of the response.
Exceptions

ExceptionCondition
ProtocolViolationException

There is no response stream.

ObjectDisposedException

The current instance has been disposed.

Remarks

The GetResponseStream method returns the data stream from the requested Internet resource.

NoteNote:

You must call either the Stream..::.Close or the HttpWebResponse..::.Close method to close the stream and release the connection for reuse. It is not necessary to call both Stream..::.Close and HttpWebResponse..::.Close, but doing so does not cause an error. Failure to close the stream will cause your application to run out of connections.

NoteNote:

This member outputs trace information when you enable network tracing in your application. For more information, see Network Tracing.

Examples

The following example demonstrates how to use GetResponseStream to return the Stream instance used to read the response from the server.

Visual Basic
            ' Creates an HttpWebRequest for the specified URL. 
            Dim myHttpWebRequest As HttpWebRequest = CType(WebRequest.Create(url), HttpWebRequest)

            Dim myHttpWebResponse As HttpWebResponse = CType(myHttpWebRequest.GetResponse(), HttpWebResponse)
            ' Calls the method GetResponseStream to return the stream associated with the response.
            Dim receiveStream As Stream = myHttpWebResponse.GetResponseStream()
            Dim encode As Encoding = System.Text.Encoding.GetEncoding("utf-8")
            ' Pipes the response stream to a higher level stream reader with the required encoding format. 
            Dim readStream As New StreamReader(receiveStream, encode)
            Console.WriteLine(ControlChars.Lf + ControlChars.Cr + "Response stream received")
            Dim read(256) As [Char]
            ' Reads 256 characters at a time.    
            Dim count As Integer = readStream.Read(read, 0, 256)
