Assembly:  System (in System.dll)

Public Overridable Function GetResponseStream As Stream

Return Value

Type: System.IO.Stream

An instance of the Stream class for reading data from the Internet resource.

Exception Condition
NotSupportedException

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

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

System_CAPS_noteNote

The response stream must be closed to avoid running out of system resources. The response stream can be closed by calling Stream.Close or Close

The following example uses GetResponseStream to return a StreamReader instance. A small local buffer is used to read data from the StreamReader and output it to the console.


  ' Create a 'WebRequest' object with the specified url 
  Dim myWebRequest As WebRequest = WebRequest.Create("www.contoso.com")

  ' Send the 'WebRequest' and wait for response.
  Dim myWebResponse As WebResponse = myWebRequest.GetResponse()

  ' Call method 'GetResponseStream' to obtain stream associated with the response object
  Dim ReceiveStream As Stream = myWebResponse.GetResponseStream()

  Dim encode As Encoding = System.Text.Encoding.GetEncoding("utf-8")

  ' Pipe the stream to a higher level stream reader with the required encoding format.
  Dim readStream As New StreamReader(ReceiveStream, encode)
  Console.WriteLine(ControlChars.Cr + "Response stream received")
  Dim read(256) As [Char]

  ' Read 256 charcters at a time    .
  Dim count As Integer = readStream.Read(read, 0, 256)
  Console.WriteLine("HTML..." + ControlChars.Lf + ControlChars.Cr)
  While count > 0

      ' Dump the 256 characters on a string and display the string onto the console.
      Dim str As New [String](read, 0, count)
      Console.Write(str)
      count = readStream.Read(read, 0, 256)

  End While
  Console.WriteLine("")

  ' Release the resources of stream object.
readStream.Close()

' Release the resources of response object.
  myWebResponse.Close()
