FileWebResponse.GetResponseStream Method

Returns the data stream from the file system resource.

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

'Declaration
Public Overrides Function GetResponseStream As Stream
'Usage
Dim instance As FileWebResponse 
Dim returnValue As Stream 

returnValue = instance.GetResponseStream()

Return Value

Type: System.IO.Stream
A Stream for reading data from the file system resource.

The GetResponseStream method returns the data stream from the file system resource.

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 the GetResponseStream method to return the data stream from the file system resource.

Dim fileUrl As New Uri("file://" + url)
' Create a 'FileWebrequest' object with the specified Uri . 
Dim myFileWebRequest As FileWebRequest = CType(WebRequest.Create(fileUrl), FileWebRequest)
' Send the 'fileWebRequest' and wait for response.  
Dim myFileWebResponse As FileWebResponse = CType(myFileWebRequest.GetResponse(), FileWebResponse)


' CALLING METHOD GetResponseStream will return the stream associated with the response object. 
Dim ReceiveStream As Stream = myFileWebResponse.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.Lf + ControlChars.Cr + "Response stream received")

Dim read(256) As [Char]
' Reading 256 characters at a time.     
Dim count As Integer = readStream.Read(read, 0, 256)
Console.WriteLine("File Data..." + 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.
myFileWebResponse.Close()
Uri* fileUrl = new Uri(String::Concat(S"file://", url));
// Create a 'FileWebrequest' Object* with the specified Uri.
FileWebRequest* myFileWebRequest = dynamic_cast<FileWebRequest*>(WebRequest::Create(fileUrl));
// Send the 'FileWebRequest' Object* and wait for response.
FileWebResponse* myFileWebResponse = dynamic_cast<FileWebResponse*>(myFileWebRequest->GetResponse());

// Get the stream Object* associated with the response Object*.
Stream*  receiveStream = myFileWebResponse->GetResponseStream();

Encoding*  encode = System::Text::Encoding::GetEncoding(S"utf-8");
// Pipe the stream to a higher level stream reader with the required encoding format.
StreamReader* readStream = new StreamReader(receiveStream, encode);
Console::WriteLine(S"\r\nResponse stream received");

Char read[] = new Char[256];
// Read 256 characters at a time.
int count = readStream->Read(read, 0, 256);
Console::WriteLine(S"File Data...\r\n");
while (count > 0) {
   // Dump the 256 characters on a String* and display the String* onto the console.
   String* str = new String(read, 0, count);
   Console::Write(str);
   count = readStream->Read(read, 0, 256);
}
Console::WriteLine(S"");
// Release resources of stream Object*.
readStream->Close();
// Release resources of response Object*.
myFileWebResponse->Close();
