En el ejemplo siguiente se usa el método GetResponseStream para devolver el flujo de datos del recurso del sistema de archivos.The following example uses the GetResponseStream method to return the data stream from the file system resource.

Uri^ fileUrl = gcnew Uri( String::Concat( "file://", url ) );
// Create a 'FileWebrequest' Object* with the specified Uri.
FileWebRequest^ myFileWebRequest = (FileWebRequest^)( WebRequest::Create( fileUrl ) );
// Send the 'FileWebRequest' Object* and wait for response.
FileWebResponse^ myFileWebResponse = (FileWebResponse^)( myFileWebRequest->GetResponse() );

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

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

array<Char>^ read = gcnew array<Char>(256);
// Read 256 characters at a time.
