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

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. WebRequest^ myWebRequest = WebRequest::Create( "http://www.contoso.com" ); // Send the 'WebRequest' and wait for response. WebResponse^ myWebResponse = myWebRequest->GetResponse(); // Obtain a 'Stream' object associated with the response object. Stream^ ReceiveStream = myWebResponse->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( "\nResponse stream received" ); array<Char>^ read = gcnew array<Char>(256); // Read 256 charcters at a time. int count = readStream->Read( read, 0, 256 ); Console::WriteLine( "HTML...\r\n" ); while ( count > 0 ) { // Dump the 256 characters on a string and display the string onto the console. String^ str = gcnew String( read,0,count ); Console::Write( str ); count = readStream->Read( read, 0, 256 ); } Console::WriteLine( "" ); // Release the resources of stream object. readStream->Close(); // Release the resources of response object. myWebResponse->Close();
