Examples

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

C#

// Creates an HttpWebRequest with the specified URL.
    HttpWebRequest myHttpWebRequest = (HttpWebRequest)WebRequest.Create(url);
    // Sends the HttpWebRequest and waits for the response.			
    HttpWebResponse myHttpWebResponse = (HttpWebResponse)myHttpWebRequest.GetResponse();
    // Gets the stream associated with the response.
    Stream receiveStream = myHttpWebResponse.GetResponseStream();
    Encoding encode = System.Text.Encoding.GetEncoding("utf-8");
    // Pipes the stream to a higher level stream reader with the required encoding format.
    StreamReader readStream = new StreamReader( receiveStream, encode );
Console.WriteLine("\r\nResponse stream received.");
    Char[] read = new Char[256];
    // Reads 256 characters at a time.
    int count = readStream.Read( read, 0, 256 );
    Console.WriteLine("HTML...\r\n");
    while (count > 0)
        {
            // Dumps the 256 characters on a string and displays the string to the console.
            String str = new String(read, 0, count);
            Console.Write(str);
            count = readStream.Read(read, 0, 256);
        }
    Console.WriteLine("");
    // Releases the resources of the response.
    myHttpWebResponse.Close();
    // Releases the resources of the Stream.
    readStream.Close();

Remarks

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

Notiz

You must call one of the Stream.Close, Stream.Dispose, HttpWebResponse.Close, or HttpWebResponse.Dispose methods to close the stream and release the connection for reuse. It's not necessary to close or dispose both Stream and HttpWebResponse instances, but doing so doesn't cause an error. Failure to close or dispose the stream will cause your application to run out of connections.
