HttpWebRequest scope response stream

There is no easy way to safely return a Stream without leaking resources. The main problem is removing WebResponse:

public Stream Load(string term)
{
    var url = CreateSearchUrl(term);

    var webRequest = (HttpWebRequest)WebRequest.Create(url);
    var webResponse = webRequest.GetResponse(); // whoops this doesn't get disposed!

    return new GZipStream(webResponse.GetResponseStream(), CompressionMode.Decompress);
}

Closing WebResponse is actually more important than closing the response stream, since closing WebResponse implicitly closes the response stream.

, WebResponse Stream, - GZipStream, WebResponse ( GZipStream), . , :

class WebResponseDisposingStream : Stream
{
    private readonly WebResponse response;
    private readonly Stream stream;

    public WebResponseDisposingStream(WebResponse response, Stream stream)
    {
        if (response == null)
            throw new ArgumentNullException("response");
        if (stream == null)
            throw new ArgumentNullException("stream");

        this.response = response;
        this.stream = stream;
    }

    public override void Close()
    {
        this.response.Close();
        this.stream.Close();
    }

    // override all the methods on stream and delegate the call to this.stream

    public override void Flush() { this.stream.Flush(); } // example delegation for Flush()
    // ... on and on for all the other members of Stream
}

public void Load(string term, Action<Stream> action)
{
    var url = CreateSearchUrl(term);

    var webRequest = (HttpWebRequest)WebRequest.Create(url);

    using (var webResponse = webRequest.GetResponse())
    using (var responseStream = webResponse.GetResponseStream())
    using (var gzipStream = new GZipStream(responseStream, CompressionMode.Decompress))
    {
        action(gzipStream);
    }
}

Load("test", stream => Console.WriteLine("Length=={0}", stream.Length));
