Currently I'm using Restful service in asp.net c# and the following is the pdf string return that I get, I would like to convert it and save it as a .pdf file. How should I do it?

static string HttpGet(string url)
        {
            HttpWebRequest req = WebRequest.Create(url)
                                 as HttpWebRequest;
            string result = null;
            using (HttpWebResponse resp = req.GetResponse()
                                          as HttpWebResponse)
            {


                StreamReader reader =
                    new StreamReader(resp.GetResponseStream());
                result = reader.ReadToEnd();
            }
            return result;
        }

using (Stream stream = ... fetch the stream from somewhere)
{
    byte[] buffer = new byte[stream.Length];
    stream.Read(buffer, 0, buffer.Length);
    File.WriteAllBytes("foo.pdf", buffer);
}

and if this RESTful service talks HTTP you could use a WebClient:

using (var client = new WebClient())
{
    client.DownloadFile("http://example.com/api", "foo.pdf");
}
