从网页上读过来的html代码显示在控制台上是乱码，这个如何解决

/// <summary>        /// 根据ulr读出html        /// </summary>        static string GetHtml(string url)        {            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);            HttpWebResponse response = (HttpWebResponse)request.GetResponse();            Stream stream = response.GetResponseStream();            StreamReader sReader = new StreamReader(stream, Encoding.Default);            string html = sReader.ReadToEnd().Replace("\r\n", "");            response.Close();            Console.WriteLine(html);            return html;        }
