HttpWebResponse对gzip格式返回结果的处理

  HttpWebRequest webRequest = (System.Net.HttpWebRequest)System.Net.WebRequest.Create(url); 



HttpWebResponse webResponse = (System.Net.HttpWebResponse)webRequest.GetResponse();





            Stream streamReceive = webResponse.GetResponseStream();



  if (webResponse.ContentEncoding.ToLower().Contains("gzip"))

                {

                    //gzip格式

                    streamReceive = new GZipStream(streamReceive, CompressionMode.Decompress);

                }



 using (System.IO.StreamReader sr = new System.IO.StreamReader(streamReceive, encoding))

                {

                    responseData = sr.ReadToEnd();

                }
