Your  application xrds xml  was giving me issues  I was receiving a Content-Length of 0  no response    After removing that  you can access the response using response GetResponseStream     HttpWebRequest request   WebRequest Create  http   google com   as HttpWebRequest     request Accept    application xrds xml     HttpWebResponse response    HttpWebResponse request GetResponse     WebHeaderCollection header   response Headers   var encoding   ASCIIEncoding ASCII  using  var reader   new System IO StreamReader response GetResponseStream    encoding         string responseText   reader ReadToEnd

If you http request is Post and request Accept    application x-www-form-urlencoded   then i think you can to get text of respone by code bellow   var contentEncoding   response Headers  content-encoding                            if  contentEncoding    null  amp  amp  contentEncoding Contains  gzip       cause httphandler only request gzip                                                          using gzip stream reader                             using  var responseStreamReader   new StreamReader new GZipStream response GetResponseStream    CompressionMode Decompress                                                                  strResponse   responseStreamReader ReadToEnd                                                                                    else                                                          using ordinary stream reader                             using  var responseStreamReader   new StreamReader response GetResponseStream                                                                   strResponse   responseStreamReader ReadToEnd

I ve just tried that myself  and it gave me a 200 OK response  but no content - the content length was 0  Are you sure it s giving you content  Anyway  I ll assume that you ve really got content   Getting actual text back relies on knowing the encoding  which can be tricky  It should be in the Content-Type header  but then you ve got to parse it etc   However  if this is actually XML  e g  from  http   google com xrds xrds xml    it s a lot easier  Just load the XML into memory  e g  via LINQ to XML  For example   using System  using System IO  using System Net  using System Xml Linq  using System Web   class Test       static void Main                 string url    http   google com xrds xrds xml           HttpWebRequest request    HttpWebRequest  WebRequest Create url            XDocument doc          using  WebResponse response   request GetResponse                          using  Stream stream   response GetResponseStream                                  doc   XDocument Load stream                                      Now do whatever you want with doc here         Console WriteLine doc                If the content is XML  getting the result into an XML object model  whether it s XDocument  XmlDocument or XmlReader  is likely to be more valuable than having the plain text

The accepted answer does not correctly dispose the WebResponse or decode the text  Also  there s a new way to do this in  NET 4 5   To perform an HTTP GET and read the response text  do the following    NET 1 1 - 4 0  public static string GetResponseText string address        var request    HttpWebRequest WebRequest Create address        using  var response    HttpWebResponse request GetResponse                  var encoding   Encoding GetEncoding response CharacterSet            using  var responseStream   response GetResponseStream            using  var reader   new StreamReader responseStream  encoding               return reader ReadToEnd               NET 4 5  private static readonly HttpClient httpClient   new HttpClient     public static async Task lt string gt  GetResponseText string address        return await httpClient GetStringAsync address
