with it? It's easier than looking for exceptions in input as it is very rare when this happens. c# http-status-code-404 httpwebresponse share|improve this question asked Dec 7 '09 at 2:44 Skuta 2,253224964 add a comment| 3 Answers 3 active oldest votes up vote 25 down vote accepted I'm assuming you have a line somewhere in your code like: HttpWebResponse response = request.GetResponse() as HttpWebResponse; Simply replace it with this: HttpWebResponse response; try { response remote server returned an error 404 not found wcf = request.GetResponse() as HttpWebResponse; } catch (WebException ex) { response = ex.Response as HttpWebResponse; } share|improve this answer answered Dec 7 '09 at 3:08 Adam Maras 17.5k23978 I meant to read the 404 document as if it was a normal because I'm parsing it, it just won't go through regexes... –Skuta Dec 7 '09 at 10:39 Yes, this will do just that. After this block of code executes, response will be the response stream from whatever was returned, no matter what the HTTP status code is. –Adam Maras Dec 7 '09 at 11:15 3 Remeber that HttpWebResponse is IDisposable and needs to be wrapped in using block, otherwise you will hit concurrent http request limit. –skolima Jul 9 '13 at 21:40 Instead of the using calling response.Close() is enough? –martinbc Oct 1 '14 at 20:22 Adam, this solved my issue, but why does it work? If it isn't found, how can it be in the exception details? Well known Microsoft secret? –jp2code Nov 23 '15 at 17:15 | show 1 more comment Did you find this question interesting?

Join them; it only takes a minute: Sign up HttpWebRequest.GetResponse() returning 404 Error up vote 0 down vote favorite I have some http://stackoverflow.com/questions/1857512/httpwebresponse-returns-404-error code that calls HttpWebRequest's GetResponse() method to retrieve HTML from a URL and return it to the calling method. This has been working perfectly fine within my Development and QA environments but now that I have uploaded it to my UAT server, I keep getting the following error: The remote server returned an error: (404) Not Found. The main difference between Dev/QA and UAT is that UAT uses SSL/HTTPS http://stackoverflow.com/questions/28396989/httpwebrequest-getresponse-returning-404-error based URLs whereas Dev/QA uses HTTP. I introduced the following line of code to help progress me a little futher: ServicePointManager.ServerCertificateValidationCallback = new System.Net.Security.RemoteCertificateValidationCallback(AcceptAllCertifications); where AcceptAllCertifications always returns true but I still get my 404 error. I that people who previously had this error have been able to resolve the issue by merely ensuring the URI used for the HttpWebRequest doesn't have a slash at the end (see: Simple HttpWebRequest over SSL (https) gives 404 Not Found under C#) but this does not make a difference to me. I have now tried what was suggested at this post (see: HttpWebResponse returns 404 error) where I render the exception on the page. This bypassed the yellow-warning screen and gives me a bit more informtion, including the URL it is trying to get a response from. However, when I copy and paste the URL into my browser, it works perfectly fine and renders the HTML on the page. I'm quite happy therefore that the correct URL is being used in the GetResponse call. Has anyone got any ideas as to what may be causing me this grief? As said, it only seems to be a problem on my UAT server where I am using SSL. Here is my cod

The WebExceptionStatus.ProtocolError can only detect that an error occurred, but not give the exact code of the error. For example: catch (WebException ex) { if (ex.Status != WebExceptionStatus.ProtocolError) { throw ex; } } Is just not useful enough... the protocol exception could be 401, 503, 403, anything really. c# .net exception-handling error-handling http-status-code-404 share|improve this question remote server returned edited Jan 7 '14 at 19:45 John Saunders 138k20177323 asked Dec 22 '09 at 22:25 JL. 23.6k88246391 11 NNNOOOOOOOOOOOOO! Don't catch System.Exception, and don't depend on the exception text in your handler! –Aaronaught Jan 28 '10 at 16:09 2 So what would you recommend? –Luke101 Jan 28 '10 at 16:11 2 John Saunders' answer was the most complete. I think people just downvoted him out of spite. –Aaronaught Jan 28 '10 at 16:15 2 Don't use throw ex, you'll generate a new exception with an empty call stack. Just use throw. –krbnr Dec 17 '14 at 19:07 add a comment| 11 Answers 11 active oldest votes up vote 74 down vote accepted Use the HttpStatusCode Enumeration, specifically HttpStatusCode.NotFound Something like: HttpWebResponse errorResponse = we.Response as HttpWebResponse; if (errorResponse.StatusCode == HttpStatusCode.NotFound) { // } Where we is a WebException. share|improve this answer answered Dec 22 '09 at 22:32 Jay Riggs 39.4k685118 Yes, that's ideal... worked like a charm, thanks again! –JL. Dec 22 '09 at 22:35 can I get the NUMBER out somehow from the objects without making my own lookup list? I would like to have something like: int httpresponsecode = HttpStatusCode.ToInt() or similar so I get 404 –BerggreenDK Apr 12 '11 at 14:42 2 @BerggreenDK you should be able to just do int htt
