Join them; it only takes a minute: Sign up HttpWebRequest WebException ProtocolError up vote 2 down vote favorite I'm trying to understand something about c# protocolerror exception handling with a HttpWebRequest. I have a client library and it's making a request to a WebAPI controller; HttpWebRequest r = (HttpWebRequest)WebRequest.Create(url); r.Method = "POST"; r.ContentType = "application/json"; foreach (var header in request.Headers) { r.Headers.Add(header.Key, header.Value.ToString()); } r.ContentLength = request.RequestBody.Length; using (StreamWriter writer = new StreamWriter(r.GetRequestStream())) writer.Write(request.RequestBody); I know the request will throw an exception, and contain the message "entity already exists - 1234". When I get the response; using
Protocol Error 400 Bad Request
(HttpWebResponse response = (HttpWebResponse)r.GetResponse()) { if (response.StatusCode == HttpStatusCode.OK) using (StreamReader reader = new StreamReader(response.GetResponseStream())) return reader.ReadToEnd(); return "Invalid"; } I get a WebException thrown. So, the caller of the request has a try..catch in it. And I get the WebException. What I get is a protocol error, not the 500 internal server error that was thrown (using correct status codes to represent the message comes later). Now if I read the Response of the WebException, it does contain my message and the stacktrace. Questions Why do I not get a status code of 500 in my response, why does it throw a protocol error? Is there a more correct way of handling the request? I have searched around and found some people getting this issue when not using the correct headers etc. But as far as I can tell, I have added all the headers that I can and still get the same behavior. c# asp.net-web-api httprequest share|improve this question edited Sep 26 '14 at 15:38 Alex K. 107k16149195 asked Sep 26 '14 at 15:19 Hammerstein 1,8051033 500 is an error code as specified in the HTTP protocol; the exception means "The protocol I'm using signalled an error".
