C# Throw 403 Exception
vote favorite 2 I have got a web service programmed in c# / asp.net. [WebService(Namespace = "http://example.com/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] [ScriptService] [System.ComponentModel.ToolboxItem(false)] public class Service: System.Web.Services.WebService { [WebMethod] [ScriptMethod(ResponseFormat = ResponseFormat.Json)] public Result GetData() { User user = GetUser(); if (user.LoggedIn) { return GetData(); } else { // raise exception -> return error 403 } } How is it possible to return error 403 out of this web service? I can asp.net mvc throw 403 throw an exception - but this shows the exeption and not his error. Any ideas? c# asp.net web-services http-status-code-403 share|improve this question edited Apr 13 '11 at 13:56 asked Apr 13 '11 at 13:13 bernhardrusch 5,80573452 You return value from service only if user is 'LoggedIn' you must return that 'Result' type from that method. –1110 Apr 13 '11 at 13:28 and how do I return this 'Result' type ? –bernhardrusch Apr 13 '11 at 13:40 You declare your method to return 'Result' type. And you must return object of that type from your method. What is 'Data()'? You cant return something from only one 'if' block, because if that block is false your method will not return anything. –1110 Apr 13 '11 at 13:49 I thought I can raise an exceptino or something like this and then the web service would return 403 –bernhardrusch Apr 13 '11 at 13:55 Code 401 would be more appropriate as the user could access the resource if he loggs in –Daniel Mar 15 '13 at 10:16 add a comment| 8 Answers 8 active oldest votes up vote 18 down vote You don't need to set both Context.Response.Status and Context.Response.StatusCode. Simply setting Context.Response.StatusCode = (int)System.Net.HttpStatusCode.
April 30, 2012 Apr 302012 Share...0000000 Here is the problem: How to properly display a user-friendly error message for an exception being thrown from an ASP.NET Web web api return forbidden Service? I know that we shouldn't be really working anymore with http status 403 forbidden error when trying to access webservice ASP.NET Web Services as a huge amount of problems have been solved with the WCF framework. But, actionresult 403 for those like me, that are working on some large-scale projects where we are still using some old technology this could be an interesting post. I was kind of http://stackoverflow.com/questions/5649852/asp-net-web-service-i-would-like-to-return-error-403-forbidden surprised the first time I saw an exception being thrown from the ASP.NET Web Service and how it looked ugly when the error Message Box appeared on the Client application (GUI). The Exception.Message contained the internal Web Service stack. The server-side code looked like this: [WebMethod] public SomeResultObject SomeWebMethod() { try { /* code here */ } catch http://www.agile-code.com/blog/asp-net-web-service-returning-properly-formatted-error-message/ (Exception ex) { /* Some logging logic here...*/ throw; //this would simply throw an SoapException } } The first thing I tried was to throw my Exception, and not just re-throwing, but this was not helping at all as I soon realized that all the exceptions thrown by the SomeWebMethod() would be wrapped internally by the .NET framework, and the SoapException would be thrown instead. The first approach - Client side My first approach of solving this problem was then to change the Client (GUI) application and display a generic error message, no matter what has been thrown by the Web Service. Obviously this was a bad choice, as there were so many conditions and error messages that the end-user needed to know about. So, this approach would probably work for someone, but unfortunately didn't work for me: public void WebServiceCallMethod() { try { /* Calling the web service here */ } catch(SoapException exc) { MessageBox.Show("An error happened while processing your call"); } } Parsing the exc.Message in order to

To accomplish this, we need to raise SOAP exceptions from the Web service that are compliant with the SOAP specification. The following are the advantages
