the errors that are not caught with a Try/Catch block or in a page-level error handler. In the example, the handler transfers control to a generic error page named GenericErrorPage.aspx, which interprets the error and displays an appropriate message. Example The following example is from a complete code sample in Complete Example for Error Handlers. Security Note Never set customErrors to Off in your Web.config file if you do not have an Application_Error handler in your Global.asax file. Potentially compromising information about your Web site can be exposed to anyone who can cause an error to occur on your site.

Exception exc = Server.GetLastError(); // Handle HTTP errors if (exc.GetType() == typeof(HttpException)) { // The Complete Error Handling Example generates // some errors using URLs with "NoCatch" in them; // ignore these here to simulate what would happen // if a global.asax handler were not implemented. if (exc.Message.Contains("NoCatch") || exc.Message.Contains("maxUrlLength")) return; //Redirect HTTP errors to HttpError page Server.Transfer("HttpErrorPage.aspx"); } // For other kinds of errors give the user some information // but stay on the default page Response.Write("

Currently in my project I have a http://stackoverflow.com/questions/1171035/asp-net-mvc-custom-error-handling-application-error-global-asax controller called Error with action methods HTTPError404(), HTTPError500(), and General(). They all accept a string parameter error. Using or modifying the code below. What is the best/proper way to pass the data to the Error controller for processing? I would like to have a robust solution as possible. protected void Application_Error(object sender, EventArgs e) { Exception exception = Server.GetLastError(); Response.Clear(); HttpException httpException = exception as HttpException; if (httpException != null) { RouteData routeData = new RouteData(); routeData.Values.Add("controller", "Error"); switch (httpException.GetHttpCode()) { case 404: // page not found routeData.Values.Add("action", "HttpError404"); break; case 500: // server error routeData.Values.Add("action", "HttpError500"); break; default: routeData.Values.Add("action", "General"); break; } routeData.Values.Add("error", exception); // clear error on server Server.ClearError(); // at this point how to properly pass route data to error controller? } } c# asp.net asp.net-mvc error-handling user-experience share|improve this question edited Sep 10 '14 at 17:54 Oualid KTATA 52138 asked Jul 23 '09 at 11:07 aherrick 7,6731771115 add a comment| 9 Answers 9

Here's how it looks: Global.asax: protected void Application_Error(object sender, EventArgs e) { Exception ex = Server.GetLastError(); string path = "N/A"; if (sender is error handling application_error HttpApplication) path = ((HttpApplication) sender).Request.Url.PathAndQuery; string args = string.Format("Path: {0}", path); // Custom code that generates an HTML-formatted exception dump string message = Email.GenerateExceptionMessage(ex, args); // Custom code that sends an email to the dev team. Email.SendUnexpectedErrorMessage("Some App", message); } One "minor" problem, though - when I intentionally have a part of the code throw an exception in order to test this mechanism... public static void GetMuffinsByTopping(string topping) { throw new Exception("Test Exception!", new Exception("Test Inner Exception!!!")); // Actual repository code is unreachable while this test code is there } The front-end JavaScript is immediately intercepting an HTTP 500 request, but the global.asax.cs code noted above is not being reached (I set a breakpoint on the first executing line of the method.) Question: In what way can I get the "old" Application_Error handler to dispatch error emails, so that our team's developers can more easily debug our application? c# asp.net-web-api error-reporting share|improve this question asked Feb 27 '15 at 15:34 Andrew Gray 1,3701630 1 You could abstract your error handling logic into a separate method that Application_Error calls, wrap the Web API method body in a try/catch, then manually pass the error logic to the abstracted method from Web API errors. Not the cleanest way I'm sure, but it should be strai
