Currently in my project I have a controller called Error with action methods HTTPError404(), HTTPError500(), and General(). They all accept a string parameter error. Using or modifying the code below. mvc 5 error handling 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 55139 asked Jul 23 '09 at 11:07 aherrick 7,7481772115 add a comment| 9 Answers 9 active oldest votes up vote 80 down vote accepted Instead of creating a new route for that, you could just redirect to your controller/action and pass the information via querystring.

All errors should return proper Razor views, it would be very nice to have an ErrorController in http://stackoverflow.com/questions/21993758/asp-net-mvc-5-error-handling front of the views. E.g. something like this: public class ErrorController : Controller { public ViewResult NotFound () { return View(); } public ViewResult Forbidden () { return View(); } public ViewResult Default () { var ex = ObtainExceptionFromSomewhere(); if(ex is MySpecialDomainException) return View("MySpecialDomainException", new ErrorModel { Exception = ex }); return View("GeneralError", new ErrorModel { Exception = ex }); } } Currently you find many different ways to do that on the www, some most probably outdated. Among those: Controller.OnException() Error filter customErrors element in web.config Handling in Global.asax's Application_Error Q1: What is the recommended way to fulfill our requirements with ASP.NET MVC 5? Also we want to catch errors occurring in the IIS host. Q2: To prevent that IIS has to handle any 404s we thought about adding a default route matching all possible URLs - is this recommendable? Better to register instead for IIS' 404s as well? Q3: Is it even possible to register an IIS error page which goes back to a controller, or is IIS capable of ASPX / static HTML only? c# asp.net-mvc error-handling asp.net-mvc-5 asp.net-mvc-5.1 share|imp
it as part of our official documentation for implementing custom error pages, we've decided to sponsor it.

Custom error pages and global error logging are two elementary and yet very confusing topics in ASP.NET MVC 5. There are numerous ways of implementing error pages in ASP.NET MVC 5 and when mvc error you search for advice you will find a dozen different StackOverflow threads, each suggesting a different implementation. Overview What is the goal? Typically good error handling consists of: Human friendly error pages Custom error page per error code (e.g.: 404, 403, 500, etc.) Preserving the HTTP error code in the response to avoid mvc error handling search engine indexing Global error logging for unhandled exceptions Error pages and logging in ASP.NET MVC 5 There are many ways of implementing error handling in ASP.NET MVC 5. Usually you will find solutions which involve at least one or a combination of these methods: HandleErrorAttribute Controller.OnException Method Application_Error event customErrors element in web.config httpErrors element in web.config Custom HttpModule All these methods have a historical reason and a justifyable use case. There is no golden solution which works for every application. It is good to know the differences in order to better understand which one is applied best. Before going through each method in more detail I would like to explain some basic fundamentals which will hopefully help in understanding the topic a lot easier. ASP.NET MVC Fundamentals The MVC framework is only a HttpHandler plugged into the ASP.NET pipeline. The easiest way to illustrate this is by opening the Global.asax.cs: public class MvcApplication : System.Web
