errors, 404 errors, all errors due to a MySpecialDomainException and provide a default error page for all other errors (including errors in the IIS configuration!). All errors should return proper Razor views, it would be very nice to have an ErrorController in front of the views. E.g. something like this: public class ErrorController : Controller { public ViewResult NotFound () { return View(); } public ViewResult Forbidden () { return View(); } aspnet mvc 4 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ErrorModel { Exception = ex }); } } Currently you find many different ways to do that on the www, some most probably outdated.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|improve this question edited Jul 26 at 6:09 Mukesh Ram 2,7373625 asked Feb 24 '14 at 16:46 D.R. 6,14672271 I'm curious.. How exactly would you propose to have Razor pages when IIS is not configured correctly? If IIS isn't working, Razor won't be working... –Erik Funkenbusch Feb 24 '14 at 16:51 Yeah, probably it is not even possib

This is what I want to do: If the application crashes, or throws an error, it goes to a specific error page. I can throw my own error from the controller action. (and it goes to an error page). I found the following ways: I see there is a long way to do it here. (for v1 and v2 but also applies to v3). Using errorhandle attribute here. How do http://stackoverflow.com/questions/5995776/error-handling-in-asp-net-mvc-3 I handle this the proper way? If the solution is similar or is like #1 in the list above, I am using ninject and I have not created a base class.

Make sure that Error.cshtml Layout is not null. [It sould be something like: @{ Layout = "~/Views/Shared/_Layout.cshtml"; } Or remove Layout=null code block] A sample markup for Error.cshtml:- @{ Layout = "~/Views/Shared/_Layout.cshtml"; } @model System.Web.Mvc.HandleErrorInfo
Sorry, an error occurred while processing your request.
Controller Name: @Model.ControllerName
Action Name : @Model.ActionName
Message: @Model.Exception.Message
For Specific Error Handling Add HandleError attribute to specific action in controller class. Provide 'View' and 'ExceptionType' for that specific error. A sample NotImplemented Exception Handler: public class MyController: Controller { [HandleError(View = "NotImplErrorView", ExceptionType=typeof(NotImplementedException))] public ActionResult Index() { throw new NotImplementedException("This method is not implemented."); return View(); } } share|improve this answer edited Apr 17 '12 at 11:17 answered Apr 17 '12 atPortability Issues C++ & MFC » General Array Handling Binary Trees Bits and Bytes Buffer & Memory Manipulation Callbacks Classes and Class Use Collections http://www.codeguru.com/csharp/.net/net_asp/mvc/handling-errors-in-asp.net-mvc-applications.htm Compression Drag and Drop Events Exceptions External Links File I/O Function http://devproconnections.com/aspnet-mvc/aspnet-mvc-tutorial-handling-errors-and-exceptions Calling Linked Lists Memory Tracking Object Oriented Programming (OOP) Open FAQ Parsing Patterns Pointers Portability RTTI Serialization Singletons Standard Template Library (STL) Templates Tutorials Date & Time » General Date Controls Time Routines C++/CLI » .NET Framework Classes General ASP/ASP.NET Boxing and UnBoxing Components Garbage aspnet mvc Collection and Finalizers Interop Moving from Unmanaged Processes & Threads Templates Visual Studio .NET 2003 String Programming » General CString Alternatives CString Extensions CString Manipulation Open FAQ Regular Expressions String Arrays String Conversions .NET COM-based Technologies » ATL & WTL Programming » General ATL Active Scripting ActiveX Controls Database Debugging External links Graphics Support Misc. asp.net mvc 3 Performance Printing Tutorials Utilities Windows Template Library (WTL) ActiveX Programming » General Active Scripting ActiveX Controls ActiveX Documents Apartments & Threading Error Handling External links General COM/DCOM Misc.

You can easily deal with the first type of exceptions; however, you have to intervene in various places and use different tools to neutralize the impact of route exceptions and HTTP errors. In the end, you gain total control over runtime exceptions by writing error handlers within controllers and at least a global exception handler in global.asax. Let's find out the details and explore common practices for handling exceptions in ASP.NET MVC. Catching Exceptions in Controllers In controllers you write plain code, and in plain code you typically catch exceptions by using try/catch blocks. This approach gives you the most flexibility but at the cost of adding some noise to the code. Having a bunch of try/catch blocks scattered through a single method, though effective, makes reading the code a bit more difficult. The point here is not to question the importance of exception handling but simply to consider whether there's a better way of achieving the same results using easier-to-read code. Conveniently in this regard, Microsoft offers us the OnException overridable method and the HandleError filter attribute. Both methods -- and one method doesn'
