"Error" Controller where his main action is "Index" (generic error page) and this controller will have a couple more actions for the errors that may appear to the user like "Handle500" or "HandleActionNotFound". So every error that may happen on the website may be handled by this "Error" Controller (examples: "Controller" or "Action" not found, 500, 404, dbException, etc). I am using Sitemap file to define website paths (and not route). This question was already answered, this is a reply to Gweebz My final applicaiton_error method is the following: protected void Application_Error() { //while my project is running in debug mode if (HttpContext.Current.IsDebuggingEnabled && WebConfigurationManager.AppSettings["EnableCustomErrorPage"].Equals("false")) { Log.Logger.Error("unhandled exception: ", Server.GetLastError()); } else { try { var exception = Server.GetLastError(); Log.Logger.Error("unhandled exception: ", exception); Response.Clear(); Server.ClearError(); var routeData = new RouteData(); routeData.Values["controller"] = "Errors"; routeData.Values["action"] = "General"; routeData.Values["exception"] = exception; IController errorsController = new ErrorsController(); var rc = new RequestContext(new HttpContextWrapper(Context), routeData); errorsController.Execute(rc); } catch (Exception e) { //if Error controller failed for same reason, we will display st

Do you mean that you want to catch and log unhandled exceptions? Do you want to log handled exceptions? Do you want to log conditions that are not exceptions, but still errors? You need to be a lot more specific about what you want. –Erik Funkenbusch Nov 9 '12 at 6:23 This article may help you prideparrot.com/blog/archive/2012/5/… –Mark Nov 9 '12 at 12:16 add a comment| 1 Answer 1 active oldest votes up vote 3 down vote P.S I am answering this with my understanding on this super generic question. 1 - Can some one please briefly explain about various methods of Error handling in MVC?

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 controller in mvc 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't exclude the other -- allow us to trap any exceptions raised around the controller code without having to write any explicit try/catch blocks. In particular, the OnException meth
allow us to handle errors in a very easy way. Just by decorating an action (or controller if we want to extend HandleError behaviour to all actions on that controller) with the HandleError attribute and enabling “CustomErrors” in web.config, we get a nice redirection to a friendly view in case an unhandled error raises. Internally, we could have a look at the implementation of OnException method inside HandleErrorusing Reflector to see how it works: As we can see, the unhandled exception will be handled if it hasn't been already marked as "handled" and if custom error handling is enabled . Web.config customErrors section The CustomErrors section allow us to define automatic error handling behaviour. If it doesn't exists, it must be created inside system.web section. as shown here: Posible values for mode are "Off | On | RemoteOnly". This will allow us to easy define behaviour for development and production scenarios : On: custom error handling enabled Off: custom error handling disabled. If an error is raised, we will see the yellow screen of death of ASP.NET RemoteOnly: if we launch the application in the local server (targeting http://localhost ), we won't see custom errors. If we access the applicationfrom other machine, we will see custom erros. This option is used by developers to debug applications. If there is an error, you can always (among other things) RD to your server and launch the application in a local browser so you see the exception in a first seat. Behaviour If we use the HandleError attribute and CustomErrors is enabled,w hen an unhandled error raises, the MVC runtimewill look for a “Errors.aspx” view in the context of the HttpRequest being processed (current view folder associated to controller or shared view folder), and will render it. In this case the "defaultredirect" and "redirect" CustomErrors attributes are igno
