Update – for folks who learn best visually, I’ve posted a follow-up screencast of the demo steps discussed below, as a DevNuggets video. You can view the video here. mvc exception filter What’s an Action Filter? If you’re just getting started with ASP.NET MVC, you may exception filter in mvc 5 have heard of something called action filters, but haven’t had the chance to use them yet. Action filters provide a convenient mechanism

for attaching code to your controllers and/or action methods that implements what are referred to as cross-cutting concerns, that is, functionality that isn’t specific to one particular action method, but rather is something you’d want http://stackoverflow.com/questions/5995776/error-handling-in-asp-net-mvc-3 to re-use across multiple actions. An action filter is a .NET class that inherits from FilterAttribute or one of its subclasses, usually ActionFilterAttribute, which adds the OnActionExecuting, OnActionExecuted, OnResultExecuting, and OnResultExecuted methods, providing hooks for code to be executed both before and after the action and result are processed. Because action filters are subclasses of the System.Attribute class (via either FilterAttribute or one of its subclasses), they can be applied to https://blogs.msdn.microsoft.com/gduthie/2011/03/17/get-to-know-action-filters-in-asp-net-mvc-3-using-handleerror/ your controllers and action methods using the standard .NET metadata attribute syntax: C#: 1: [MyNamedAttribute(MyParam = MyValue)] 2: public ActionResult MyActionMethod() 3: { 4: // do stuff 5: } VB: 1: _ 2: Public Function MyActionMethod() As ActionResult 3: ' do stuff 4: End Function This makes action filters an easy way to add frequently-used functionality to your controllers and action methods, without intruding into the controller code, and without unnecessary repetition. To be clear, action filters aren’t new to MVC 3, but there’s a new way to apply them in MVC 3 that I’ll discuss later on in this post. What’s in the Box? ASP.NET MVC provides several action filters out of the box: Authorize – checks to see whether the current user is logged in, and matches a provided username or role name (or names), and if not it returns a 401 status, which in turn invokes the configured authentication provider. ChildActionOnly – used to indicate that the action method may only be called as part of a parent request, to render inline markup, rather then returning a full view template. OutputCache – tells ASP.NET to cache the output of the requested action, and to serve the cached output based on the parameters provided. HandleError – provides a me

Effectively in ASP.NET MVC 10 April 2014Handling Errors Effectively in ASP.NET MVCASP.NET MVC gives you more options in the way that you handle exceptions. Error handling isn't intrinsically exciting, but there are many ways of avoiding the classic yellow page of death, even getting ELMAH to manage error handling for you. 79 3 Dino Esposito Years ago, ASP.NET's error handling was one of the major things that made me wonder if ASP.NET MVC could give me something that ASP.NET Web Forms couldn't. Web Forms is based on pages; so if something goes wrong, all that you can do is to redirect the user to another page and explain what the error was or just be generically sorry. ASP.NET Web Forms allow you to map an error page for each possible HTTP status code. You control the mapping through the section of the web.config file. Because of the different architecture of the view in ASP.NET MVC, it is possible to save the redirect command and then programmatically switch to an error view in the context of the same request. You have this in addition to the regular page-based error handling mechanism. I wouldn't use HTTP code redirects in ASP.NET MVC; but only because more flexible solutions are possible. Generally speaking, error handling in ASP.NET MVC is mainly necessary to handle program and route exceptions. Program exceptions refer to catching errors in controllers and in any code you may have in Razor views. Route exceptions refer to missing links and invalid URLs. Program Exceptions Any stack trace you can have out of an ASP.NET MVC application originates from a method call in a controller class. The controller class, therefore, is where any exceptions in your ASP.NET MVC code can be trapped. You can do that in a number of equivalent ways. For example, you can have a try/catch block surrounding the entire method body. It works, but it's ugly to see
