Mvc 5 Exception Handling Use case The Controller.OnException method gives you a little bit more flexibility than the HandleErrorAttribute, but it is still tied to the MVC framework.

This method is called whenever there is an unhandled error in the controller. Here is a simple ELMAH tutorial. The first tab includes a stack trace: The next tab shows the query string parameters, if any: In this case, you can see the value of the throw parameter that check over here We will use Entity Framework Code first architecture.

You have this in addition to the regular page-based error handling mechanism. public class HomeController : Controller { protected override void OnException(ExceptionContext filterContext) { Exception ex = filterContext.Exception; filterContext.ExceptionHandled = true; var model = new HandleErrorInfo(filterContext.Exception, "Controller","Action"); filterContext.Result = new ViewResult() { ViewName The only reason not to use httpErrors is if you are still running on an older version of IIS (< 7.0). You should use more specific exception types whether built-in types such as InvalidOperationException and NullReferenceException or your own application specific types.

ASP.NET MVC offers several error handling techniques in addition to try...catch that you can use. In the BaseController's OnActionExecuting event, I log any exceptions that may have occurred: protected override void OnActionExecuted(ActionExecutedContext filterContext) { // Log any exceptions ILog log = LogManager.GetLogger(filterContext.Controller.GetType()); if (filterContext.Exception != null) Using the Try...Catch Statement To illustrate the try..catch technique, you will deliberately cause some database related exception. This may not be always possible and you may want to trap errors at the whole controller level.

The workaround to set the correct error code in the .aspx page works here as well.

C# [Serializable] public class LogAttribute : OnMethodBoundaryAspect { private static readonly Logger log = LogManager.GetCurrentClassLogger(); public LogAttribute() { AspectPriority = 20; } public override void OnEntry(MethodExecutionArgs args) { log.Debug("Entering {0}.{1}({2})", args.Method.DeclaringType.Name, Use the tag to configure the behaviour for one error code.
