Mvc Global Exception Handling
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.HttpApplication Navigating to the implementation of HttpApplication will reveal the underlying IHttpHandl

So, while something like an unknown http://stackoverflow.com/questions/15167927/how-do-i-log-all-exceptions-globally-for-a-c-sharp-mvc4-webapi-app endpoint (or action) is easily handled by using ELMAH or by adding something like this to the Global.asax: protected void Application_Error() { Exception unhandledException = Server.GetLastError(); //do more stuff } . . .unhandled errors that are not related to routing do not get logged. For example: public class ReportController : ApiController { public int test() { var foo = Convert.ToInt32("a");//Will throw error but isn't logged!! return foo; } } I have also tried setting the [HandleError] attribute globally by registering this filter: filters.Add(new HandleErrorAttribute()); But that also does not log all errors. Problem/Question How do I intercept errors like the one generated by calling /test above so that I can log them? It seems that this answer should be obvious, but I have tried everything I can think of so far. Ideally, I want to add some things to the error logging, such as the IP address of the requesting user, date, time, and so forth. I also want to be able to e-mail the support staff automatically when an error is encountered.
