How to use Exception filters in MVC 5

Question

How i can implement Exception Filters in MVC5.

I want to throw the exception to NLog and redirect the page to a default error page which displays \"Something is gone

Answer 1

You could derive your own HandleErrorAttribute

public class NLogExceptionHandlerAttribute : HandleErrorAttribute
{
    public override void OnException(ExceptionContext filterContext)
    {
        // log error to NLog
        base.OnException(filterContext);
    }
}

Then register it globally

public static void RegisterGlobalFilters(GlobalFilterCollection filters)
{
    filters.Add(new NLogExceptionHandlerAttribute());
    ...
}

By default, the HandleErrorAttribute will display the Error view located in the ~/Views/Shared folder but if you wanted to display a specific view you can set the View property of the attribute.
