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

I believe it should be this code:

public class MyExceptionFilter : IExceptionFilter
{
    public void OnException(ExceptionContext filterContext)
    {
        filterContext.Result = new RedirectToRouteResult(new RouteValueDictionary(new { 
            action = "UserLogOut", 
            controller = "User", 
            area = "User" 
        }));

    }

}

You may add an additional "if (!filterContext.ExceptionHandled)" statement before logging the values inside the result to make sure that the exception's unhandled for the moment.
