ASP.NET MVC5如何捕获所有的System.NullReferenceExceptions并重定向到一个视图，这样我的程序就不会崩溃？

public class CustomExceptionFilter : HandleErrorAttribute
{
    public override void OnException(ExceptionContext filterContext)
    {
        if (filterContext.Exception is NullReferenceException)
        {
            filterContext.ExceptionHandled = true;
            filterContext.Result = new ViewResult
            {
                ViewName = "NullReferenceError", // 重定向到的视图名称
                ViewData = filterContext.Controller.ViewData,
                TempData = filterContext.Controller.TempData
            };
        }
    }
}

protected void Application_Start()
{
    // ...

    GlobalFilters.Filters.Add(new CustomExceptionFilter());
}
