Controller:

   public class GlobalOverflowExceptionController : Controller
    {
        //
        // GET: /GlobalOverflowException/

        public ActionResult Index()
        {
            return View();
        }
        public ActionResult overflowexception()
        {

            int value = int.MaxValue + int.Parse("1");

            if (value < 0)
            {
                throw new OverflowException();

            }
            else
            {
                ViewBag.Result = value;
            }
            return View();
        }

        public ActionResult dividebyzeroexception()
        {


            int a = 10;
            int b = 0;
            int c = a / b;
            return View();
        }

        public ActionResult overflowexception1()
        {

            int value = int.MaxValue + int.Parse("1");

            if (value < 0)
            {
                throw new OverflowException();

            }
            else
            {
                ViewBag.Result = value;
            }
            return View();
        }

    }

HandleErrorAttribute at controller level

Controller:

    [HandleError(ExceptionType = typeof(System.OverflowException), View = "overflowexception")]
    public class OverflowExceptionController : Controller
    {
        //
        // GET: /OverflowException/

        public ActionResult Index()
        {
            return View();
        }
    
        public ActionResult overflowexception()
        {

            int value = int.MaxValue + int.Parse("1");

            if (value < 0)
            {
                throw new OverflowException();

            }
            else
            {
                ViewBag.Result = value;
            }
            return View();
        }
    
        public ActionResult dividebyzeroexception()
        {


            int a = 10;
            int b = 0;
            int c = a / b;
            return View();
        }
      
        public ActionResult overflowexception1()
        {

            int value = int.MaxValue + int.Parse("1");

            if (value < 0)
            {
                throw new OverflowException();

            }
            else
            {
                ViewBag.Result = value;
            }
            return View();
        }
    }

View:
