Hi,

Action Filter is an attribute which implements FilterAttribute class. ActionFilters in MVC are HandleError, OutputCache, ValidateInput, Authorize, ValidateAntyForgeryToken. Every one has its own functionality.

Implementation:
This is how to implement Action Filters,

[HandleError]
public class HomeController : Controller
{
public ActionResult Index()
{
ViewBag.Message = "Welcome to MVC";

return View();
}

public ActionResult About()
{
return View();
}
}


Hope this helps you.

Thanks & Regards,
Krishna
