What is the NonActionAttribute in mvc?

Point 1. All public methods inside an MVC controller are Action methods. Meaning, they can directly be accessed through url ex:-(/Home/index) where Index is an action method.

point 2. There are situations where we create methods just for business requirement and should not be accessible from url .

in the below example we are displaying employees from Index() action method, which gets the list from employees() method, employees() method should not be an action method as we don't want user to access this method. so we can mark it as non Action attribute.

public ActionResult Index()
{
var list=employees();
 return view(list);
}
 [NonAction]  
public List employees()
{
  return new List{new Employee(){id=1,Name='sachin'},new Employee(){id=2,Name='Test'}};
}
