All the public methods of a Controller class are known as Action methods. They are similar to any other normal methods having the following restrictions:
1. Action method must be public. It cannot be private or protected
2. Action method cannot be overloaded
3. Action method can never be a static method.
4. Every controller has at least one default Action method Index() that returns the view page.
5. ActionResult is a base class of all the result type action methods.
This is an example of Index action method of StudentController
As we can see in the above example, Index method is a public method and it returns ActionResult using the View() method and The View() method is defined in the Controller base class, which returns the ActionResult.
