Selectors , Models , Helpers in MVC : Part 3

Selectors

• Action selectors are the attributes that help action method to be invoked to a particular request

There are three types of action selectors

• Action Name
• Non Action
• Action Verb

Action Name

It is used to give name for an action. It allows developers to use different action name than method name

e.g.

[ActionName("CurrentTime")]

public string GetCurrentTime()

{

}

Non Action

This is a built in attribute which is used to indicate that the method is not an action.

e.g.

[NonAction]

public string GetTime()

{

}

ActionVerb

Another selector field that can be applied is Action Verb

• HttpGet
• HttpPost
• HttpPut
• HttpDelete
• HttpOptions
• HttpPatch

If the two action method are declared with same name but with different action verb than it will respond to that particular action verb.

Model in MVC

A model stores a data that is fetched according to commands from controller and displayed in view.

Helpers

Helpers are used to create HTML controls and elements programatically.
