Controller (ASP.NET MVC)

In ASP.NET MVC, a Controller is responsible for handling incoming requests and returning the appropriate response. In this page, we will discuss Controllers and its key features.

Syntax

The syntax for creating a Controller in ASP.NET MVC is as follows:

public class MyController : Controller {
    public ActionResult Index() {
        // Code logic here
        return View();
    }

    // Additional Actions
}

Example

Here's an example of a simple Controller:

public class HomeController : Controller {
    public ActionResult Index() {
        return View();
    }

    public ActionResult About() {
        ViewBag.Message = "Your application description page.";

        return View();
    }

    public ActionResult Contact() {
        ViewBag.Message = "Your contact page.";

        return View();
    }
}

Output

When you first create an ASP.NET MVC project, it will include a default Controller and Views. The output of running an application with this Controller is a web page with links to the About and Contact actions.

Explanation

A Controller in ASP.NET MVC is responsible for handling incoming requests and returning the appropriate response. Actions are methods within Controllers that handle specific HTTP requests. These actions can return different types of responses such as views, JSON or XML data.

A Controller can also communicate with the Model to get or save data. The Model is responsible for representing the data as objects and providing access to that data for the Controller. The View is responsible for rendering the output to the user.

Use

Controllers can be used in ASP.NET MVC to handle user requests and serve appropriate content to the user. They can provide access to data sources and use them to generate responses such as views, JSON or XML data.

Important Points

  • A Controller handles incoming requests and returns the appropriate response.
  • Actions are methods within Controllers that handle specific HTTP requests.
  • The Model is used to provide access to data sources.
  • The View is responsible for rendering the output to the user.
