How to use an area in asp net core

Introduction

ASP.NET is a popular programming language used for building web applications. One of the key features of ASP.NET is the ability to create and use areas, which allow you to organize your application into distinct sections or modules. In this article, we will explore how to use areas in ASP.NET Core.

Creating an Area

To create an area in ASP.NET Core, you need to follow a few simple . First, you need to add a new folder to your and name it according to the area you want to create. For example, if you want to create an area for user accounts, you can name the folder “Account”.

Next, you need to add a new class file to the area folder and name it “AreaRegistration.cs”. This class will be responsible for registering the area in your application. In this class, you need to inherit from the “AreaRegistration” class and override the “RegisterArea” method.


public class AccountAreaRegistration : AreaRegistration
{
    public override string AreaName => "Account";

    public override void RegisterArea(AreaRegistrationContext context)
    {
        context.MapRoute(
            name: "Account_default",
            : "Account/{controller=Home}/{action=Index}/{id?}"
        );
    }
}

In the “RegisterArea” method, you can use the “MapRoute” method to define the routing for your area. In the example above, we have defined a default route for the “Account” area, which maps to the “HomeController” and the “Index” action by default.

Using the Area

Once you have an area, you can using it in your application. To access the controllers and within the area, you need to specify the area name in the URL. For example, if you have created an area “Account”, you can access the “Index” action of the “HomeController” in the “Account” area using the following URL:


https://www.example.com/Account/Home/Index

In the example above, “https://www.example.com” is the base URL of your application, “Account” is the area name, “Home” is the controller name, and “Index” is the action name.
