What is Controller in Asp.Net Core MVC in English and Hindi
Controller in Asp.Ner Core MVC in English
In ASP.NET Core MVC, a controller is a fundamental component that handles incoming requests from clients, processes the requests, and generates appropriate responses. It acts as an intermediary between the user interface and the application's logic, facilitating the flow of data and interactions.
Controllers in ASP.NET Core MVC are responsible for:
Receiving Requests: When a user interacts with a web application, such as by clicking a link or submitting a form, a request is sent to the server. The appropriate controller is then responsible for processing this incoming request.
Processing Logic: Controllers contain methods (also known as action methods) that encapsulate the logic required to fulfill the request. This can involve querying a database, interacting with services, processing data, and making decisions based on the request parameters.
Communicating with Views: After processing the request, controllers interact with the view layer to generate the appropriate response to be sent back to the client. They can pass data to the view, which then renders the data in the desired format (usually HTML).
Managing Routing: Controllers are associated with specific routes in the application's routing configuration. The routing system directs incoming requests to the appropriate controller and action method based on the URL structure.
Overall, controllers play a pivotal role in the MVC (Model-View-Controller) architectural pattern by separating concerns and promoting a structured way to organize the application code. They help maintain separation of concerns by isolating the logic that handles user interactions from the underlying data and presentation layers.
Let's say you're building a basic to-do list application. You want to create a controller to handle tasks. Here's how you might define a controller and an action method:
Create a new controller class named TaskController.cs:
Create a view to display the tasks. Create a file named Index.cshtml in the Views/Task directory:
In this example, the TaskController class defines an action method named Index. When a user navigates to the URL associated with this action (e.g., /Task/Index), the Index action method is executed. It retrieves tasks (which can come from a database or another data source) and passes them to the corresponding view for rendering.
The view, Index.cshtml, receives the list of tasks and iterates through them to display their titles and completion status.
This demonstrates the basic concept of how a controller handles requests, processes logic, and communicates with views in ASP.NET Core MVC.
Controller in Asp.Ner Core MVC in Hindi
Controller ek software component hota hai jo web applications mein aane wale requests ko handle karta hai. Ye requests ko receive karta hai, unka processing karta hai, aur unke liye sahi response generate karta hai. Controller user interface aur application ke logic ke beech ek bridge ki tarah kaam karta hai.
ASP.NET Core MVC mein, controllers user ke interactions ko manage karte hain. Ye requests ko samajhte hain, unka logic process karte hain, aur views ke saath communicate karte hain taki final response generate ho sake. Inka main kaam application ke code ko organized aur maintainable rakhna hota hai.
