C# MVC

Introduction to C# MVC

The Model-View-Controller (MVC) pattern is a design framework for building web applications. In C#, the MVC framework is part of the ASP.NET environment, providing a structured way to manage the application’s data, presentation, and user interaction.

By separating an application into three main components—the Model, the View, and the Controller—MVC helps you manage complexity, foster a clean code architecture, and enhance testability.

Understanding the Model-View-Controller Pattern

The MVC pattern divides the application into three interconnected components:

• Model: Represents the application's data and business logic.
• View: Handles the display of information or the user interface.
• Controller: Acts as an intermediary between the Model and View, processing user input and updating the Model and View accordingly.

Setting Up a C# MVC Project

To start using MVC in C#, you'll first need to set up a new ASP.NET Core application. Here's a quick guide to getting started:

This command creates a new ASP.NET Core MVC project named MyMvcApp. The project contains the necessary folders and files, such as Controllers, Views, and Models.

Creating a Controller

The Controller is responsible for handling incoming requests, processing them, and returning the appropriate response. Let's create a simple controller in our project:

In this example, a HomeController is created with an Index action method. When a request is made to the root URL of the application, the Index method is called, rendering the corresponding view.

Developing Views

Views in MVC are used to present data to the user. They are typically written using Razor syntax. Here's how you can create a view for the Index action method:

Create a new file named Index.cshtml in the Views/Home directory. The above Razor syntax is used to set the title and display a welcome message.

Working with Models

Models represent the data and business logic of your application. Here's a simple example of a Model in C# MVC:

The Product class represents a model with three properties: Id, Name, and Price. This model can be used to represent product data in your application.

Conclusion

C# MVC is a powerful framework that helps developers build well-structured web applications. By organizing your application into models, views, and controllers, you can achieve a clean separation of concerns, making your code more manageable and testable.
