Introduction

Welcome to our guide on building a shopping cart application using C# project! If you’re looking to dive into the world of software development or enhance your coding skills, you’re in the right place.

In this tutorial, we’ll walk you through the process of creating a fully functional shopping cart system using C#.

Getting Started with C# Shopping Cart

So, you’re ready to embark on your journey to create a shopping cart application in C#. Before we dive into coding, let’s take a quick look at what a shopping cart is and why it’s essential. 🤔

What is a Shopping Cart?

In the realm of e-commerce, a shopping cart is like your virtual basket in a physical store. It allows users to select and store items they intend to purchase while browsing through an online store.

It keeps track of the chosen products, quantities, and prices, enabling customers to review and modify their selections before proceeding to checkout.

Why Build a Shopping Cart in C#?

Now, you might be wondering, why C#? Well, C# project is a powerful and versatile programming language commonly used for building various types of applications, including web applications, desktop software, and games.

Its syntax is easy to understand, making it an excellent choice for beginners and seasoned developers alike. Plus, with the .NET framework’s extensive libraries and tools, developing robust and scalable applications becomes a breeze.

Building the Shopping Cart Application

Alright, it’s time to roll up our sleeves and start coding! But first, let’s outline the key components of our shopping cart application.

Classes in C# Project Shopping Cart

Our shopping cart application will consist of two main classes: ShoppingCart and Product. These classes will handle the management of products and the shopping cart itself. Here’s a brief overview of each class:

ShoppingCart Class

The ShoppingCart class represents the shopping cart and manages the list of products. It provides methods to add and remove products, clear the cart, and calculate the total cost of all items in the cart.

• List<Product> products: This private member variable holds the list of products in the shopping cart.
• AddProduct(Product product): Adds a product to the shopping cart.
• RemoveProduct(Product product): Removes a product from the shopping cart.
• ClearCart(): Clears the shopping cart by removing all products.
• CalculateTotal(): Calculates the total price of all products in the cart.

public class ShoppingCart
{
    private List<Product> products;

    public ShoppingCart()
    {
        products = new List<Product>();
    }

    public void AddProduct(Product product)
    {
        products.Add(product);
    }

    public void RemoveProduct(Product product)
    {
        products.Remove(product);
    }

    public void ClearCart()
    {
        products.Clear();
    }

    public decimal CalculateTotal()
    {
        decimal total = 0;
        foreach (var product in products)
        {
            total += product.Price;
        }
        return total;
    }
}

Product Class

The Product class represents a product with a name and price. It simply holds the information about a specific product.

• string Name: Property to get or set the name of the product.
• decimal Price: Property to get or set the price of the product.

public class Product
{
    public string Name { get; set; }
    public decimal Price { get; set; }
}

Implementing the ShoppingCart Class

Now that we’ve outlined our classes let’s dive into the implementation of the ShoppingCart class.

This class will serve as the backbone of our shopping cart application, handling all operations related to managing products.

ShoppingCart Class Implementation Details

The ShoppingCart class is responsible for managing the list of products added to the cart. Let’s take a closer look at its implementation:

• List of Products: The products variable is a private member of the ShoppingCart class, representing the list of products in the cart.
• AddProduct Method: This method allows users to add a product to the shopping cart. It takes a Product object as a parameter and adds it to the products list.
• RemoveProduct Method: Users can remove a product from the shopping cart using this method. It also takes a Product object as a parameter and removes it from the products list.
• ClearCart Method: If a user wants to start afresh, they can use this method to clear the shopping cart by removing all products from the products list.
• CalculateTotal Method: This method calculates the total price of all products in the shopping cart. It iterates over the products list and accumulates the price of each product, returning the calculated total as a decimal value.

Implementing the Product Class

Next up, let’s implement the Product class, which represents individual products in our shopping cart.

Product Class

The Product class is straightforward, holding basic information about a product:

• Name Property: This property gets or sets the name of the product.
• Price Property: This property gets or sets the price of the product.

Testing the Shopping Cart Application 🧪

Now that we’ve implemented our shopping cart classes let’s put them to the test! We’ll create a simple console application to demonstrate how the shopping cart works.

Main Method Testing the Application

In the Main method, we’ll create an instance of the ShoppingCart class, add sample products to the cart, perform operations like calculating the total price, removing a product, and clearing the cart.

public class Program
{
    public static void Main(string[] args)
    {
        // Create a new shopping cart
        ShoppingCart cart = new ShoppingCart();

        // Create some sample products
        Product product1 = new Product { Name = "Product 1", Price = 10.99m };
        Product product2 = new Product { Name = "Product 2", Price = 5.99m };
        Product product3 = new Product { Name = "Product 3", Price = 7.99m };

        // Add products to the cart
        cart.AddProduct(product1);
        cart.AddProduct(product2);
        cart.AddProduct(product3);

        // Calculate and print the total
        decimal total = cart.CalculateTotal();
        Console.WriteLine("Total: $" + total);

        // Remove a product from the cart
        cart.RemoveProduct(product2);

        // Calculate and print the updated total
        total = cart.CalculateTotal();
        Console.WriteLine("Updated Total: $" + total);

        // Clear the cart
        cart.ClearCart();
        Console.WriteLine("Cart cleared. Total: $" + cart.CalculateTotal());
    }
}

Product Information Table

When building a shopping cart application, it’s essential to display product information clearly for the users. Let’s create a table to showcase the details of each product added to the cart, including their names and prices.

This table gives users a quick overview of the products they’ve added to their cart, making it easier for them to review their selections before making a purchase.

Feel free to customize this table further based on your application’s requirements. You can add more columns, such as quantity or product description, to provide additional information to your users. Remember, the goal is to create a user-friendly shopping experience that makes it easy for customers to browse, select, and purchase products.
