ASP.NET Core MVC: Database Operations

Performing database operations with ASP.NET Core MVC is very important. In order for the data to interact with users, it is necessary to perform database operations correctly. In this article, I will explain step by step how to perform CRUD operations in an ASP.NET Core MVC project.


// Let's make the necessary adjustments to connect to the database
services.AddDbContext(options =>
    options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));

// Let's define our model classes
public class Product
{
    public int Id { get; set; }
    public string Name { get; set; }
    public decimal Price { get; set; }
}

// Let's create the necessary controller class for database operations
public class ProductController : Controller
{
    private readonly ApplicationDbContext _context;

    public ProductController(ApplicationDbContext context)
    {
        _context = context;
    }

    public IActionResult Index()
    {
        var products = _context.Products.ToList();
        return View(products);
    }

    [HttpPost]
    public IActionResult Create(Product product)
    {
        _context.Products.Add(product);
        _context.SaveChanges();
        return RedirectToAction("Index");
    }

    [HttpPost]
    public IActionResult Edit(Product product)
    {
        _context.Products.Update(product);
        _context.SaveChanges();
        return RedirectToAction("Index");
    }

    [HttpPost]
    public IActionResult Delete(int id)
    {
        var product = _context.Products.Find(id);
        _context.Products.Remove(product);
        _context.SaveChanges();
        return RedirectToAction("Index");
    }
}
