In this article I will explain a simple tutorial with an example, how to use MySQL database with MySQL Connector in ASP.Net Core MVC.
Note: For beginners in ASP.Net Core (.Net Core 7), please refer my article ASP.Net Core 7: Hello World Tutorial with Sample Program example.

Namespace

You will need to import the following namespace.
using MySql.Data.MySqlClient;
 
 

Model

The Model class consists of following properties.
public class CustomerModel
{
    public int CustomerId { get; set; }
    public string Name { get; set; }
    public string Country { get; set; }
}
 
 

Controller

The Controller consists of following Action method.

Action method for handling GET operation

Inside this Action method, a Generic List collection of CustomerModel class object is created.
Then, the records are fetched from the Customers table of the MySQL database using DataReader (MySqlDataReader) and set to the Generic List collection of CustomerModel class.
Finally, the Generic List collection of CustomerModel class is returned to the view.
public class HomeController : Controller
{
    public IConfiguration Configuration { get; set; }
 
    public HomeController(IConfiguration _configuration)
    {
        this.Configuration = _configuration;
    }
 
    public IActionResult Index()
    {
        List<CustomerModel> customers = newList<CustomerModel>();
        string sql = "SELECT CustomerId, Name, Country FROM Customers";
        string constr = this.Configuration.GetSection("ConnectionStrings")["MyConn"];
        using (MySqlConnection con = new MySqlConnection(constr))
        {
            using (MySqlCommand cmd = new MySqlCommand(sql, con))
            {
                con.Open();
                using (MySqlDataReader sdr = cmd.ExecuteReader())
                {
                    while (sdr.Read())
                    {
                        customers.Add(new CustomerModel
                        {
                            CustomerId = Convert.ToInt32(sdr["CustomerId"]),
                            Name = sdr["Name"].ToString(),
                            Country = sdr["Country"].ToString()
                        });
                    }
                }
                con.Close();
            }
        }
        return View(customers);
    }
}
 
 

View

HTML Markup

Inside the View, the CustomerModel is declared as IEnumerable which specifies that it will be available as a Collection.
For displaying the records, an HTML Table is used. A FOREACH loop will be executed over the Model which will generate the HTML Table rows with the Customer records.
@using MySql_Core.Models
@modelIEnumerable<CustomerModel>
@{
    Layout = null;
}
 
<!DOCTYPE html>
 
<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>Index</title>
</head>
<body>
    <table cellpadding="0" cellspacing="0">
        <tr>
            <th>Customer Id</th>
            <th>Contact Name</th>
            <th>Country</th>
        </tr>
        @foreach (CustomerModel customer in Model)
        {
            <tr>
                <td>@customer.CustomerId</td>
                <td>@customer.Name</td>
                <td>@customer.Country</td>
            </tr>
        }
    </table>
</body>
</html>
