In this article I will explain with an example, how to insert data into MySQL database in ASP.Net MVC.
Note: For beginners in ASP.Net MVC, please refer my article ASP.Net MVC Hello World Tutorial with Sample Program example.
 
 

Database

I have made use of the following table Customers with the schema as follows.

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; }
}
 
 

Namespaces

You will need to import the following namespaces.
using System.Configuration;
using MySql.Data.MySqlClient;
 
 

Controller

The Controller consists of following Action methods.

Action method for handling GET operation

Inside this Action method, simply the View is returned.
 

Action method for handling POST operation

This method accepts CustomerModel class object as a parameter.
Inside this Action method, the Name and Country values are inserted into the Customers Table of MySQL database using ExecuteScalar method.
Note: For more details on ExecuteScalar method, please refer my article Understanding ExecuteScalar in MySQL in C# and VB.Net.
 
Finally, the CustomerId of the inserted record is set and the CustomerModel class object is returned to the View.
public class HomeController : Controller
{
    // GET: Home
    public ActionResult Index()
    {
        return View();
    }
 
    [HttpPost]
    public ActionResult Index(CustomerModel customer)
    {
        string constr = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;
        using (MySqlConnection con = new MySqlConnection(constr))
        {
            string sql = "INSERT INTO Customers(Name, Country) VALUES(@Name, @Country);";
            sql += "SELECT LAST_INSERT_ID();";
            using (MySqlCommand cmd = new MySqlCommand(sql, con))
            {
                con.Open();
                cmd.Parameters.AddWithValue("@Name", customer.Name);
                cmd.Parameters.AddWithValue("@Country", customer.Country);
                customer.CustomerId = Convert.ToInt32(cmd.ExecuteScalar());
                con.Close();
            }
        }
        return View(customer);
    }
}
 
 

View

HTML Markup

Inside the View, in the very first line the CustomerModel class is declared as Model for the View.
The View consists of an HTML Form which has been created using the Html.BeginForm method with the following parameters.
ActionName – Name of the Action. In this case the name is Index.
ControllerName – Name of the Controller. In this case the name is Home.
FormMethod – It specifies the Form Method i.e. GET or POST. In this case it will be set to POST.
The View also consists of an HTML Table, which consists of TextBox and DropDownList created using Html.TextBoxFor and HTML.DropDownListFor methods respectively and a Submit Button.
Inside the View, the following script file is inherited:
1. jquery.min.js
 

Submitting the Form

When the Submit button is clicked then, the CustomerModel class object is checked for NULL and if it is not NULL then, the CustomerId is displayed using JavaScript Alert Message Box.
@model Insert_MySQL_MVC.Models.CustomerModel
@{
    Layout = null;
}
 
<!DOCTYPE html>
<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>Index</title>
</head>
<body>
    @using (Html.BeginForm("Index", "Home", FormMethod.Post))
    {
        <table cellpadding="0" cellspacing="0">
            <tr>
                <td>Name: </td>
                <td>
                    @Html.TextBoxFor(m => m.Name)
                </td>
            </tr>
            <tr>
                <td>Country: </td>
                <td>
                    @Html.DropDownListFor(m => m.Country, new List<SelectListItem>
                    {
                      new SelectListItem { Text = "United States", Value = "United States" },
                      new SelectListItem { Text = "India", Value = "India" },
                      new SelectListItem { Text = "France", Value = "France" },
                      new SelectListItem { Text = "Russia", Value = "Russia" }},
                      "Please select")
                </td>
            </tr>
            <tr>
                <td></td>
                <td><input type="submit" value="Submit" /></td>
            </tr>
        </table>
    }
    <script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.7.1/jquery.min.js"></script>
    @if (Model != null)
    {
        <script type="text/javascript">
            $(function () {
                alert("Inserted Customer ID: " + @Model.CustomerId);
            });
        </script>
    }
</body>
</html>
