In this article I will explain with an example, how to select data from MySQL database using Dapper library 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.
 
 

Installing Dapper package using Nuget

In order to install Dapper library using Nuget, please refer my article Install Dapper from Nuget in Visual Studio.
 
 

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 Dapper;
using System.Configuration;
using MySql.Data.MySqlClient;
 
 

Controller

The Controller consists of following Action method.

Action Method for handling GET operation

Inside this Action method, first the connection is read from the Web.Config file.
Note: For more details on how to read connection string from Web.Config file, please refer my article Read or Write Connection Strings in Web.Config file using ASP.Net using C# and VB.Net.
 
Finally, using Query method of Dapper library records are fetched from the Customers Table of the MySQL database.
public class HomeController : Controller
{
    // GET: Home
    public ActionResult Index()
    {
        string constr = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;
        string sql = "SELECT CustomerId, Name, Country FROM Customers";
        using (MySqlConnection con = new MySqlConnection(constr))
        {
            return View(con.Query<CustomerModel>(sql));
        }           
    }
}
 
 

View

HTML Markup

Inside the View, in the very first line the CustomerModel class is declared as IEnumerable which specifies that it will be available as a Collection.
For displaying the records, an HTML Table is used. A FOR EACH loop will be executed over the Model which will generate the HTML Table rows with the Customer records.
@model IEnumerable<CustomerModel>
@using Dapper_Select_MySQL_MVC.Models
@{
    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>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>
