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

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.

I have already inserted few records in the table.

Stored Procedure

The following Stored Procedure is used to display the records from SQL Server database.
CREATE PROCEDURE [Customers_GetCustomers]
AS
BEGIN
    SET NOCOUNT ON;
    SELECT [CustomerId]
          ,[Name]
          ,[Country]
    FROM [Customers]
END
 
 

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.Data;
using System.Data.SqlClient;
 
 

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 ConnectionStrings section of the AppSettings.json file.
Note: For more details on how to read Connection String from AppSettings.json, please refer my article .Net Core 7: Read Connection String from AppSettings.json file.
 
Then, the name of the Stored Procedure is passed to the Query method of the Dapper library which then returns Generic List collection of CustomerModel class objects.
Finally, the Customer records are returned to the View.
public class HomeController : Controller
{
    public IConfiguration Configuration { get; set; }
 
    public HomeController(IConfiguration _configuration)
    {
        this.Configuration = _configuration;
    }
    public IActionResult Index()
    {
        string spName = "Customers_GetCustomers";
        string constr = this.Configuration.GetSection("ConnectionStrings")["MyConn"];
        using (SqlConnection con = new SqlConnection(constr))
        {
            return View(con.Query<CustomerModel>(spName, commandType: CommandType.StoredProcedure));
        }
    }
}
 
 

View

HTML Markup

Inside the View, in the very first line the Generic List collection of CustomerModel class is declared as Model for the View.
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 Dapper_Select_SP_Core_MVC.Models
@model List<CustomerModel>
@addTagHelper*, Microsoft.AspNetCore.Mvc.TagHelpers
@{
      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>
