In this article I will explain with an example, how to insert data into database with Stored Procedure using Dapper library in ASP.Net MVC.
 
 

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.

Stored Procedure

The following Stored Procedure will be used to Insert data into the SQL Server database table.
This Stored Procedure accepts Name and Country parameters, which are used to Insert the record in Customers Table.
CREATE PROCEDURE [Customers_InsertCustomer]
      @Name VARCHAR(100),
      @Country VARCHAR(50)
AS
BEGIN
    INSERT INTO [Customers]
               ([Name]
               ,[Country])
    VALUES
               (@Name
               ,@Country)
 
    SELECT SCOPE_IDENTITY()
END
 
 

Model

The Model class consists of following properties.
public class Customer
{
    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;
using System.Configuration;
 
 

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 Customer class object as a parameter.
Inside this Action method, the ExecuteScalar method of Dapper library is used to insert the record into Customers Table using Stored Procedure.
Note: For more details on ExecuteScalar method, please refer my article Understanding Dapper ExecuteScalar in C# and VB.Net.
 
Finally, the CustomerId of the inserted record is set and the Customer class object is returned to the View.
public class HomeController : Controller
{
    // GET: Home
    public ActionResult Index()
    {
        return View();
    }
 
    [HttpPost]
    public ActionResult Index(Customer customer)
    {
        string constr = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;
        string spName = "Customers_InsertCustomer";
        using (SqlConnection con = new SqlConnection(constr))
        {
            object model = new
            {
                Name = customer.Name,
                Country = customer.Country
            };
            customer.CustomerId = Convert.ToInt32(con.ExecuteScalar(spName, model, commandType: CommandType.StoredProcedure));
        }
        return View(model);
    }
}
 
 

View

Inside the View, in the very first line the Customer 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 jQuery script file is inherited:
1. jquery.min.js
 
Then, the Model is checked for NULL and if it is not NULL then, the value of the CustomerId is displayed using JavaScript Alert Message Box.
@model Dapper_Insert_SP_MVC.Models.Customer
@{
    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>
