In this article I will explain with an example, how to Insert data into SQL Server database using ADO.Net 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.

I have already inserted few records in the table.

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 System.Data.SqlClient;
 
 
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 Action method accepts CustomerModel class object as a parameter.
Inside the Action Method, CustomerId, Name and Country fields are fetched from their respective TextBoxes using CustomerModel class object and passed as parameter to SqlCommand object.
The ExecuteScalar function is executed and the records are inserted into the SQL Server database table using ADO.Net.
Note: For more details on how to use ExecuteScalar function, please refer Understanding SqlCommand ExecuteScalar in C# and VB.Net.
 
public class HomeController : Controller
{
    // GET: Home
    public ActionResult Index()
    {
        return View();
    }
 
    [HttpPost]
    public ActionResult Index(CustomerModel customer)
    {
        string constr = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;
        using (SqlConnection con = new SqlConnection(constr))
        {
            string query = "INSERT INTO Customers(Name, Country) VALUES(@Name, @Country)";
            query += " SELECT SCOPE_IDENTITY()";
            using (SqlCommand cmd = new SqlCommand(query,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
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 a TextBox, DropDownList created using Html.TextBoxFor, HTML.DropDownListFor methods respectively and a Submit Button.
Finally, the Model is checked for NULL and if it is not NULL then, the value of the Model is displayed using JavaScript Alert Message Box.

@{
    Layout = null;
}

            </tr>
            <tr>
                <td>Country: </td>
                <td>
                    @Html.DropDownListFor(m => m.Country, new List<SelectListItem>
                   { new SelectListItem{Text="India", Value="India"},
                     new SelectListItem{Text="China", Value="China"},
                     new SelectListItem{Text="Australia", Value="Australia"},
                     new SelectListItem{Text="France", Value="France"},
                     new SelectListItem{Text="Unites States", Value="Unites States"},
                     new SelectListItem{Text="Russia", Value="Russia"},
                     new SelectListItem{Text="Canada", Value="Canada"}},
                     "Please select")
                </td>
            </tr>
            <tr>
                <td></td>
                <td><input type="submit" value="Submit" /></td>
            </tr>
        </table>
    }
