In this article I will explain with an example, how to post Array of objects from View to Controller 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.
 
 

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; }
}
 
 

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 displaying multiple records

Inside this Action method, the Generic List collection of Customer object is received as parameter and returned to the view in JSON format.
public class HomeController : Controller
{
    // GET: Home
    public ActionResult Index()
    {
        return View();
    }
 
    public JsonResult GetCustomers(List<Customer> customers)
    {
        return Json(customers);
    }
}
 
 

View

The View consists of HTML Submit Button.
Inside the View, the following jQuery script is inherited:
1. jquery.min.js
 
When the Submit button is clicked, a JSON array is created.
Then, the JSON array is sent to the Controller using jQuery AJAX function.
@{
    Layout = null;
}
 
<!DOCTYPE html>
 
<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>Index</title>
</head>
<body>
    <input type="button"id="btnSubmit" value="Submit" />
    <script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.7.1/jquery.min.js"></script>
    <script type="text/javascript">
        $(function () {
            $("#btnSubmit").click(function () {
                var customers = [
                    {
                        "CustomerId": 1,
                        "Name": "John Hammond",
                        "Country": "United States"
                    },
                    {
                        "CustomerId": 2,
                        "Name": "Mudassar Khan",
                        "Country": "India"
                    },
                    {
                        "CustomerId": 3,
                        "Name": "Suzanne Mathews",
                        "Country": "France"
                    },
                    {
                        "CustomerId": 4,
                        "Name": "Robert Schidner",
                        "Country": "Russia"
                    }
                ];
 
                //Send the JSON array to Controller using AJAX.
                $.ajax({
                    type: "POST",
                    url: "/Home/GetCustomers",
                    data: JSON.stringify(customers),
                    contentType: "application/json; charset=utf-8",
                    dataType: "json",
                    success: function (r) {
 
                    },
                    error: function (response) {
                        alert(response.responseText);
                    }
                });
            });
        });
    </script>
</body>
</html>
