Asp.Net MVC Post List of Objects

ASP.NET MVC allows you to easily post a list of objects from a view to a controller. This can be useful when you need to submit multiple items in a single request. Below is a step-by-step guide with code examples to help you achieve this in a clean and organized manner.

1. Model Definition

Create a Person class to represent the objects you want to post.

// Models/Person.cs
public class Person
    public int Id { get; set; }
    public string Name { get; set; }
    public int Age { get; set; }

2. Controller Setup

Create a controller with two actions: one to render the initial view and another to handle the form submission.

// Controllers/YourController.cs
using System.Collections.Generic;
using System.Web.Mvc;

public class YourController : Controller
    public ActionResult Index()
        List<Person> peopleList = GetPeopleList(); // Replace with your data retrieval logic
        return View(peopleList);

    public ActionResult ProcessPeople(List<Person> people)
        if (ModelState.IsValid)
            // Validations passed, process the list of people
            foreach (var person in people)
                // Save to the database or perform other actions

            return RedirectToAction("Success"); // Redirect to a success page

        // ModelState is not valid, return to the form with errors
        return View("Index", people);

    private List<Person> GetPeopleList()
        // Replace this with your actual data retrieval logic
        List<Person> peopleList = new List<Person>
            new Person { Id = 1, Name = "John Doe", Age = 25 },
            new Person { Id = 2, Name = "Jane Smith", Age = 30 },
            // Add more persons as needed

        return peopleList;

3. View Setup

Create a view (Index.cshtml) to render the form.

<!-- Views/Your/Index.cshtml -->
@model List<Person>

@using (Html.BeginForm("ProcessPeople", "Your", FormMethod.Post))
    for (int i = 0; i < Model.Count; i++)
        @Html.HiddenFor(model => model[i].Id)
            @Html.TextBoxFor(model => model[i].Name)
            @Html.TextBoxFor(model => model[i].Age)
        <br />

    <input type="submit" value="Submit" />

4. Submit the Form

Fill in the details and submit the form. The data should be posted to the ProcessPeople action, where you can process the list as needed.

This step-by-step tutorial should guide you through the process of posting a list of objects in an ASP.NET MVC application. Please adapt the code as per your specific requirements and replace the placeholder logic with your actual data retrieval or processing logic.
