MVC DropDownList Example with SelectList class

Create ASP.NET MVC Framework 4.7.2 based application.

Step1. Create Models/Book

namespace MVCDropdown1.Models
{
    public class Book
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public int Price { get; set; }
        public string Author { get; set; }
    }
}

Step2. Create Controllers/HomeController

using MVCDropdown1.Models;
using System.Collections.Generic;
using System.Web.Mvc;

namespace MVCDropdown1.Controllers
{
    public class HomeController : Controller
    {
        public ActionResult Index()
        {
            List list = new List();
            Book b1 = new Book() { Id = 1, Name = "Java Fundamentals", Price = 200, Author = "Mark" };
            Book b2 = new Book() { Id = 2, Name = "Economics for Beginners", Price = 200, Author = "Bhim Mehta" };
            Book b3 = new Book() { Id = 3, Name = "Physics Fundamentals", Price = 456, Author = "N.C. Roy" };
            Book b4 = new Book() { Id = 4, Name = "C++ Fundamentals", Price = 789, Author = "Robins" };
            //Add books to List
            list.Add(b1);
            list.Add(b2);
            list.Add(b3);
            list.Add(b4);
            //Create SelectList object
            ViewBag.authors = new SelectList(list, "Id", "Author");
            return View();
        }
    }
}

Step3. Create  Views/Home/View

<h2>Index</h2>
@Html.DropDownList("dd", ViewBag.authors as SelectList, new { onchange = "" })

Output
