How to access a model to home view index.cshtml file in ASP.NET Core 5 MVC?

Question

I am completely new to ASP.NET Core and following along the Microsoft's documentation and developing a simple web application. Sorry, if the question is not clear.

I have created a model, view and controller called Broadcast. This model has a field called live. I would like to access this model to home view's index.cshtml file which is a separate view.

I have tried including Broadcast view on the top at index.cshtml file home view

@model IEnumerable<SideCar.Models.Broadcast>

When I am accessing the model using @foreach I get the following error:

System.NullReferenceException: 'Object reference not set to an instance of an object.'

Could you please guide, what should I learn to access the model into a different view? Thank you.

Here is the controller:

using Microsoft.AspNetCore.Mvc;
using SideCar.Data;
using SideCar.Models;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;

namespace SideCar.Controllers
{
    public class BroadcastController : Controller
    {
        private readonly ApplicationDbContext _db;

        public BroadcastController(ApplicationDbContext db)
        {
            _db = db;
        }

        public IActionResult Index()
        {
            IEnumerable<Broadcast> objList = _db.Boradcast;
            return View(objList);
        }
    }
}

and model:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.ComponentModel.DataAnnotations;
using System.Linq;
using System.Threading.Tasks;

namespace SideCar.Models
{
    public class Broadcast
    {
        [Key]
        public int Id { get; set; }
        public string BroadcastHeading { get; set; }        
        public string BroadcastDesc1 { get; set; }
        public string BroadcastDesc2 { get; set; }
        public DateTime ActiveDate { get; set; }
        public DateTime ExpiryDate { get; set; }        
        public string Live { get; set; }
    }
}

Change you index action to this:

public IActionResult Index()
        {
            var objList = _db.Set<Broadcast>().ToArray();
            return View(objList);
        }
