How to make Check Box List in ASP.Net MVC

You can also do Using jquery.No need to change any controller or action.It will simply add the selected checkboxes value in the database table's column as a coma separated.Just add the code in the View Page.

 <div class="editor-field">

        @Html.HiddenFor(model => model.hobbies, new { htmlAttributes = new { id = "hobbies" } })
        Hobbies :
        <input type="checkbox" id="r" onchange="getSelected()" value="Reading" />
        Reading
        <input id="w" type="checkbox" value="Writing" onchange="getSelected()" />
        Writing

        <script>
            function getSelected() {
                var sList = "";
                $('input[type=checkbox]').each(function () {
                    if (this.checked) {
                        sList += this.value + ",";

                    }
                });
                $("#hobbies").val(sList);
            }
        </script>
        @Html.ValidationMessageFor(model => model.hobbies)
    </div>

Here's an example of how to do that.

HomeModel.cs

public class HomeModel
{
    public IList<string> SelectedFruits { get; set; }
    public IList<SelectListItem> AvailableFruits { get; set; }

    public HomeModel()
    {
        SelectedFruits = new List<string>();
        AvailableFruits = new List<SelectListItem>();
    }
}

HomeController.cs

public class HomeController : Controller
{
    public ActionResult Index()
    {
        var model = new HomeModel
        {
            AvailableFruits = GetFruits()
        };
        return View(model);
    }

    [HttpPost]
    public ActionResult Index(HomeModel model)
    {
        if (ModelState.IsValid)
        {
            var fruits = string.Join(",", model.SelectedFruits);

            // Save data to database, and redirect to Success page.

            return RedirectToAction("Success");
        }
        model.AvailableFruits = GetFruits();
        return View(model);
    }

    public ActionResult Success()
    {
        return View();
    }

    private IList<SelectListItem> GetFruits()
    {
        return new List<SelectListItem>
        {
            new SelectListItem {Text = "Apple", Value = "Apple"},
            new SelectListItem {Text = "Pear", Value = "Pear"},
            new SelectListItem {Text = "Banana", Value = "Banana"},
            new SelectListItem {Text = "Orange", Value = "Orange"},
        };
    }
}

Index.cshtml

@model DemoMvc.Models.HomeModel
@{
    Layout = null;
}

<!DOCTYPE html>

<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>Index</title>
    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css">
</head>
<body>
    <div class="container">
        @using (Html.BeginForm("Index", "Home"))
        {
            foreach (var item in Model.AvailableFruits)
            {
                <div class="checkbox">
                    <label>
                        <input type="checkbox"
                               name="SelectedFruits"
                               value="@item.Value"
                               @if(Model.SelectedFruits.Contains(item.Value))
                               {
                                   <text> checked </text> 
                               } 
                               /> @item.Text
                        </label>
                    </div>
            }
            <div class="form-group text-center">
                <input type="submit" class="btn btn-primary" value="Submit" />
            </div>
        }
    </div>
</body>
</html>

Which should result in the following within the Post Action:
