ViewViewdata.Model; what model does?

ViewData.Model

i know that Viewdata contains the data that has been returned by view via

return view(//data);

but what does this .Model represents ?

Controller:

using Testing_linq.Models;

namespace Testing_linq.Controllers
{
    public class HomeController : Controller
    {
        public ActionResult Index()
        {
            ViewBag.Message = "Welcome to ASP.NET MVC!";
            var DataContext = new RegistrationDataContext();
            var Registration = DataContext.SelectRegistration_sp();

            return View(Registration);
        }

View:

<table>
@foreach(SelectRegistration_spResult reg in (IEnumerable<Object>)ViewData.Model)
{
    <tr>
     <td>@reg.userEmail </td>
    </tr>
}
</table>

I'm using LInq to Sql classes in model.

The Model represents whatever dynamic information is required to render the page, and is something you provide to your view. For example, if you were going to create a View that shows a person's First name and Last name, you might come up with the following model:

public sealed class PersonViewModel
{
    public string FirstName {get; set; }
    public string LastName {get; set; }
}

It's preferable to use strongly-typed views, so the first line in your .cshtml file would be:

@model MyNameSpace.PersonViewModel

And when your controller returns the view, you would pass what needs to be rendered in to it:

 public ActionResult Index()
 {
     return View(new PersonViewModel() { FirstName = "Moo", LastName = "Juice" });
 }

ViewData.Model refers to the instance of the PersonViewModel passed in, and is accessed in your view via Model shortcut:

 <body>
     <p>
         Hello @Model.FirstName !!
     </p>
 </body>
