Let me attempt...

One way is to to pass in all of your objects as the "model". Ideally use a ViewModel which will contain the list of all properties and then bind that to your view. This is implementation of the MVVM pattern.

Else, since it looks like a light-weight thing that you are trying to do, simply send a selectlist through a viewbag in controller. Such as...

View:

<label for="Team">Team</label>
   @Html.DropDownListFor("SelectedItem", ViewBag.ListOfTeams)

控制器：

Controller:

public ActionResult GetTeams()
{
    ViewBag.ListOfTeams = GetTeam();
    return View();
}
