There a great answers already but Here is another approach.

You will use user as a model, ListUserViewModel as view-model and UserController as the contoller. The work of view-model is to carry all info needed to be displayed on the page from the controller without adding unwanted properties into the model class. In your case list of users from database into the drop down list.

Model:

public class User     //By the way use singular when naming a class
{
    public string name {get; set;}
    public int user_id {get; set;}
}

View-model

public class ListUserViewModel
{
    public list Users{get; set;}
}

Controller

public class UserController : Controller
{
    private DataBaseContext db = new DataBaseContext();

    [HttpGet]
    public ActionResult ListUser()
    {
        var users = db.Users.ToList();

        var viewModel = new ListUserViewModel { Users = users };

        return View(viewModel);
    }
}

Now use ListUserViewModel instead of User in your view as a model

@model Community.Models.ListUserViewModel

and the drop down

@Html.DropDownListFor(m => m.Users, new SelectList(Model.Users, "user_id", "name"), " ")

Explanation:

You are creating drop down list for Users with Model.Users as select list data source. "user_id" as a value of the selected user and "name" as display label. the last argument( i put empty string " ") is a default value that the drop down will display before selection.

I hope this will help you or someone else.
