Collection(List<>) 在传递给 RedirectToAction() asp.net core (MVC) 时消失

无法将集合转移到索引，它只是消失了，不知道在哪里。如果您尝试使用 iCollection 字段传递 User 类，也会发生同样的事情，所有其他字段（int、string）都可以很好地传递，但集合又是空的。一般来说，如何将整个班级转移到那里？这是什么原因？

进行重定向的操作

[HttpPost]
    public async Task<IActionResult> Index(string Login, string Password)
    {

        //var a = db.Users.Include(p => p.MyElem).Where;
        //string Query = $"SELECT [Id], [Login], [Password] FROM [Papka(praktika)].[dbo].[Users] where Login='{Login}' and Password='{Password}'";
        //System.Linq.IQueryable<User> a = db.Users.FromSql(Query);
        System.Linq.IQueryable<User> a = db.Users.Include(p => p.MyElem).Where(p => p.Login == Login && p.Password==Password);
        int g =await a.Include(p => p.MyElem).CountAsync<User>();
        if (g > 0)
        {
            User t =await a.FirstAsync<User>();
            List<OneElem> r = t.MyElem.ToList();

            return RedirectToAction("Index", "Ocenk", r);
        }else
            return View();

    }

通过重定向接受的操作

public class OcenkController : Controller
{
    public IActionResult Index(List<OneElem> log)
    {
        return View(log);
    }
}

模型用户

public class User
{
    public int Id { get; set; }
    public ICollection<OneElem> MyElem { get; set; }

    [Required(ErrorMessage = "Не указан login")]
    [MinLength(2)] 
    [MaxLength(20)]
    public string Login { get; set; }

    [Remote(action: "Vhod", controller: "Home", ErrorMessage = "Неправильный пароль. Длина пароля должна больше 3 символов.")]
    public string Password { get; set; }


    public User()
    {
        MyElem = new List<OneElem>();
    }
