Problem with Details ID

Here is the Code:

public class DetailsModel : PageModel
    {
        private SignInManager _signInManager;
        private Luser _useR;
        public DetailsModel(
            UserManager userManager,
            SignInManager signInManager,
            RoleManager roleManager,
            ApplicationDbContext contexT

            )
        {
            _signInManager = signInManager;
            _useR = new Luser(userManager, signInManager, roleManager, contexT);
        }
        public void OnGet(int Idc)
        {
            var data = _useR.getTusuariosAsync(null, Idc);
            if(0 < data.Result.Count)
            {
                Input = new InputModel
                {
                    DataUser = data.Result.ToList().Last(),
                };

            }
        }
        [BindProperty]
        public InputModel Input { get; set; }
        public class InputModel
        {
            public InputModelRegistrar DataUser { get; set; }
        }
    }

The problem that I got when I select a User it supose to get the ID and show the information from that user but just get the last user. How can I do to Fix that
