asp.net core multi select เราสามารถส่งค่าเป็น List<Model> ได้ไหมครับ

public ActionResult Create(GlobalModel GlobalModel)
        {
            try
            {
                using (OracleConnection conn = new OracleConnection(_connectionString))
                {
                    conn.Open();
                    string vSql = " ";
                    foreach (var item in GlobalModel.user)
                    {
                        string[] val = item.Split("^");
                        vSql += " INSERT INTO USER(USERID, USERNAME ) VALUES('" + val[0] + "','" + val[1] + "'); ";
                    }

                    OracleCommand cmd = new OracleCommand();
                    using (cmd = new OracleCommand(vSql, conn))
                        cmd.ExecuteNonQuery();
                }
                return RedirectToAction(nameof(Index));
            }
            catch (Exception ex)
            {
                    throw ex;
            }//end try
        }

    public class GlobalModel
    {
        public List<USER> user { get; set; }
        public IEnumerable<USER> Luser { get; set; }
    }

    public class USER
    {
        public string USERID { get; set; }
        public string USERNAME { get; set; }
    }
