Copy one Generic List collection to another using C#

Hi!

How I can get list element from list first method and use it from second method list.

        public List<string> Get_Application(string app_id)
        {
            List<string> applicationList = new List<string>();
            OracleCommand cmd = new OracleCommand();
            OracleConnection cn = new OracleConnection(oracleConnection);
            try
            {
                cn.Open();
                OracleDataAdapter da = new OracleDataAdapter();
                cmd.Connection = cn;
                cmd.CommandText = "GET_APPL_INFO";
                cmd.CommandType = CommandType.StoredProcedure;
                cmd.Parameters.Add("app_id", OracleDbType.Varchar2).Value = app_id;
                cmd.Parameters.Add("c_cur", OracleDbType.RefCursor).Direction = ParameterDirection.Output;
                da.SelectCommand = cmd;
                DataTable dt = new DataTable();
                da.Fill(dt);
                foreach (DataRow dr in dt.Rows)
                {
                     applicationList.Add(dr[0].ToString());
                     applicationList.Add(dr[1].ToString());
                     applicationList.Add(RequestPercentDinamic(Convert.ToInt32(app_id)).ToString());
                     applicationList.Add(dr[3].ToString());
                     applicationList.Add(dr[4].ToString());
                     applicationList.Add(dr[5].ToString());
                     applicationList.Add(dr[6].ToString());
                     applicationList.Add(dr[7].ToString());
                     applicationList.Add(dr[8].ToString());
                     applicationList.Add(dr[9].ToString());
                }                
            }
            catch (Exception ex) { }
            finally
            {
                cn.Close();
                cmd.Dispose();
            }
            return applicationList;
        }

In seond method I can't get.

        public async Task<ActionResult>  sendToZipl(int app)
        {
            if (app > 0)
            {
                string appId = app.ToString();

               
                DeclAgroController decController = new DeclAgroController();
                var applicationList = decController.Get_Application(appId);

                ZyplViewModel data = new ZyplViewModel();
                foreach(var appl in applicationList)
                {
                    data.age = appl.age
                };
	   }

            return null;
        }

 The result I want like below:

                foreach(var appl in applicationList)
                {
                    data.age = appl.age
		    data.gender = appl.gender
		    data.sector = appl.sector
                };
