ashx c# 输出多个json 数组

  connection = new MySqlConnection(connectionString);

                MySqlCommand myCommand = new MySqlCommand();

                myCommand.Connection = connection;

                myCommand.CommandType = System.Data.CommandType.Text;

                string sql = "select DISTINCT package_category from all_shop where shopname =?shopname and package_category !=''";

                myCommand.CommandText = sql;

                myCommand.Parameters.Add(new MySqlParameter("shopname", MySqlDbType.VarChar, 255)).Value = shopname;

                MySqlDataReader myReader = null;

                connection.Open();

                myReader = myCommand.ExecuteReader();



                System.Collections.ArrayList people = new System.Collections.ArrayList();



                while (myReader.Read())

                {

                    Person p1 = new Person();

                    p1.package_category = myReader["package_category"].ToString();

                    people.Add(p1);

                }



                connection.Close();

                Person[] ps = (Person[])people.ToArray(typeof(Person));

                context.Response.ContentType = "text/plain";

                System.Web.Script.Serialization.JavaScriptSerializer jss = new System.Web.Script.Serialization.JavaScriptSerializer();

                string json = jss.Serialize(ps);//json 

                context.Response.Write(json);

想输出2个数组(sql select 不一样) , 但目前只会写一个的，愿好心人帮帮忙，给个简单例子，教导教导 ！ 感恩！
