如何反序列化为对象具体步骤见:[将json带数组的数据反序列化][json]  
将List数据添加到数组中，然后将数组以\[“”,”“\]格式输出：

类似这里的id(多个放到数组中)

public class OrderList
        {
            public bool success { get; set; }
            public List<ModelOrder> model { get; set; }
            public int total { get; set; }
        }
    
     public class ModelOrder
        {
            public string id { get; set; }
            public string code { get; set; }
            public string entityId{ get; set; }
            public string name{ get; set; }
            public string price{ get; set; }
            public int kind { get; set; }
            public string kindName{ get; set; }
        }

public static String test(string jsonStr)
    {
        System.Web.Script.Serialization.JavaScriptSerializer js = new System.Web.Script.Serialization.JavaScriptSerializer();
    
        Test.OrderList orderList = js.Deserialize<Test.OrderList>(jsonStr);
                if(orderList.success)
                {
                    List<Test.ModelOrder> modelOrder = orderList.model;
    
                    //将这个列表中的orderId直接添加到数组中
                    string[] array = new string[modelOrder.Count];//创建数组
                    string resArr="";
                    for (int i=0;i< modelOrder.Count;i++)//以for方式
                    {
                        Test.ModelOrder item = modelOrder[i];//foreach 与for的互转
    
                            String orderIdOrder = item.orderVo.orderId;
                        array[i] = orderIdOrder.ToString();
                        resArr = string.Join("\",\"",  (string[])array.ToArray() ); //\"" + ticket+"\"
                                                                                 //.ToArray(typeof(string)));
    
    
                    }
                    string arrStr = "[\"" + resArr + "\"]";//将数据转为数组["",""]格式输出
                    System.Diagnostics.Debug.WriteLine("订单列表直接toString为：" + array.ToString());
                    System.Console.WriteLine("");
                    System.Console.WriteLine("数组结构为："+ arrStr);
    
                    //foreach的方式为：
                    foreach (Test.ModelOrder item in modelOrder)
                    {
                        String orderIdOrder = item.orderVo.orderId;
                    }
    
    }

运行结果为：
