下面一个json格式图(说一下，json 其实就是js 数组和对象的一种字符串表现形式 var obj=[] 或者var obj={}  )

var json= {} 如下

从图中看 json中有两个成员分别是 total 和 ship(而ship里面有多个对象，那么我们就知道 ship是一个List<ship>列表)

下面我们在C#中模拟输出此效果

public class JsonHelper   {       /// 
       /// JSON序列化       /// 
       public static string JsonSerializer
     
      (T t)       {           DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T));           MemoryStream ms = new MemoryStream();           ser.WriteObject(ms, t);           string jsonString = Encoding.UTF8.GetString(ms.ToArray());           ms.Close();           return jsonString;       }       /// 
      
       /// JSON反序列化       /// 
       public static T JsonDeserialize
      
       (string jsonString)       {           DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T));           MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(jsonString));           T obj = (T)ser.ReadObject(ms);           return obj;       }   }
      
     

//上面jsonHelp是帮助类

public class rows    {        public int itemid { get; set; }        public int productid { get; set; }        public string listprice { get; set; }        public string unitcost { get; set; }        public string status { get; set; }        public string attr1 { get; set; }           }    public class Product    {        public int total { get; set; }        public List
     
       ship { get; set; } //列表集对像 属性    }
     

protected void Page_Load(object sender, EventArgs e)        {            Product prt = new Product(); //主对象            rows  r = new rows();                                 List
     
       list_row = new List
      
       (); //列表 list            for (int i = 0; i < 3; i++)            {                r.itemid = i;                r.productid = i;                r.listprice = "ss_" + i;                r.unitcost = "un_" + i;                r.status = "Status" + i;                r.attr1 = "atrr" + i;                list_row.Add(r);                          }            prt.total = 10;            prt.ship = list_row;            Response.Write(JsonHelper.JsonSerializer
       
        (prt)); //序列化输出        }
       
      
     

最后昨到上面输出的json字符串
