C# json操作

使用到LitJSON 这个第三方dll，

用到的两个实体类

    class jsonRoot     {        public string numPs { get; set; }        public string qty { get; set; }     }
     class jsonClass     {         public int count { get; set; }         public List<jsonRoot> root { get; set; }     }

下面 json和类之间的互转

        private void obj2Json()        {            jsonClass jc = new jsonClass();            jsonRoot jr = new jsonRoot();             jsonRoot jr2 = new jsonRoot();            List <jsonRoot> ljr =new List<jsonRoot> ();            jr.numPs = "aaaaaaaa";            jr.qty = "111111";            jr2.numPs = "bbbbbbbb";            jr2.qty = "2222222";            ljr.Add (jr); ljr.Add (jr2);            jc.count = 8;            jc.root = ljr;            string js = JsonMapper.ToJson(jc);            Console.WriteLine(js);            //打印出   {"count":8,"root":[{"numPs":"aaaaaaaa","qty":"111111"},{"numPs":"bbbbbbbb","qty":"2222222"}]}        }

json 转obj

        private void json2Obj()        {            string json = "{\"count\":8,\"root\":[{\"numPs\":\"aaaaaaaa\",\"qty\":\"111111\"},{\"numPs\":\"bbbbbbbb\",\"qty\":\"2222222\"}]}";            jsonClass thomas = JsonMapper.ToObject<jsonClass>(json);            List < jsonRoot > ls= thomas.root;            Console.WriteLine("-----", thomas.count);         }
