生成JSON数据对象

new JObject(
                        new JProperty("total", 33),
                        new JProperty("rows",
                                new JArray(
                //使用LINQ to JSON可直接在select语句中生成JSON数据对象，无须其它转换过程
                                        from p in studentList
                                        select new JObject(
                                                new JProperty("studentID", p.StudentID),
