AJAX从前台序列化传对象

 //点击确定过后构造一个json对象
                    var jsonDBJ = {};
                    //对象名字要与后台对象名字对应
                    jsonDBJ.id = "001";
                    jsonDBJ.Username = "张三";
                    jsonDBJ.Usernum = "NS001";
                    jsonDBJ.Userclass = "一班";
                   //把json转化为字符串
                    var Jsonstr = JSON.stringify(jsonDBJ);
                    //再通过AJAX提交到后台
                       $.ajax({
                            url: "Handler1.ashx",
                            type: "post",
                            //把字符串传递到后台
                            data: { jsonstr: Jsonstr },
                            success: function (result) {
                                //输出结果
                                alert(result)
                            }
                        })

         //先引入命名空间
                using System.Web.Script.Serialization;
                //接收前台传递的字符串
                string jsonstr = context.Request["jsonstr"];
                //反序列化
               JavaScriptSerializer jss = new JavaScriptSerializer();
              //指定转换成的对象
               Provice provice = jss.Deserialize<Provice>(jsonstr);
