一个关于json的问题，急！

Question

前台一个json数组：
var jsonObj2={persons:[{name:"jordan",sex:"m",age:"40"}, 
{name:"bryant",sex:"m",age:"28"}, 
{name:"McGrady",sex:"m",age:"27"} 
]}; 
到后台保存时我怎么把这个json数组转化为后台的数据
也就是到后台取到这个json数组的值

Answer 1

- -jquery ajax() post 过去

Answer 2

 .net 有直接json操作是转换数据的没? 
 如果没有, 那就优先{persons:[{ 跟最后一个]} 去掉, 
然后使用},{ split 开, 再一个字符串 分隔. 分隔...  这是我的想法..

Answer 3

到网上下这个库：Newtonsoft.Json.dll用法和XML那个操作类差不多，参考如下：
注意：这个是将后台数据转成Json数组，你反过来就是的了！
            //构建JSon对象           
            StringWriter text = new StringWriter();
            JsonWriter json = new JsonWriter(text);
            json.Formatting = Formatting.Indented;
            json.WriteStartArray();
            for (int i = 0; i < data.Tables[0].Rows.Count; i++)
            {
                DataRow currRow = data.Tables[0].Rows[i];
                
                json.WriteStartObject();
                //简历ID
                json.WritePropertyName("rid");
                json.WriteValue(Convert.ToInt32(currRow["id"]));
                //求职者姓名
                PersonalInfo pinfo = new PersonalInfo();
                int mid = Convert.ToInt32(currRow["mid"]);
                DataSet temp = pinfo.QueryPersonalInfoByUid(mid);
                json.WritePropertyName("realName");
                json.WriteValue(temp.Tables[0].Rows[0]["realName"].ToString());
                //求职者ID
                json.WritePropertyName("mid");
                json.WriteValue(mid.ToString());
                //性别
                int str_sex = Convert.ToInt32(temp.Tables[0].Rows[0]["sex"]);
                json.WritePropertyName("sex");
                if (str_sex == 1) json.WriteValue("男");
                else json.WriteValue("女");                    
                //年龄
                DateTime birthday = Convert.ToDateTime(temp.Tables[0].Rows[0]["birthday"]);
                int age = DateTime.Now.Year - birthday.Year;
                json.WritePropertyName("age");
                json.WriteValue(age.ToString());
                //学历
                string str_education = temp.Tables[0].Rows[0]["education"].ToString();
                item = category.QueryCategoryById(str_education);
                json.WritePropertyName("education");
                json.WriteValue(item.Tables[0].Rows[0]["cName"].ToString());
                //行业职位
                string str_workIndustry = currRow["workIndustry"].ToString();
                item = category.QueryCategoryById(str_workIndustry);                
                string industry_job = item.Tables[0].Rows[0]["cName"].ToString() + "-";
                string str_workJob = currRow["workJob"].ToString();
                item = category.QueryCategoryById(str_workJob);
                industry_job += item.Tables[0].Rows[0]["cName"].ToString();
                json.WritePropertyName("job");
                json.WriteValue(industry_job);
                //工作经验
                string str_workAge = currRow["workAge"].ToString();
                item = category.QueryCategoryById(str_workAge);
                json.WritePropertyName("workAge");
                json.WriteValue(item.Tables[0].Rows[0]["cName"].ToString());
                //简历公开程度
                string str_openness = currRow["openness"].ToString();
                item = category.QueryCategoryById(str_openness);
                json.WritePropertyName("openness");
                json.WriteValue(item.Tables[0].Rows[0]["cName"].ToString());                
                                
                json.WriteEndObject();
            }
            json.WriteEndArray();
