Windows CE /SmartDeviceProject 操作Json数据实现对象序列化和反序列化

来源：互联网发布：软件测试三角形问题编辑：程序博客网时间：2024/05/22 07:00

使用场景：实现Java对象的Json数据在C#中读取，重新封装为C#的对象，数据传递采用webservice方式，所有返回类型为int 、boolean 、String、long 等基础数据类型，避免传输复杂的java List和自定义对象；而String的格式就是熟悉的Json。访问资源下载路径：http://jsoncf.codeplex.com/

1、引用程序包

2、编写实体对象

using System;using System.Linq;using System.Collections.Generic;using System.Text;using CodeBetter.Json;namespace SmartDeviceProjectWtms.Domain{    [SerializeIncludingBase]    class Demo    {        private int _id;        private String _name;        public int id {            get {  return _id; }            set {  _id = value;}        }        public String name {            get {  return _name;}            set { _name = value;}        }        public Demo() {                 }        public Demo(int _id,String _name)        {            id = _id;            name = _name;        }    }}

注：必须引用可序列化注解

3、反序列化封装工具

using System;using System.Linq;using System.Collections.Generic;using System.Text;using System.ComponentModel;using SmartDeviceProjectWtms.Domain;using CodeBetter.Json;namespace SmartDeviceProjectWtms{    class JsonUtil    {        public static string ReplaceSpecialChar(String jsonStr)         {            jsonStr = jsonStr.Replace("\\t", " ");            jsonStr = jsonStr.Replace("null", "\"" + "null" + "\"");            return jsonStr;        }        /************************************************测试例子**********************************/                   /// <summary>        /// 获取Demo属性的封装对象【例子】        /// </summary>        /// <param name="jsonStr">Json对象字符串集合</param>        /// <returns></returns>        public static Demo GetDemoByJsonStr(String jsonStr)        {            Demo demo = Converter.Deserialize<Demo>(jsonStr,"_");            return demo;        }        /// <summary>        /// 获取Demo属性的封装对象【例子】        /// </summary>        /// <param name="jsonStr">Json对象字符串集合</param>        /// <returns></returns>        public static List<Demo> GetDemoListByJsonStr(String jsonStr)        {            List<Demo> list = Converter.Deserialize<List<Demo>>(jsonStr, "_");            return list;        }    }}

注：ReplaceSpecialChar方法是处理Java　javax.util.Date对象和值为空null的Json字符问题。

4、编写反序列测试类

using System;using System.Linq;using System.Collections.Generic;using System.Windows.Forms;using SmartDeviceProjectWtms.Domain;using CodeBetter.Json;namespace SmartDeviceProjectWtms{    class JsonTest    {        /// <summary>        /// 测试【JSON单个对象】反序列化        /// </summary>        public static void TestDemo2()        {            string jsonStr =@"{""id"":1,""name"":""boonya""}";            MessageBox.Show("{}JSon:" + jsonStr);            Demo demo = JsonUtil.GetDemoByJsonStr(jsonStr);            if (demo != null)            {                MessageBox.Show("{}获取Object：" + demo.id + " " + demo.name);            }        }        /// <summary>        /// 测试【JSON对象集合】反序列化        /// </summary>        public static String TestDemo3() {            string jsonStr = @"[{""id"":1,""name"":""boonya""}]";            List<Demo> dList = JsonUtil.GetDemoListByJsonStr(jsonStr);            if (dList != null) {                MessageBox.Show("[]JSon:" + jsonStr);                foreach (Demo demo in dList)                {                    MessageBox.Show("[]获取Object：" + demo.id + " " + demo.name);                }            }            return jsonStr;        }    }}

注：本例只是一个简单的例子，具体Java对象转过来的Json处理可能更为复杂，但处理基本一样。

5、Json包程序序列化和反序列化操作例子

namespace CodeBetter.Json.Test.Console{    using System;    internal class Program    {        private static void Main(string[] args)        {                        string json = Converter.Serialize(new User("name", "password", AccountStatus.Enabled));            Converter.Serialize("out.txt", new int[] { 1, 2, 3, -4 }, "_");            Console.WriteLine(json);            User user = Converter.Deserialize<User>(json, "_");            int[] values = Converter.DeserializeFromFile<int[]>("out.txt", "_");            Console.WriteLine(user.UserName);                        Console.WriteLine("Done. Press enter to exit");            Console.ReadLine();        }    }    public class BaseUser    {        private int _id = 1;    }    [SerializeIncludingBase]    public class User : BaseUser    {        private string _userName;        private string _password;        [NonSerialized]        private readonly Role _role;        private AccountStatus _status;            private Thing _think = new Thing();        public string UserName        {            get { return _userName; }            set { _userName = value; }        }        public string Password        {            get { return _password; }            set { _password = value; }        }        public AccountStatus Status        {            get { return _status; }            set { _status = value; }        }        public Role Role        {            get { return _role; }        }        public Thing Thing        {            get { return new Thing(); }        }        public User(string userName, string password, AccountStatus status)        {            UserName = userName;            Password = password;            Status = status;            _role = new Role(DateTime.Now, "Admin", this);        }        private User()        {        }    }    public class Role    {        public Role(DateTime expires, string name, User user)        {            Expires = expires;            Name = name;            User = user;        }        public DateTime Expires { get; set; }        public string Name { get; set; }        public User User { get; set; }        public Thing Thing        {            get { return new Thing(); }        }    }    public class Thing    {        private string _name = "ABC";        public string Name        {            get { return _name; }            set { _name = value; }        }    }    public enum AccountStatus    {        Enabled = 1,        Disabled = 2,    }}
