1.1 XML序列化/反序列化

using System;
using System.Collections.Generic;
using System.IO;
using System.Xml.Serialization;

namespace XMLSerialize
{
    public class UserInfo
    {
        public int Id;
        public string UserName;
        public string UserPass;
        public string Email;
        public DateTime RegTime;
    }
    class Program
    {
        private static List<UserInfo> list = new List<UserInfo>()
        {
            new UserInfo()
            {Id = 1,UserName = "Kyle",UserPass = "FDASDFAS",Email = "zhangsan@163.com",RegTime = DateTime.Now},
            new UserInfo()
            {Id = 2,UserName = "Bob",UserPass = "FDASDFAS",Email = "lisi@163.com",RegTime = DateTime.Now},
            new UserInfo()
            {Id = 3,UserName = "Lily",UserPass = "FDASDFAS",Email = "wangwu@163.com",RegTime = DateTime.Now},
            new UserInfo()
            {Id = 4,UserName = "John",UserPass = "FDASDFAS",Email = "zhaoliu@163.com",RegTime = DateTime.Now},
            new UserInfo()
            {Id = 5,UserName = "David",UserPass = "FDASDFAS",Email = "tianqi@163.com",RegTime = DateTime.Now},
            new UserInfo()
            {Id = 6,UserName = "Nancy",UserPass = "FDASDFAS",Email = "wangba@163.com",RegTime = DateTime.Now}
        };
        static void Main(string[] args)
        {
            //序列化对象生成文件
            WriteSingleXml();
            //反序列化文件生成对象
            ReadListXml();
            Console.ReadKey();
        }
        private static void WriteSingleXml()
        {
            //序列化集合为xml文件
            Console.WriteLine("collection to xml");
            var reader = new XmlSerializer(typeof(List<UserInfo>));
            //写入文件
            using (var fs = File.OpenWrite(@"D:\UserInfo.xml"))
            {
                reader.Serialize(fs, list);
            }
            Console.WriteLine("write in succeed");
        }
        private static void ReadListXml()
        {
            //反序列化文件
            Console.WriteLine("xml to collection");
            var reader = new XmlSerializer(typeof(List<UserInfo>));
            using (var fs = File.OpenRead(@"D:\UserInfo.xml"))
            {
                var result = reader.Deserialize(fs) as List<UserInfo>;
                foreach (var r in result)
                {
                    Console.WriteLine(r.Email);
                }
                //result.ForEach(Console.WriteLine);
            }
            Console.WriteLine("deserialize succeed");
        }
    }
}

output

2.Json

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Runtime.Serialization;

namespace JsonSerializerAndDeSerializer
{
    [DataContract] // 使用DataContractJsonSerializer必需
   public class Student
    {
        [DataMember]
       public int ID { get; set; }

        [DataMember]
       public string Name { get; set; }

        [DataMember]
       public int Age { get; set; }

        [DataMember]
       public string Sex { get; set; }
    }
}

2.1 DataContractJsonSerializer

using System.Runtime.Serialization.Json;

Student stu = new Student()
 {
     ID = 1,
     Name = "kyle",
     Sex = "male",
     Age = 23
 };
//序列化
DataContractJsonSerializer js = new DataContractJsonSerializer(typeof(Student));
MemoryStream msObj = new MemoryStream();
//将序列化之后的Json格式数据写入流中
js.WriteObject(msObj, stu);
msObj.Position = 0;
//从0这个位置开始读取流中的数据
StreamReader sr = new StreamReader(msObj, Encoding.UTF8);
string json = sr.ReadToEnd();
sr.Close();
msObj.Close();
Console.WriteLine(json);

//反序列化
string toDes = json;
//string to = "{\"ID\":\"1\",\"Name\":\"kyle\",\"Sex\":\"male\",\"Age\":\"1230\"}";
using (var ms = new MemoryStream(Encoding.Unicode.GetBytes(toDes)))
{
    DataContractJsonSerializer deseralizer = new DataContractJsonSerializer(typeof(Student));
    Student model = (Student)deseralizer.ReadObject(ms);// //反序列化ReadObject
    Console.WriteLine("ID=" + model.ID);
    Console.WriteLine("Name=" + model.Name);
    Console.WriteLine("Age=" + model.Age);
    Console.WriteLine("Sex=" + model.Sex);
}
Console.ReadKey(); 

2.2 JavaScriptSerializer

using System.Web.Script.Serialization;

Student stu = new Student()
   {
       ID = 1,
       Name = "Bob",
       Age = 18,
       Sex = "male"
   };

JavaScriptSerializer js = new JavaScriptSerializer();
string jsonData = js.Serialize(stu);//序列化
Console.WriteLine(jsonData);


////反序列化方式一：
string desJson = jsonData;
Student model = js.Deserialize<Student>(desJson);// 反序列化
string message = string.Format("ID={0},Name={1},Age={2},Sex={3}", model.ID, model.Name, model.Age, model.Sex);
Console.WriteLine(message);
Console.ReadKey(); 


////反序列化方式2
dynamic modelDy = js.Deserialize<dynamic>(desJson); //反序列化
string messageDy = string.Format("动态的反序列化,ID={0},Name={1},Age={2},Sex={3}",
    modelDy["ID"], modelDy["Name"], modelDy["Age"], modelDy["Sex"]);//这里要使用索引取值，不能使用对象.属性
Console.WriteLine(messageDy);
Console.ReadKey(); 

2.3 JSON.NET包

首先安装newtonsoft.JSON或在Visual Studio中，工具菜单->管理NuGet包->搜索JSON.NET包

using Newtonsoft.Json;

List<Student> lstStuModel = new List<Student>() 
{

new Student(){ID=1,Name="A",Age=250,Sex="male"},
new Student(){ID=2,Name="B",Age=300,Sex="female"}
};

//Json.NET序列化
string jsonData = JsonConvert.SerializeObject(lstStuModel);

Console.WriteLine(jsonData);
Console.ReadKey();


//Json.NET反序列化
string json = @"{ 'Name':'C#','Age':'3000','ID':'1','Sex':'女'}";
Student descJsonStu = JsonConvert.DeserializeObject<Student>(json);//反序列化
Console.WriteLine(string.Format("反序列化： ID={0},Name={1},Sex={2},Sex={3}", descJsonStu.ID, descJsonStu.Name, descJsonStu.Age, descJsonStu.Sex));
Console.ReadKey();
