【FCL】将实体类序列化为xml，Json等格式

这里有本博客涉及到的序列化Json和Binary格式数据的Demo：点击打开链接

一、序列化成二进制格式

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Formatters.Binary;

namespace BinarySerialization
{
    class Program
    {
        static void Main(string[] args)
        {
            Person p = new Person()
            {
                Name = "Jhon",Age = 11
            };
            Person p2 = null;

            using (Stream objStream = new MemoryStream())
            {
                IFormatter formatter = new BinaryFormatter();
                //序列化
                formatter.Serialize(objStream,p);
                
                StreamReader sr = new StreamReader(objStream);
                Console.WriteLine(sr.ReadToEnd());

                //反序列化
                objStream.Seek(0,SeekOrigin.Begin);
                p2 = formatter.Deserialize(objStream) as Person;
            }

            Console.WriteLine("p2.Name={0},p2.Age={1}",p2.Name,p2.Age);
        }
    }

    [Serializable]
    class Person
    {
        public string Name { get; set; }
        public int Age { get; set; }
    }
}

三、WCF-基于数据契约实体类的序列化

1、序列化为Json格式的数据：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Json;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            Person p = new Person();
            p.Name = "John";
            p.Age = 42;

            MemoryStream stream1 = new MemoryStream();

            DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(Person));
            ser.WriteObject(stream1,p);

            //显示Json格式数据
            stream1.Position = 0;
            StreamReader sr = new StreamReader(stream1);
            Console.WriteLine("Json from of Person object: ");
            Console.WriteLine(sr.ReadToEnd());

            //反序列化
            stream1.Position = 0;
            Person p2 = (Person)ser.ReadObject(stream1);

            Console.WriteLine("p2.Name={0},p2.Age.ToString());
        }
    }     
    //必须加如下特性，否则不能序列化
    [DataContract]
    class Person
    {
        [DataMember]
        public string Name { get; set; }

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