对象序列化与反序列化

对于要进行序列化操作的对象需要添加[Serializable]声明，例如：

namespace filetest
{
    [Serializable] //必须添加序列化特性
    class User
    {
        public String name;
        public int age;
    }
}

进行序列化操作时需要导入以下两个命名空间：

using System.Runtime.Serialization.Formatters.Binary;
using System.IO;

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

namespace filetest
{
    class Program 
    {
        static void Main(string[] args)
        {
            string file = @"E:vs_workspacefile_testobj.bat";
            ObjDeserialize(file);
        }

        static void ObjSerialize(string file)
        {
            User user = new User();
            user.name = "zhangsan";
            user.age = 25;
            using (Stream output = File.Create(file))
            {
                BinaryFormatter bf = new BinaryFormatter();
                bf.Serialize(output, user);
            }
        }

        static void ObjDeserialize(string file)
        {
            using (Stream input = File.OpenRead(file))
            { 
                BinaryFormatter bf = new BinaryFormatter();
                User user = (User)bf.Deserialize(input);
                Console.WriteLine("User.name:{0}
User.age:{1}", user.name,user.age);
            }
        }
        
    }
}
