C# ArrayList用BinaryFormatter序列化和反序列化进行文件读写的一个简单例子

using System;
using System.Collections;
using System.Linq;
using System.Text;
using System.IO; //文件读写的IO空间
using System.Runtime.Serialization.Formatters.Binary;  //BinaryFormatter序列化需要的空间

 

//Person类

namespace Serializable
{
    [Serializable] //可序列化的声明，一定要有，不然无法序列化
    class Person
    {
        private String name;
        private String sex;
        private int age;

        public Person(String n, String s, int a)
        {
            name = n;
            sex = s;
            age = a;
        }

        public String Name
        {
            get
            {
                return name;
            }
            set
            {
                name = value;
            }
        }

        public String Sex
        {
            get
            {
                return sex;
            }
            set
            {
                sex = value;
            }
        }

        public int Age
        {
            get
            {
                return age;
            }
            set
            {
                age = value;
            }
        }
    }
}

 

//主运行程序

namespace Serializable
{
    class Program
    {
        static void Main(string[] args)
        {
            Person p1 = new Person("张三", "男", 20);
            Person p2 = new Person("John", "男", 20);
            ArrayList al = new ArrayList();
            al.Add(p1);
            al.Add(p2);

            //序列化
            try
            {
                FileStream fs = new FileStream("serialiable.bin", FileMode.Create);
                BinaryFormatter bf = new BinaryFormatter();
                bf.Serialize(fs, al);
                fs.Close();
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }

            Console.WriteLine("序列化成功！");

            Console.Read();

            //反序列化
            try
            {
                FileStream fs = new FileStream("serialiable.bin", FileMode.Open, FileAccess.Read);
                BinaryFormatter bf = new BinaryFormatter();
                ArrayList all = (ArrayList)bf.Deserialize(fs);
                foreach (Person p in all)
                {
                    Console.WriteLine(p.Name + p.Sex + p.Age);
                }
            }
            catch (Exception e)
            {
                Console.WriteLine(e.Message);
            }

            Console.Read();
            Console.Read();
        }
    }
}

 

运行结果：
