c#的序列化與反序列化

序列化與反序列化

這個可以直接把對象轉化為二進制進行存儲與通信;
在需要序列化的類前加[Serializable]，使用BinaryFormatter類來進行操作;

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

{
    class Program
    {
        static void Main(string[] args)
        {
            Student stu = new Student("劉備",28,'男');
            Student stu2;
            string file = @"E:\code\test\test1.txt";
            using (FileStream fsWriter=new FileStream(file,FileMode.OpenOrCreate,FileAccess.Write))
            {
                //下面對stu進行序列化；
                BinaryFormatter bf = new BinaryFormatter();
                bf.Serialize(fsWriter, stu);
            }
            using (FileStream fsReader=new FileStream(file,FileMode.Open,FileAccess.Read))
            {
                //下面進行反序列話;
                BinaryFormatter bf = new BinaryFormatter();
                stu2 = (Student)bf.Deserialize(fsReader);
            }
            Console.WriteLine("{0}今年{1}歲，是個{2}生",stu2.Name,stu2.Age,stu2.Gender);
            Console.ReadKey();


        }
    }
    [Serializable]
    public class Student
    {
        private string _name;

        public string Name
        {
            get { return _name; }
            set { _name = value; }
        }
        private int _age;

        public int Age
        {
            get { return _age; }
            set { _age = value; }
        }
        private char _gender;

        public char Gender
        {
            get { return _gender; }
            set { _gender = value; }
        }
        public Student(string name,int age,char gender)
        {
            Name = name;
            Age = age;
            Gender = gender;
        }
    }
