C#序列化和反序列化

序列化

序列化导入命名空间

using System.Runtime.Serialization.Formatters.Binary;

序列化练习 

class Program
    {
        static void Main(string[] args)
        {
           
            Person p = new Person();
            p.Name = "张三";
            p.Age = 18;
            p.Gender = '男';
            string path = @"C:\Users\lari\Desktop\新建文本文档.txt";
            using (FileStream fs = new FileStream(path, FileMode.Open, FileAccess.Write, FileShare.Write))
            {
                BinaryFormatter bf = new BinaryFormatter();
                bf.Serialize(fs, p);
            }

            Console.WriteLine("wanshi");
            Console.ReadKey();
    }
    [Serializable ]//标记可序列化

    public class Person
    {


        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 virtual void Show()//虚方法
        {
            Console.WriteLine("我是人");
        }

    }

反序列化来练习

 Person p;
            string path = @"C:\Users\lari\Desktop\新建文本文档.txt";
            using (FileStream fs = new FileStream(path, FileMode.Open, FileAccess.Read , FileShare.Read ))
            {
                BinaryFormatter bf = new BinaryFormatter();
               p =(Person )bf.Deserialize(fs);
            }
            Console.WriteLine(p.Age );
            Console.WriteLine("wanshi");
            Console.ReadKey();
