C#学习笔记（6）-序列化与反序列化

序列化

就是将对象转换为二进制

反序列化

就是将二进制转换为对象

作用

传输数据。数据在网络中是以二进制形式传输的。
序列化的类不能被继承

关键字

• [Serializable]：定义一个类可被序列化

 [Serializable]

    public class Person
    {
        private string _name;
        private int _age;
        private char _gender;

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

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

        public char Gender
        {
            get { return _gender; }
            set { _gender = value; }
        }

        public void SayHello()
        {
            Console.WriteLine("我是人类");
        }

    }

• 序列化一个类:Serialize

Person p = new _05序列化与反序列化.Person();
p.Name = "张三";
p.Age = 18;
p.Gender = '男';
using (FileStream fsWrite = new FileStream(@"C:\Users\lones\Desktop\新建文本文档.txt",FileMode.OpenOrCreate, FileAccess.Write))
{
    //开始序列化对象
    BinaryFormatter bf = new BinaryFormatter();
    bf.Serialize(fsWrite, p);
}
Console.WriteLine("序列化OK");
Console.ReadKey();

-反序列化一个类：deserialize

Person p;
using (FileStream fsRead = new FileStream(@"C:\Users\lones\Desktop\新建文本文档.txt", FileMode.OpenOrCreate, FileAccess.Read))
{
   BinaryFormatter bfRead = new BinaryFormatter();
   p = (Person)bfRead.Deserialize(fsRead);
}

Console.WriteLine(p.Name);
Console.WriteLine(p.Age);
Console.WriteLine(p.Gender);
Console.ReadKey();
