序列化

就是將物件轉換為二進位制

反序列化

就是將二進位制轉換為物件

作用

傳輸資料。資料在網路中是以二進位制形式傳輸的。
序列化的類不能被繼承

關鍵字

• [Serializable]：定義一個類可被序列化

 [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("我是人類");
        }

    }

• 序列化一個類:Serialize

Person p = new _05序列化與反序列化.Person();
p.Name = "張三";
p.Age = 18;
p.Gender = '男';
using (FileStream fsWrite = new FileStream(@"C:\Users\lones\Desktop\新建文字文件.txt",FileMode.OpenOrCreate, FileAccess.Write
 
))
{
    //開始序列化物件
    BinaryFormatter bf = new BinaryFormatter();
    bf.Serialize(fsWrite, p);
}
Console.WriteLine("序列化OK");
Console.ReadKey();

-反序列化一個類：deserialize

Person p;
using (FileStream fsRead = new FileStream(@"C:\Users\lones\Desktop\新建文字文件.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();
