Serialize

SerializableAttribute

当一个类标记为SerializableAttribute 特性时，那么这个类就可以直接调用Serialize和Deserialize 函数进行类数据的序列化和反序列化。例如使用BinaryFormatter进行序列化时，一定要指定类的SerializableAttribute特性，否则运行时会报异常。但是，不是所有的类在序列化或反序列化时都需要SerializableAttribute特性，比如XmlSerializer序列化或反序列化就不需要该特性。

[Serializable]
public class Person
{
    public string Name { get; set; }
    public int Age { get; set; }
}

public static void Main(string[] args)
{
    Person person = new Person { Name = "John Doe", Age = 30 };

    // Serialize the object to a file
    using (FileStream fs = new FileStream("person1.dat", FileMode.Create))
    {
        BinaryFormatter formatter = new BinaryFormatter();
        formatter.Serialize(fs, person);
    }

    // Deserialize the object from the file
    using (FileStream fs = new FileStream("person1.dat", FileMode.Open))
    {
        BinaryFormatter formatter = new BinaryFormatter();
        Person deserializedPerson = (Person)formatter.Deserialize(fs);
        Console.WriteLine($"Name: {deserializedPerson.Name}, Age: {deserializedPerson.Age}");
    }

    // Serialize the object to a file
    using (FileStream fs = new FileStream("person.xml", FileMode.Create))
    {
        XmlSerializer serializer = new XmlSerializer(typeof(Person));
        serializer.Serialize(fs, person);
    }

    // Deserialize the object from the file
    using (FileStream fs = new FileStream("person.xml", FileMode.Open))
    {
        XmlSerializer serializer = new XmlSerializer(typeof(Person));
        Person deserializedPerson = (Person)serializer.Deserialize(fs);
        Console.WriteLine($"Name: {deserializedPerson.Name}, Age: {deserializedPerson.Age}");
    }
    
    Console.ReadKey();
