C#:淺談使用XML實現序列化

反序 student stat 類型 接口 ML tst In ise

序列化是將一個對象轉換成字節流以達到將其長期保存在內存、數據庫或文件中的處理過程。它的主要目的是保存對象的狀態以便以後需要的時候使用。與其相反的過程叫做反序列化。

序列化一個對象
為了序列化一個對象,我們需要一個被序列化的對象,一個容納被序列化了的對象的(字節)流和一個格式化器。進行序列化之前我們先看看System.Runtime.Serialization名字空間。ISerializable接口允許我們使任何類成為可序列化的類。

如果我們給自己寫的類標識[Serializable]特性,我們就能將這些類序列化。除非類的成員標記了[NonSerializable],序列化會將類中的所有成員都序列化。

序列化的類型

二進制(流)序列化
SOAP序列化(使用IXmlSerializable)
XML序列化
通常大部分都是使用的XML序列化,所以介紹一下使用XML序列化.

Student類

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace XmlSerializers
{
[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 string hoddy;

    public string Hoddy
    {
        get { return hoddy; }
        set { hoddy = value; }
    }

    public Student()
    {
    }

    public Student(string name,int age,string hoddy)
    {
        this.Name = name;
        this.Age = age;
        this.Hoddy = hoddy;
    }

    public void SayHi()
    {
        string mess = string.Format("我是{0},年齡有{1},愛好是{2}", Name, Age, Hoddy);
        Console.WriteLine(mess);
    }

}

}
