asp.net 对象数组的Xml序列化代码

数组的Xml序列化需要使用XmlArrayAttribute和XmlArrayItemAttribute；XmlArrayAttribute指定数组元素的Xml节点名，XmlArrayItemAttribute指定数组元素的Xml节点名。

如下代码示例：

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

namespace UseXmlSerialization
{
class Program
{
static void Main(string[] args)
{
//声明一个猫咪对象
var cWhite = new Cat { Color = "White", Speed = 10, Saying = "White or black, so long as the cat can catch mice, it is a good cat" };
var cBlack = new Cat { Color = "Black", Speed = 10, Saying = "White or black, so long as the cat can catch mice, it is a good cat" };

CatCollection cc = new CatCollection { Cats = new Cat[] { cWhite,cBlack} };

//序列化这个对象
XmlSerializer serializer = new XmlSerializer(typeof(CatCollection));

//将对象序列化输出到控制台
serializer.Serialize(Console.Out, cc);

Console.Read();
}
}

[XmlRoot("cats")]
public class CatCollection
{
[XmlArray("items"),XmlArrayItem("item")]
public Cat[] Cats { get; set; }
}

[XmlRoot("cat")]
public class Cat
{
//定义Color属性的序列化为cat节点的属性
[XmlAttribute("color")]
public string Color { get; set; }

//要求不序列化Speed属性
[XmlIgnore]
public int Speed { get; set; }

//设置Saying属性序列化为Xml子元素
[XmlElement("saying")]
public string Saying { get; set; }
}
}

以上代码将输出：

<?xml version="1.0" encoding="gb2312"?>



White or black, so long as the cat can catch mice, it is a good
cat


White or black, so long as the cat can catch mice, it is a good
cat
