asp.net利用对象数组实现xml序列化的代码实例

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; }
    }
}<SPAN style="FONT-FAMILY: verdana, Arial, Helvetica, sans-serif" face="verdana, Arial, Helvetica, sans-serif"><SPAN class=Apple-style-span style="FONT-SIZE: 14px; LINE-HEIGHT: 21px; WHITE-SPACE: normal">
</SPAN></SPAN>

以上代码将输出：

<?xml version="1.0" encoding="gb2312"?>
<cats xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <items>
    <item color="White">
      <saying>White or black,  so long as the cat can catch mice,  it is a good
cat</saying>
    </item>
    <item color="Black">
      <saying>White or black,  so long as the cat can catch mice,  it is a good
cat</saying>
    </item>
  </items>
</cats>
