类、变量常用头：

[XmlRootAttribute]：对根节点的描述，在类声明中使用　如：下例的Html类

[XmlType]:对节点描述，在类声明中使用　　　　　如：下例的Head类

[XmlElement]:节点下内部节点描述，如果对数组标识，是对数组单元描述如：下例的Html.body,Head.title,Head.metas和Head.scripts数组...

[XmlAttribute]：节点下内部属性描述如：下例的Meat.httpequiv,Meat.content,Script.src,Script.type,...

[XmlArrayItem]：数组单元项描述如：下例的Body.lis

[XmlArray]：数组描述如：下例的Body.lis

[XmlIgnore]:使该项不序列化　　　　　　　　　　　　　如：下例的Meta.data

[XmlText]:做为节点的text文本输出　　　　　　　　　　如：下例的Script.content,Li.Content...

例如：

类定义代码

 1 using System;
 2 using System.Xml.Serialization;
 3 
 4  [XmlRootAttribute("html")]
 5     public class Html
 6     {
 7         public Head head { get; set; }
 8 
 9         [XmlElement("body")]
10         public Body body { get; set; }
11     }
12 
13     [XmlType("head")]
14     public class Head
15     {
16         [XmlElement("title")]
17         public string titile;
18 
19         [XmlElement("meta")]
20         public Meta[] metas;
21 
22         [XmlElement("script")]
23         public Script[] scripts;
24     }
25    
26     /// <summary>

32         public string httpEquiv;
33         
34         [XmlAttribute]
35         public string content;
36 
37         [XmlIgnore]
38         public string  data;
39     }
40 
41     /// <summary>

44     public class Script
45     {
46         [XmlAttribute]
47         public string src;
48         [XmlAttribute]
49         public string type;
50 
51         [XmlText]
52         public string content;
53     }
54 
55     public class Body
56     { 
57         [XmlElement("table")]
58         public List<Table> tables=new List<Table>();
59 
60         [XmlArray("ui")]
61         [XmlArrayItem("li")]
62         public List<Li> Lis = new List<Li>();
63     }
64 
65     public class Li
66     {
67         [XmlText]
68         public string content;
69     }
70 
71     public class Table
72     {
73         [XmlAttribute]
74         public string height;
75         [XmlAttribute]
76         public string width;
77 
78         [XmlText]
79         public string content;
80     }

序列化

 1  System.Xml.Serialization.XmlSerializer serializer = new System.Xml.Serialization.XmlSerializer(typeof(Html));
 2             Html html = new Html();
 3             Head head = new Head();
 4             head.title = "这是一个示例";
 5             Meta[] metaArray = new Meta[1];
 6             metaArray[0] = new Meta() { httpEquiv = "Content-Type", content = "text/html; charset=utf-8", data="该数据不被序列化" };
 7             Script[] scriptArray = new Script[2];
 8             scriptArray[0] = new Script() { type = "text/javascript", src = "/script/jquery.js" };
 9             scriptArray[1] = new Script() { type = "text/javascript", content = "var number=6; alert('这是一个示例number='+number);" };
10             head.metas = metaArray;
11             head.scripts = scriptArray;
12             Body body = new Body();
13             body.tables.Add(new Table() { height = "5", width = "4", content = "这是table1" });
14             body.tables.Add(new Table() { content = "这是table2" });
15             body.Lis.Add(new Li() { content = "li1" });
16             body.Lis.Add(new Li() { content = "li2" });
17             html.head = head;
18             html.body = body;
19             string serializerString = "";
20             using (System.IO.MemoryStream stream = new System.IO.MemoryStream())
21             {
22                 System.IO.TextWriter writer = new System.IO.StreamWriter(stream, Encoding.UTF8);
23                 System.Xml.Serialization.XmlSerializerNamespaces ns = new System.Xml.Serialization.XmlSerializerNamespaces();
24                 ns.Add("", "");//不输出xmlns
25                 serializer.Serialize(writer, html, ns);
26                 stream.Position = 0;
27                 byte[] buf = new byte[stream.Length];
28                 stream.Read(buf, 0, buf.Length);
29               serializerString= System.Text.Encoding.UTF8.GetString(buf);
30             }

serializerString值为：

<?xml version="1.0" encoding="utf-8"?>
<html>
  <head>
    <title>这是一个示例</title>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <script src="/script/jquery.js" type="text/javascript" />
    <script type="text/javascript">var number=6; alert('这是一个示例number='+number);</script>
  </head>
  <body>
    <table height="5" width="4">这是table1</table>
    <table>这是table2</table>
    <ui>
      <li>li1</li>
      <li>li2</li>
    </ui>
  </body>
</html>
