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     ///  27 /// http-equiv="Content-Type" content="text/html; charset=utf-8" 28 /// 
 29     public class Meta 30     {
   31         [XmlAttribute("http-equiv")] 32         public string httpEquiv; 33         34         [XmlAttribute] 35         public string content; 36 37         [XmlIgnore] 38         public string  data; 39     } 40 41     ///  42 ///  script src="/script/common.js" type="text/javascript" 43 /// 
 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
     
       tables=new List
     
 Lis = new List
     
      (); 59 60         [XmlArray("ui")] 61         [XmlArrayItem("li")] 62         public List
(); 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：
