学习C# XmlSerializer 序列化反序列化XML
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:

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>
