  • 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:

    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>
    27 /// http-equiv="Content-Type" content="text/html; charset=utf-8"
    28 /// </summary>
    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 /// <summary>
    42 /// script src="/script/common.js" type="text/javascript"
    43 /// </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>
