XML序列化和反序列化及实例

XmlSerializer.Deserialize 方法 (XmlReader)  反序列化

1.普通xml序列化，不带属性序列化

2.带属性的序列化  SoapAttribute 属性 （本章主要代码）

*****************************************************************************************************

关键1：[SoapAttribute(DataType = "date", AttributeName = "CreationDate")]   //此句告诉编译器 序列化成属性，然后属性name为createiondate

        public DateTime Today;

关键2： 带属性的序列化和反序列化要使用下面的

XmlTypeMapping myMapping = (new SoapReflectionImporter().ImportTypeMapping(typeof(T)));

XmlSerializer mySerializer = new XmlSerializer(myMapping);

*******************************************************************************************************

1.基本类

public class Douban
  {
      public Logininfo Login=new Logininfo();
      public Registinfo Regist=new Registinfo();
  }

  public class Logininfo
  {

     [SoapAttribute(DataType = "string", AttributeName = "CreationDate")]
      public string testValue;

      public  string LoginUrl;
      public  string LoginCodeUrl;
  }
  public class Registinfo
  {
      public  string RegistUrl;
      public  string RegistCodeUrl;
  }

2.序列化的方法

public void XmlSerialize<T>(string filename,T t)
  {
     // Create an instance of the XmlSerializer class.
     XmlTypeMapping myMapping = 
     (new SoapReflectionImporter().ImportTypeMapping(
     typeof(T)));
     XmlSerializer mySerializer =  
     new XmlSerializer(myMapping);
          XmlTextWriter writer = 
     new XmlTextWriter(filename, Encoding.UTF8);
     writer.Formatting = Formatting.Indented;
     writer.WriteStartElement("wrapper");   //词句生成必须有，代表最顶级的元素名称
     // Serialize the class, and close the TextWriter.
     mySerializer.Serialize(writer, t);
     writer.WriteEndElement();
     writer.Close();
  }

3. 使用序列化方法，序列化指定的类

生成douban实例d，并在 Login字段上增加属性CreationDate= wocaonima

            Douban d = new Douban();
            d.Login.testValue = "wocaonima";
            d.Login.LoginUrl = "1";
            d.Login.LoginCodeUrl = "2";
            d.Regist.RegistUrl = "3";
            d.Regist.RegistCodeUrl = "4";


            XmlSerialize<Douban>(@"C:\Users\ipod\Documents\Visual Studio 2010\Projects\douban注册_2013.3.4_DataGridView\datagridvew 实例\datagridvew 实例\ini3.xml", d);

生成的ini3.xml 文件内容如下。

<wrapper>
  <Douban xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" id="id1">
    <Login href="#id2" />
    <Regist href="#id3" />
  </Douban>
  <Logininfo id="id2" d2p1:type="Logininfo" CreationDate="wocaonima" xmlns:d2p1="http://www.w3.org/2001/XMLSchema-instance">
    <LoginUrl xmlns:q1="http://www.w3.org/2001/XMLSchema" d2p1:type="q1:string">1</LoginUrl>
    <LoginCodeUrl xmlns:q2="http://www.w3.org/2001/XMLSchema" d2p1:type="q2:string">2</LoginCodeUrl>
  </Logininfo>
  <Registinfo id="id3" d2p1:type="Registinfo" xmlns:d2p1="http://www.w3.org/2001/XMLSchema-instance">
    <RegistUrl xmlns:q3="http://www.w3.org/2001/XMLSchema" d2p1:type="q3:string">3</RegistUrl>
    <RegistCodeUrl xmlns:q4="http://www.w3.org/2001/XMLSchema" d2p1:type="q4:string">4</RegistCodeUrl>
  </Registinfo>
</wrapper>

最后补充带属性的反序列化方法：

public void DeserializeOriginal<T>(string filename,T t)
   {
      // Create an instance of the XmlSerializer class.
      XmlTypeMapping myMapping = 
      (new SoapReflectionImporter().ImportTypeMapping(
      typeof(T)));
      XmlSerializer mySerializer =  
      new XmlSerializer(myMapping);


      // Reading the file requires an  XmlTextReader.
      XmlTextReader reader= 
      new XmlTextReader(filename);
      reader.ReadStartElement("wrapper");

      // Deserialize and cast the object.
      
      myGroup = (t) mySerializer.Deserialize(reader);
      reader.ReadEndElement();
      reader.Close();

   }
