XML 自定义串行化

      使用XML串行化就可以将类的实例转换为XML,反之亦然。开发人员经常需要进行XML穿行化。
      程序清单中展示了一个串行化的实例。第一步是创建 Person  类的实例,并用进行初始化。然后利用XmlSerializer将Person  类的这个实例串行化。
using  System;
using  System.Data;
using  System.Configuration;
using  System.Web;
using  System.Web.Security;
using  System.Web.UI;
using  System.Web.UI.WebControls;
using  System.Web.UI.WebControls.WebParts;
using  System.Web.UI.HtmlControls;

/// <summary>
/// Person 的摘要说明
/// </summary>

public   class  Person
{
    
public Person()
    
{
        
//
        
// TODO: 在此处添加构造函数逻辑
        
//
    }


    
public string Name
    
{
        
set
        
{
            _name 
= value;
        }

        
get
        
{
            
return _name;
        }

    }
   private string _name;

    
public int Age
    
{
        
set
        
{
            _age 
= value;
        }

        
get
        
{
            
return _age;
        }

    }
   private int _age;
}


<% @ Page Language = " C# "   %>
<% @ Import Namespace = " System.Xml.Serialization "   %>

< script runat = " server " >
    
    
protected   void  Page_Load( object  sender, EventArgs e)
    
{
        Person person 
= new Person();
        person.Name 
= "☆聊ゾ聊☆";
        person.Age 
= 23;
        
//Response.Clear();
        
//Response.ContentType = "text/xml";
        XmlSerializer serializer = new XmlSerializer(person.GetType());
        serializer.Serialize(Response.OutputStream, person);
    }

</ script >
运行后得到的结果:
<? xml version = " 1.0 " ?>
< Person xmlns:xsi = " http://www.w3.org/2001/XMLSchema-instance "  xmlns:xsd = " http://www.w3.org/2001/XMLSchema " >
  
< Name > ☆聊ゾ聊☆ </ Name >
  
< Age > 23 </ Age >
</ Person >

自定义串行化。假设需要把某个类的一个共有属性转换为 XML 属性,那么上面的做法就无法满足要求了。为了达到这一目的,我们可以实现自定义的XML串行化。程序清单如下:
using  System;
using  System.Xml.Serialization;

[XmlRoot(
" 员工 " )]
public   class  Employee
{
    
public Employee()
    
{
    }


    [XmlAttribute(
"姓名")]
    
public string Name
    
{
        
set
        
{
            _name 
= value;
        }

        
get
        
{
            
return _name;
        }

    }
   private string _name;

    [XmlAttribute(
"年龄")]
    
public int Age
    
{
        
set
        
{
            _age 
= value;
        }

        
get
        
{
            
return _age;
        }

    }
   private int _age;

    [XmlElement(
"备注")]
    
public string Remarks
    
{
        
set
        
{
            _remarks 
= value;
        }

        
get
        
{
            
return _remarks;
        }

    }
   private string _remarks;
}


<% @ Page Language = " C# "   %>
<% @ Import Namespace = " System.Xml.Serialization "   %>

< script runat = " server " >
    
    
protected   void  Page_Load( object  sender, EventArgs e)
    
{
        Employee employee 
= new Employee();
        employee.Name 
= "☆聊ゾ聊☆";
        employee.Age 
= 23;
        employee.Remarks 
= "☆聊ゾ聊☆ ☆聊ゾ聊☆ ☆聊ゾ聊☆ ☆聊ゾ聊☆ ☆聊ゾ聊☆";
        
//Response.Clear();
        
//Response.ContentType = "text/xml";
        XmlSerializer serializer = new XmlSerializer(employee.GetType());
        serializer.Serialize(Response.OutputStream, employee);
    }

</ script >

运行结果:
<? xml version = " 1.0 " ?>
< 员工 xmlns:xsi = " http://www.w3.org/2001/XMLSchema-instance "  xmlns:xsd = " http://www.w3.org/2001/XMLSchema "  姓名 = " ☆聊ゾ聊☆ "  年龄 = " 23 " >
  
< 备注 > ☆聊ゾ聊☆ ☆聊ゾ聊☆ ☆聊ゾ聊☆ ☆聊ゾ聊☆ ☆聊ゾ聊☆ </ 备注 >
</ 员工 >
