xml 序列化和反序列化

xml 格式如下：

<?xml version="1.0" encoding="utf-8" ?>
<Persons>
<Person Name="张三" Sex="男" Age="18" Height ="180" ></Person>
<Person Name="李四" Sex="男" Age="21" Height ="170" ></Person>
<Person Name="王五" Sex="女" Age="12" Height ="120" ></Person>
<Person Name="赵六" Sex="男" Age="58" Height ="160" >
<Children>
<Child Name="孩子一" Sex="2"></Child>
<Child Name="孩子二" Sex="5"></Child>
</Children>
</Person>
</Persons>

为了方便起见，以下略去读取xml文件以及写入生产xml文件，直接将以上xml文件写在cs文件中。

namespace XML序列化
{

class MyXmlOptions
{
public Persons per { get; set; }
public string xmlString { get; set; }
public MyXmlOptions()
{
//读取本地 xml 文件内容
xmlString = "<?xml version=\"1.0\" encoding=\"utf-8\" ?>"
+ "<Persons>"
+ "    <Person Name=\"张三\" Sex=\"男\" Age=\"18\" Height =\"180\" ></Person> "
+ "    <Person Name=\"李四\" Sex=\"男\" Age=\"21\" Height =\"170\" ></Person> "
+ "    <Person Name=\"王五\" Sex=\"女\" Age=\"12\" Height =\"120\" ></Person> "
+ "    <Person Name=\"赵六\" Sex=\"男\" Age=\"58\" Height =\"160\" > "
+ "        <Children>"
+ "            <Child Name=\"孩子一\" Sex=\"2\"></Child>"
+ "            <Child Name=\"孩子二\" Sex=\"5\"></Child>"
+ "        </Children>"
+ "    </Person>"
+ "</Persons>";

}

public string XmlDeserialize()
{
if (per != null)
{
StringBuilder sb = new StringBuilder(5000);
XmlSerializer ser = new XmlSerializer(typeof(Persons));
using (TextWriter writer = new StringWriter(sb))
{
ser.Serialize(writer, per);
return writer.ToString();
}
}
else
{
return "实体对象不存在,饭序列化失败";
}
}
public void XmlSerialize()
{
XmlSerializer ser = new XmlSerializer(typeof(Persons));
using (TextReader reader = new StringReader(xmlString))
{
per = (Persons)ser.Deserialize(reader);
}
}
}
}

客户端代码如下：

static void Main(string[] args)
{
MyXmlOptions option = new MyXmlOptions();
option.XmlSerialize();
Console.WriteLine(option.xmlString);
Console.WriteLine(option.XmlDeserialize());

Console.ReadKey();
}

为了使 xml 能够序列化为 实体对象，并且可以反序列化，Poersons 实体 根据xml结构设置如下：

namespace XML序列化
{
[XmlRoot("Persons", IsNullable = false)]
public class Persons
{
[XmlElement("Person")]
public List<Person> Person;
}
public class Person
{
[XmlAttribute("Name")]
public string Name { get; set; }
[XmlAttribute("Sex")]
public string Sex { get; set; }
[XmlAttribute("Age")]
public string Age { get; set; }
[XmlAttribute("Height")]
public string Height { get; set; }
[XmlElement("Children")]
public Children Children;
}
public class Children
{
[XmlElement("Child")]
public List<Child> Child;
}
public class Child
{
[XmlAttribute("Name")]
public string Name { get; set; }
[XmlAttribute("Sex")]
public string Sex { get; set; }
}
}
