c#序列化 xml
要序列化的对象的类：
[Serializable]
public class Person
{
private string name;
public string Name
{
get
{
return name;
}
set
{
name=value;
}
}
public string Sex;
public int Age=31;
public Course[] Courses;
public Person()
{
}
public Person(string Name)
{
name=Name;
Sex="男";
}
}
[Serializable]
public class Course
{
public string Name;
[XmlIgnore]public string Description;
public Course()
{
}
public Course(string name,string description)
{
Name=name;
Description=description;
}
}
进行序列化及反序列化的测试类：
class Test
{
//序列化
public void Serialiaze()
{
Person c=new Person("cyj")
c.Courses=new Course[2];
c.Courses[0]=new Course("英语","交流工具")
c.Courses[1]=new Course("数学","自然科学")
XmlSerializer xs=new XmlSerializer(typeof(Person));
Stream stream = new FileStream("c:\\cyj.xml", FileMode.Create, FileAccess.Write, FileShare.ReadWrite);
xs.Serialize(stream, c);
stream.Close();
}
//反序列化
public void Deserialize()
{
XmlSerializer xs=new XmlSerializer(typeof(Person));
Stream stream = new FileStream("c:\\cyj.xml", FileMode.Open, FileAccess.Read, FileShare.ReadWrite);
Person p=(Person)xs.Deserialize(stream);
Console.WriteLine(p.Name);
Console.WriteLine(p.Age.ToString());
Console.WriteLine(p.Courses.Length.ToString());
Console.Read();
}
}
格式化后Xml的文档内容为：
<?xml version="1.0"?>
<Person xmlns:xsd=http://www.w3.org/2001/XMLSchema xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<Sex>男</Sex>
<Age>31</Age>
<Courses>
<Course>
<Name>英语</Name>
</Course>
<Course>
<Name>数学</Name>
</Course>
</Courses>
<Name>cyj</Name>
</Person>

这里是一个Demo，简单实现了C#中对象的XML序列化技术。 首先，我们定义一个需要序列化的对象： using System; namespace XMLSerializer { /// <summary> /// 测试类 /// </summary> public class TestXML { public string name; public string sex; public string age; } } 然后我们就可以在程序中使用这个类构造对象，对其序列化到XML文档。  private void button1_Click(object sender, System.EventArgs e) { TestXML a = new TestXML(); a.name = tbName.Text; a.sex = tbSex.Text; a.age = tbAge.Text;
SaveFileDialog of = new SaveFileDialog(); of.Filter = " XML文档|*.XML"; if( of.ShowDialog() == DialogResult.OK ) { try { Stream s = of.OpenFile();
new XmlSerializer( a.GetType() ).Serialize( s, a ); s.Close(); } catch( Exception ex ) { MessageBox.Show( ex.Message ); } } }
最后，从XML文档中反序列化出对象 private void button2_Click(object sender, System.EventArgs e) { OpenFileDialog o = new OpenFileDialog(); o.Filter = " XML文档|*.XML|所有文件|*.*"; if( o.ShowDialog() == DialogResult.OK ) { try { XmlSerializer xs = new XmlSerializer( typeof( TestXML ) ); Stream s = o.OpenFile(); TestXML a = xs.Deserialize( s ) as TestXML;
tbName.Text = a.name; tbSex.Text = a.sex; tbAge.Text = a.age; s.Close(); } catch( Exception ex ) { MessageBox.Show( ex.Message ); } } } |
