1.xml 集合序列化和发序列化  
1.1 对象结构  
public class People  
\{  
\[XmlAttribute("NAME")\]  
public string Name  
\{ set; get; \}  
\[XmlAttribute("AGE")\]  
public int Age  
\{ set; get; \}  
\}  
\[XmlRoot("Root")\]  
public class Student : People  
\{  
\[XmlElement("CLASS")\]  
public string Class  
\{ set; get; \}  
\[XmlElement("NUMBER")\]  
public int Number  
\{ set; get; \}  
\}

2.对象序列化为 xml 文件  
public void ToXML()  
\{

List<Student> stuList = new List<Student>();  
stuList.Add(new Student() \{ Age = 10, Number = 1, Name = "Tom", Class = "Class One" \});  
stuList.Add(new Student() \{ Age = 11, Number = 2, Name = "Jay", Class = "Class Two" \});  
stuList.Add(new Student() \{ Age = 12, Number = 3, Name = "Pet", Class = "Class One" \});  
stuList.Add(new Student() \{ Age = 13, Number = 4, Name = "May", Class = "Class Three" \});  
stuList.Add(new Student() \{ Age = 14, Number = 5, Name = "Soy", Class = "Class Two" \});  
XmlSerializer ser = new XmlSerializer(typeof(List<Student>));  
ser.Serialize(File.Create("C:\\\\x.xml"), stuList);

3.序列化后 xml 内容  
<?xml version="1.0"?>  
<ArrayOfStudent xmlns:xsi="[http://www.w3.org/2001/XMLSchema-instance][http_www.w3.org_2001_XMLSchema-instance]" xmlns:xsd="[http://www.w3.org/2001/XMLSchema][http_www.w3.org_2001_XMLSchema]">  
<Student NAME="Tom" AGE="10">  
<CLASS>Class One</CLASS>  
<NUMBER>1</NUMBER>  
</Student>  
<Student NAME="Jay" AGE="11">  
<CLASS>Class Two</CLASS>  
<NUMBER>2</NUMBER>  
</Student>  
<Student NAME="Pet" AGE="12">  
<CLASS>Class One</CLASS>  
<NUMBER>3</NUMBER>  
</Student>  
<Student NAME="May" AGE="13">  
<CLASS>Class Three</CLASS>  
<NUMBER>4</NUMBER>  
</Student>  
<Student NAME="Soy" AGE="14">  
<CLASS>Class Two</CLASS>  
<NUMBER>5</NUMBER>  
</Student>  
</ArrayOfStudent>

4.将 xml 反序列化为对象  
public List<Student> ToStudent()  
\{  
XmlSerializer ser = new XmlSerializer(typeof(List<Student>));  
List<Student> stuList = ser.Deserialize(File.OpenRead("C:\\\\x.xml")) as List<Student>;

return stuList;  
\}

5.测试脚本  
5.1测试类  
public class Test  
\{  
public class People  
\{  
\[XmlAttribute("NAME")\]  
public string Name  
\{ set; get; \}  
\[XmlAttribute("AGE")\]  
public int Age  
\{ set; get; \}  
\}  
\[XmlRoot("Root")\]  
public class Student : People  
\{  
\[XmlElement("CLASS")\]  
public string Class  
\{ set; get; \}  
\[XmlElement("NUMBER")\]  
public int Number  
\{ set; get; \}  
\}

public void ToXML()  
\{

public List<Student> ToStudent()  
\{  
XmlSerializer ser = new XmlSerializer(typeof(List<Student>));  
List<Student> stuList = ser.Deserialize(File.OpenRead("C:\\\\x.xml")) as List<Student>;

return stuList;  
\}

5.2测试脚本  
private void btnOk\_Click(object sender, EventArgs e)  
\{  
Test t = new Test();  
t.ToXML();  
t.ToStudent();  
\}

注意：xml 的存储结构类似 C\# 中的继承，所以如果节点有嵌套，需要考虑是否需要用到类继承的数据结构。
