How to serialize and deserialize using C# .NET

// Assuming obj is an instance of an object
XmlSerializer x = new XmlSerializer(obj.GetType());
Stream stream = File.Open("data.xml", FileMode.Create);
x.Serialize(stream, persons);
stream.Close();

//Assuming objType is a System.Type set to the type of the object
Stream stream = File.Open("data.xml", FileMode.Open);
XmlSerializer x = new XmlSerializer(objType);
object obj = x.Deserialize(stream);
// Then to cast obj into whatever type it is eg:

objType myObj = obj as objType;

 

实际代码：

Person class:

    public class Person
    {
        public string FirstName;
        public string Lastname;
        public string Class;
    }

系列化：

List<Person> persons = new List<Person>{
            new Person{FirstName ="Jeffrey",Lastname="Yang", Class="5"},
            new Person{FirstName="Zhang",Lastname ="San", Class="5"},
            new Person{FirstName="Li",Lastname ="Si", Class="5"}};

            XmlSerializer x = new XmlSerializer(persons.GetType());
            Stream stream = File.Open("data.xml", FileMode.Create);
            x.Serialize(stream, persons);
            stream.Close();
            Console.WriteLine("Finished");
            Console.ReadLine();

 生成的data.xml:

<?xml version="1.0"?>
<ArrayOfPerson xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <Person>
    <FirstName>Jeffrey</FirstName>
    <Lastname>Yang</Lastname>
    <Class>5</Class>
  </Person>
  <Person>
    <FirstName>Zhang</FirstName>
    <Lastname>San</Lastname>
    <Class>5</Class>
  </Person>
  <Person>
    <FirstName>Li</FirstName>
    <Lastname>Si</Lastname>
    <Class>5</Class>
  </Person>
</ArrayOfPerson>

 

反系列化：

 Stream stream = File.Open("data.xml", FileMode.Open);

            XmlSerializer x = new XmlSerializer(typeof(List<Person>));
            object obj = x.Deserialize(stream);

            List<Person> persons = obj as List<Person>;

            foreach (Person p in persons)
            {
                Console.Write("Name:{0},Class:{1}\r\n", p.FirstName + p.Lastname, p.Class);
            }

            Console.WriteLine();

 运行结果：

Name:JeffreyYang,Class:5
Name:ZhangSan,Class:5
Name:LiSi,Class:5

 

代码排版有点问题，但是在编辑器展不开修改了，郁闷。
