通过XmlSerializer序列化(对象)和反序列化(xml文件)

xml文件

  
    

   
     <?
   
     xml version="1.0"
   
     ?>
   
     

   
     <
   
     User 
   
     xmlns:xsi
   
     ="http://www.w3.org/2001/XMLSchema-instance"
   
      xmlns:xsd
   
     ="http://www.w3.org/2001/XMLSchema"
   
     >
   
     
 
   
     <
   
     Name
   
     >
   
     issac
   
     </
   
     Name
   
     >
   
     
 
   
     <
   
     Age
   
     >
   
     25
   
     </
   
     Age
   
     >
   
     
 
   
     <
   
     Address
   
     >
   
     
 
   
     <
   
     Adrs
   
     >
   
     123
   
     </
   
     Adrs
   
     >
   
     
 
   
     </
   
     Address
   
     >
   
     

   
     </
   
     User
   
     >
  
    

类

[XmlRoot("User")]

    public class User

    {

        [XmlElement("Name")]

        public string Name { get; set; }



        [XmlElement("Age")]

        public int Age { get; set; }



        [XmlElement("Address")]

        public Address Address1 { get; set; }

    }

    public class Address

    {

        [XmlElement("Adrs")]

        public string [] Adrs1 { get; set; }

    }

具体操作

string path = HttpContext.Current.Server.MapPath("~/Config/User.config");

        //反序列化加载xml文件到对象

        protected void Page_Load(object sender, EventArgs e)

        {

            XmlSerializer xs = new XmlSerializer(typeof(User));

            FileStream fs = new FileStream(path, FileMode.Open);

            User user = (User)xs.Deserialize(fs);

            Response.Write(user.Address1.Adrs1[0]);

            fs.Close();

        }

        //序列化对象到xml(修改xml)

        protected void btnUpdata_Click(object sender, EventArgs e)

        {

            User user = new User() { Name = "issac", Age = 25};

            FileStream fs = new FileStream(path, FileMode.Open);

            XmlSerializer xs = new XmlSerializer(typeof(User));

            xs.Serialize(fs, user);

            fs.Close();

        }
