XML序列化對象

NET Framework提供了多種序列化對象的方法，二進制，XML, SOAP，而在系統中應用往往使用對象序列化來暫存或緩存對象狀態。

NET Framework提供了多種序列化對象的方法，二進制，XML, SOAP，而在系統中應用往往使用對象序列化來暫存或緩存對象狀態。

第一步，序列化對象到字串

public static string GetObjectXML(object e)
        {
            XmlSerializer serilizer = new XmlSerializer(typeof(Employee));

            System.Text.StringBuilder sbXML = new StringBuilder();

            System.IO.StringWriter writer = new System.IO.StringWriter(sbXML);

            serilizer.Serialize(writer, e);

            writer.Close();

            return sbXML.ToString();
        }

第二步，將字串反序列化為對象

        public static Employee GetObjectFromXML(string xml)
        {
            XmlSerializer serializer = new XmlSerializer(typeof(Employee));

            System.IO.StringReader reader = new System.IO.StringReader(xml);

            Employee emp = (Employee)serializer.Deserialize(reader);

            return emp;
        }

Employee是自定義對象,XML 序列化只能序列化public屬性，無值的屬性不生成XML Tag.

調用示例:

        static void Main(string[] args)
        {
            Employee emp = new Employee();
            emp.FirstName = "Johnson";
            emp.LastName = "Yang";
            emp.Id = 1;

            Console.WriteLine("{0}", GetObjectXML(emp));

            Console.WriteLine("First Name = {0}", GetObjectFromXML(GetObjectXML(emp)).FirstName);
        }

//Employee

    public class Employee
    {
        member variables#region member variables
        private int _id;
        private string _firstName;
        private string _lastName;
        private string _sex;
        private DateTime _birthday = DateTime.Now;
        #endregion

        public properties#region public properties
        public int Id
        {
            get { return _id; }
            set { _id = value; }
        }
        public string FirstName
        {
            get { return _firstName; }
            set { _firstName = value; }
        }
        public string LastName
        {
            get { return _lastName; }
            set { _lastName = value; }
        }
        public string Sex
        {
            get { return _sex; }
            set { _sex = value; }
        }
        public DateTime BirthDay
        {
            get { return _birthday; }
            set { _birthday = value; }
        }
        #endregion
    }

//輸出結果

<?xml version="1.0" encoding="utf-16"?>
<Employee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http:
//www.w3.org/2001/XMLSchema">
<Id>1</Id>
<FirstName>Johnson</FirstName>
<LastName>Yang</LastName>
<BirthDay>2007-03-13T21:51:33.078125+08:00</BirthDay>
</Employee>
First Name = Johnson
