使用XML 序列化和反序列化类对象的方法

.NET  Framework提供了多种序列化对象的方法，二进制，XML,  SOAP，而在系统中应用往往使用对象序列化来暂存或缓存对象状态。

第一步，序列化对象到字串

        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，将字串反序列化为对象

        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是自定义对象,XML 序列化只能序列化public属性，无值的属性不生成XML Tag.

调用示例:

        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
    }

//输出结果

<?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">

  <LastName>Yang</LastName>
