如何仅序列化所选属性

Question

I have one class Person and it has some public properties . Now I want to serialize person class but with some selected properties only . This can be achieve by making that property private but I don't want to change any property as private.

If its not possible using serialisation then, what is another way to create xml doc for object with selected properties only.

Note: All properties must be public.

  class Program
    {
        static void Main(string[] args)
        {
            Person person = new Person();
            using (MemoryStream memoryStream = new MemoryStream())
            {
                XmlSerializer xmlSerializer = new XmlSerializer(person.GetType());
                xmlSerializer.Serialize(memoryStream, person);
                using (FileStream fileStream = File.Create("C://Output.xml"))
                {
                    memoryStream.WriteTo(fileStream);
                    fileStream.Close();
                }
                memoryStream.Close();
            }
        }
    }

    public class Person
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public double Salary { get; set; }

        public Person()
        {
            Id = 1;
            Name = "Sam";
            Salary = 50000.00;
        }
    }

Current Output

  <?xml version="1.0"?>
  <Person xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <Id>1</Id>
    <Name>Sam</Name>
    <Salary>50000</Salary>
  </Person>

Expected Output

  <?xml version="1.0"?>
  <Person xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">   
    <Salary>50000</Salary>
  </Person>

Answer 1

You could use an XmlIgnore attribute..

 public class Person
    {
        [XmlIgnore]
        public int Id { get; set; }
        [XmlIgnore]
        public string Name { get; set; }
        public double Salary { get; set; }

        public Person()
        {
            Id = 1;
            Name = "Sam";
            Salary = 50000.00;
        }
    }

Answer 2

can you give a try to below code and just use XmlIgnore attribute on he properties which you not require :-

    [XmlIgnore]
    public int Id { get; set; }

    [XmlIgnore]
    public string Name { get; set; }

    public double Salary { get; set; }
