How can I serialize an object to XML in C#?

How can I serialize an object to XML in C#?

You can use the XmlSerializer class in C#. First, create an instance of XmlSerializer with the type of the object you want to serialize.

Can you show me a code example?

Sure! Here's a simple example:

using System;
using System.IO;
using System.Xml.Serialization;

[XmlRoot("Person")]
public class Person {
    public string Name { get; set; }
    public int Age { get; set; }
}

class Program {
    static void Main() {
        Person person = new Person { Name = "John", Age = 30 };
        XmlSerializer serializer = new XmlSerializer(typeof(Person));
        using (TextWriter writer = new StreamWriter("person.xml")) {
            serializer.Serialize(writer, person);
        }
    }
}

This code serializes a Person object to an XML file.

What if I want to deserialize the XML back to an object?

You can use the same XmlSerializer class for deserialization. Here's how:

using (TextReader reader = new StreamReader("person.xml")) {
    Person deserializedPerson = (Person)serializer.Deserialize(reader);
}

Are there any attributes I can use to customize the serialization?

Yes, you can use attributes like [XmlElement], [XmlAttribute], and [XmlIgnore] to control how properties are serialized.
