c# storing data in xml - how to read and write to it

I am in the process of creating a program for assigning shifts in a rota/schedule and up until now I've been using a hard coded class which contains the records for the people in it.

I'm now looking to store the data properly and was thinking xml could be a good way to do this.

I have a class Person which contains the info for the person and a class MyDataSource which creates 5 instances of the Person class and stores them in a list which I can add or remove to.

I've been looking at using the sterilization to read and write the xml files but am struggling to understand it.

Should I be able to add the code to my existing Person class or do I need to create a separate class to do this?

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Runtime.Serialization;


namespace ShiftSorter
{
    public class Person
    {
        public string name { get; set; }
        public int hours { get; set; }
        public int row { get; set; }
        public string unit { get; set; }

        /// <summary>
        /// Creates a new instance of the object Person.
        /// </summary>
        /// <param name="newName">The name of the person</param>
        public Person(string newName)
        {
            name = newName;
        }
    }
}
