Handling XML Files in C # - Library Tips [closed]

I need to manipulate an XML file in C #. This is the first time I'm going to do this, and I wanted some tips. My algorithm is basically this:

Fill an XML from my system data (DB Data)

Ex: I have an entity from which my example data comes Person, that the same by its turn has its attributes.

I need to get this data from Person, and set up an xml.

Read this generated XML file, for execution of an X algorithm, that will perform calculations based on my XML data.

This algorithm will provide me with new data as the results of my study.

I need tips on:

In short, what I want is:

Generate an xml with my entity data,
read this file populating a result entity.
Export my result to xml.

My question is:

1 - What Lib can I use to manipulate these files? That is, there is a library I can use to help me manipulate xml files in C #. What I mean is, so you do not have to do everything in the hand?

2 - Does anyone have an example that you can give me, or any tips on how I can accomplish this task?

3 - Lib to automate this task?

Thank you.

OC # provides some classes ( XmlSerializer, StreamWriter, StreamReader, etc ...) of the namespaces System.Xml and System.IO that you can use to handle files and do XML serialization.

If you can not find a Lib to automate, here's an example:

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

class Program
{
    static void Main(string[] args)
    {
        // Gerar um xml com os dados de minha entidade

        var pessoa = new Pessoa { Id = 1, Nome = "Renan" };

        var xmlSerializer = new XmlSerializer(typeof(Pessoa));
        StreamWriter streamWriter = new StreamWriter("pessoa.xml");

        xmlSerializer.Serialize(streamWriter, pessoa);

        streamWriter.Close();

        // ler esse arquivopopulando uma entidade de resultados.
        // Exportar meu resultado para xml.

        FileStream meuFileStream = new FileStream("pessoa.xml", FileMode.Open);

        Pessoa _pessoa = (Pessoa)xmlSerializer.Deserialize(meuFileStream);

        Console.WriteLine(_pessoa.Nome); // Imprime "Renan"
        Console.ReadLine();
    }
}

public class Pessoa
{
    public int Id { get; set; }

    public string Nome { get; set; }
}

Xml generated and saved in file "... \ bin \ Debug \ person.xml":

<?xml version="1.0" encoding="utf-8"?>
<Pessoa xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <Id>1</Id>
  <Nome>Renan</Nome>
</Pessoa>
