How to serialize an array or a list?

I needed to serialize an array few weeks ago and i found one way to perform this serialization.

I performed the serialization for the following objects:

_persons.Add(new Employee { FirstName = "John", LastName = "Smith", Age = 32, EmployeeNumber = 213 });

_persons.Add(new Employee { FirstName = "Mike", LastName = "Stuart", Age = 24, EmployeeNumber = 253 });

_persons.Add(new Employee { FirstName = "John", LastName = "Charles", Age = 53, EmployeeNumber = 214 });

_persons.Add(new Employee { FirstName = "Mary", LastName = "Gomez", Age = 37, EmployeeNumber = 234 });

_persons.Add(new Employee { FirstName = "Javier", LastName = "Matias", Age = 33, EmployeeNumber = 453 });
I used the following code to perform this serialization:
Employee[] allEmployeesArray = allEmployees.ToArray();


String objectSerialized = string.Empty;


XmlSerializer serializer = new XmlSerializer(allEmployeesArray.GetType());


MemoryStream memoryStream = new MemoryStream();

memoryStream.Position = 0;

            

using(XmlTextWriter xmlTextWriter = new XmlTextWriter(memoryStream, Encoding.UTF8))

{

    serializer.Serialize(xmlTextWriter, allEmployeesArray);


     //UTF8 ByteArray To String

     memoryStream = (MemoryStream)xmlTextWriter.BaseStream;

     UTF8Encoding encoding = new UTF8Encoding();


     objectSerialized = encoding.GetString(memoryStream.ToArray());

}


memoryStream.Close();

memoryStream.Dispose();


Console.WriteLine(objectSerialized);
And then i had the following result:
