BinaryFormatter: Binary serialization

Create a C# program to serialize and deserialize objects in binary format. To do this you can use the BinaryFormatter class included in the System.Runtime.Serialization namespace.

First implement a Person class with three properties (Name, Age and City). The City class will have two properties (Name and Population). Then create a person object and use the BinaryFormatter object's serializer to save the data in a binary file, later deserialize the file and print it on screen. Remember to prepare a ToString () method to print the Persona class.

        Person person = new Person(){ Name = "Nauj", Age = 26, City = new City(){ Name = "Spain", Population = 13456766 } };

        Serialize(person);
        person = Deserialize();

        Console.WriteLine(person.ToString());
    }

    public static void Serialize(Person p)
    {
        IFormatter formatter = new BinaryFormatter();
        using (Stream stream = new FileStream(nameFile, 
            FileMode.Create, FileAccess.Write, FileShare.None))
        {
            formatter.Serialize(stream, p);
        }
    }

    public static Person Deserialize()
    {
        Person p;
        IFormatter formatter = new BinaryFormatter();

        using (Stream stream = new FileStream(nameFile,
           FileMode.Open, FileAccess.Read, FileShare.Read))

            return str.ToString();
