Question

Hello,

I ran into some issues with my code and wanted to ask if anyone can help me fix them. Thank you in advance!

Question:

You and your team of software developers are experiencing problems saving the state of a program between different times that the program is run.

An object oriented program state can be maintained by saving the state of the objects in the program. Also, you can transfer the state of an object between different computer systems by creating the object based on the state once it is saved onto that other computer. In order to provide a way to persist object state, you must serialize objects in C#.

As a team of software developers and using the classes created in the Week Four Learning Team Collaborative Activity, "Learn How to Apply Inheritance Using Class Hierarchies," serialize the objects of the classes from that activity to a file as a Visual Studio^® solution.

Code:

using System;
using System.IO;
using System.Collections;
using System.Runtime.Serialization.Formatters.Binary;
using System.Runtime.Serialization;

namespace Week5_Project
{

public class Animal
{
static void Main()
{
Serialize();
Deserialize();
}

}
{
private int age;
private int weight;
private int height;
}   
// default constructor
public Animal(int age, int weight, int height)
{
this.age = age;
this.weight = weight;
this.height = height;
}
  
public class Cat : Animal
{
public Cat() { }
public Cat(int age, int weight, int height) : base(age, weight, height)
{
}
}
public class Dog : Animal
{
public Dog() { }
public Dog(int age, int weight, int height) : base(age, weight, height)
{
}
}
public class Bird : Animal;
{
public Bird() { }
public Bird(int age, int weight, int height) : base(age, weight, height)
{
}
}
BinaryFormatter formatter = new BinaryFormatter();
try
{
formatter.Serialize(int age, int weight, int height);
}
catch (SerializationException e)
{
Console.WriteLine("Failed to serialize. Reason: " + e.Message);
throw;
}
finally
{
fs.Close();
