I am trying to create my project to [Serializable] but I dont know if I am doing the right thing.

on all my classes I have added above my class.....  [Serializable]

then in my form I am trying to save it. See code below.

If I choose from my menu Save it jumps to.....saveToolStripMenuItem
here I send  my animalManager object into binaryFileSerialize
but here it throws a catch:

System.Runtime.Serialization.SerializationException was unhandled
  Message="Type 'Animals.AnimalManager' in Assembly 'Animals, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' is not marked as serializable."

Have you tried putting a [Serializable] immediately above line 19?
    public partial class Animal : Form
    {
       [Serializable]
       AnimalManager animalManager = new AnimalManager();

You will need to make the AnimalManager serializable by doing the following:
[Serializable]
public class AnimalManager
{
   public AnimalManager() {}
}

You cannot serialize the inherited class object "Form" you will need to create a serializable class object that does not inherit from Form

I found the error. I had my abstract class as serialzied. That is not allowed. But at least you tried. :-)
