Sorry I had to haha.

One thing I dont get is when you created the methods. What is {get; set; } all about?

Cheers

Why he did it is called mutator and it is part of encapsulation.  It is one of the concepts of object oriented programming.  You have public and private methods and properties (there are more but I'm simplifying).  Properties have get / set so you can do addtional work when something attempts to fetch or set the value!  This becomes extremely useful in more complex programs.  The get; set; is actually short hand for doing this:

// short hand
public int FirstVar { get; set; }

// long hand
public int SecondVar
{
  get { return _secondVar; }
  set { _secondVar = value; }
}
private int _secondVar;

Note you do not have to do both set and get you can just get the value as you may only want the return value and return means just that return the value i want from the class car to me. So after you get the return value SecondVar you may want to display the result, so in the main class you might have a textbox named mytextbox and you would write , mytextbox.Text = SecondVar and this will display the value in yout textbox.

Moreover, I see that a little bit of an issue or problem for absolute begginners is that this might be a little too assuming/accelerated for absolute begginers... I have purchased a C# book so hopefully if I read that for a couple days and then come back to these lessons they might actually make a bit more sense i total.  I feel that at any part I move on... even when i know how to do sometning, that if I do not understand it it is just going to hurt me in the long run...
