Defining a class of your own

A class is a blueprint for a kind of thing. It bundles the data that describes the thing with the methods that act on it.

A small class

public class Lesson
{
    public string Title;
    public int Minutes;

    public string Summary()
    {
        return Title + " takes about " + Minutes + " minutes";
    }
}

Why this is worth doing

• The names in your code start to match the words in your problem.
• Related values travel together instead of being passed around separately.
• Behaviour that belongs to the data lives next to it.

Next, actually create one and use it in creating objects from your class.
