Does a Form work like a pointer?

Question

Today I tried to create a reusable Framework, and I had no problem to do this... I created a new file "Game.cs" containing the class Game:

class Game
{
    Form Form;

    public Game(Form Form, int Width, int Height)
    {
        //Set Form
        this.Form = Form;
        this.Form.MaximizeBox = false;
        this.Form.FormBorderStyle = FormBorderStyle.Fixed3D;
        this.Form.Size = new Size(Width, Height);
    }
}

Then I add this file into a new Form project, Framework_Demo, using VisualStudio and it contains this:

namespace Framework_Demo
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            //Here I created a new Object game using class Game
            Game game = new Game(this, 600, 600);
        }
    }
}

Maybe this is simple and my question could be obsolete, but why when I debug Framework_Demo appears his Form but also with the properties I set in the costructor of Game class? It's not a problem but I want to know what happens when I set: this.Form = Form. It's really working like a pointer? Can someone explain this behaviour to me? Thank You!

Answer 1

class Game
{
    Form Form;
}

Here the Form field is just a reference to another form, where you get that reference in the constructor of Game class. This is generally done to keep a reference to the owner form inside a child form. When you set Form properties in the constructor, you're actually modifying the owner form.
