I'm trying to learn List<> in C#. I made a test program that takes the result of three textboxes and inputs it in a multiline textbox, after I put them in a list (to later save the list to file).

Here is my class declaration:

```
public class Film
    {
        public Film (string Num, string Title, string Categ)
        {
            this.Numero = Num;
            this.Titre = Title;
            this.Categorie = Categ;
        }

        public string Numero;
        public string Titre;
        public string Categorie;

    }

```

Now I instantiate the list:

```
List<Film> ListeFilms = new List<Film>();

```

And here is my event:

```
private void btSaveMovie_Click(object sender, EventArgs e)
    {
        var MyMovie = new Film(txtNum.Text, txtTitre.Text, cbCateg.Text);

        ListeFilms.Add(MyMovie);
        foreach (Film x in ListeFilms)
        {
            txtAffichage.AppendText(x.ToString());
        }
    }

```

Now when I run, all that is written in the text box is:

```
test_1.Form1+Film

```

What did I do wrong?
