InsertOnSubmit 给出了这个错误。我该如何解决？

Question

InsertOnSubmit 给出错误 "there is no argument given that corresponds to the required formal parameter 'entity' of table.InsertOnSubmit(chalet)"。我该如何解决这个问题？

这是我的代码。

public partial class MainWindow : Window
{
    DataClasses1DataContext db = new DataClasses1DataContext();
    public MainWindow()
    {
        InitializeComponent();
    }

    private void Button_Click(object sender, RoutedEventArgs e)
    {
        chalet hetHuis = new chalet();

        hetHuis.Naamcode = naamcode.Text;
        hetHuis.Persoonaantal = Convert.ToInt32(personenaantal.Text);
        hetHuis.Klasse = Convert.ToString(klasse.SelectedItem);

        db.chalets.InsertOnSubmit();
        db.SubmitChanges();
    }
}

它在 db.chalets.InsertOnSubmit();

处给出了错误

像db.chalets.InsertOnSubmit(hetHuis);

一样传递db.chalets.InsertOnSubmit();中的实体
