Why does WPF support binding to properties of an object, but not fields?（2个答案）

C# WPF，我试图将类'school'（skola）的字段'name'（naziv）绑定到ComboBox，但它从未显示ComboBox中的学校名称...
这是学校班级：

internal class Skola : INotifyPropertyChanged
    {
        public event PropertyChangedEventHandler PropertyChanged;
        private int ID;
        private string naziv;
        private string adresa;
        private string slika;
        private ObservableCollection<Ucenik> ucenici;

        public Skola() { }
        public Skola(int ID, string naziv, string adresa, string slika)
        {
            this.ID = ID;
            this.naziv = naziv;
            this.adresa = adresa;
            this.slika = slika;
            ucenici = new ObservableCollection<Ucenik>();
        }
public string Naziv
        {
            get { return naziv; }
            set
            {
                if (naziv != value)
                {
                    naziv = value;
                    NotifyPropertyChanged("Naziv");
                }
            }
        }

这是主要的：

public partial class MainWindow : Window
    {
        private ObservableCollection<Skola> skole;
        private Skola NEUPISANI = new Skola(0, "", "", "");
        private Skola selected_skolice = new Skola();

        public MainWindow()
        {
            InitializeComponent();
            skole = new ObservableCollection<Skola>();
            Skola s1 = new Skola(1, "Jozef Atila", "Sarplaninska 8", "");
            Skola s2 = new Skola(2, "Bogdana Saputa", "Nardonog fronta 14", "");

            s1.dodajUcenikaTest(new Ucenik("0021233213", "Milan", "Reljin", "Radnicka 12", ""));
            s2.dodajUcenikaTest(new Ucenik("034321233213", "Dragan", "Markovic", "Crnacka 33", ""));

            skole.Add(s1);
            skole.Add(s2);
            skole.Add(NEUPISANI);
            //skolice.DisplayMemberPath = "Naziv";

            DataContext = this;
        }

这是XAML中的ComboBox：

<ComboBox x:Name="skolice" Margin="180 10 180 30" Grid.ColumnSpan="2"
ItemsSource="{Binding Path=skole}" SelectionChanged="skolice_SelectionChanged"></ComboBox>

如果不是所有的东西都是英语的，这太令人困惑了，我会改的！
