如何在 WPF TreeView 中显示类层次结构？

public class MyClass
{
    public string Name { get; set; }
    public List<MyClass> Children { get; set; }

    public MyClass(string name, List<MyClass> children = null)
    {
        Name = name;
        Children = children ?? new List<MyClass>();
    }
}

<TreeView ItemsSource="{Binding ClassHierarchy}">
    <TreeView.ItemTemplate>
        <HierarchicalDataTemplate ItemsSource="{Binding Children}">
            <TextBlock Text="{Binding Name}" />
        </HierarchicalDataTemplate>
    </TreeView.ItemTemplate>
</TreeView>

public class MainViewModel : INotifyPropertyChanged
{
    public event PropertyChangedEventHandler PropertyChanged;

    private List<MyClass> _classHierarchy;
    public List<MyClass> ClassHierarchy
    {
        get => _classHierarchy;
        set
        {
            _classHierarchy = value;
            PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(nameof(ClassHierarchy)));
        }
    }

    public MainViewModel()
    {
        // 创建一个类层次结构的数据源
        ClassHierarchy = new List<MyClass>
        {
            new MyClass("Class A", new List<MyClass>
            {
                new MyClass("Class A1"),
                new MyClass("Class A2")
            }),
            new MyClass("Class B", new List<MyClass>
            {
                new MyClass("Class B1"),
                new MyClass("Class B2")
            })
        };
    }
}

public MainWindow()
{
    InitializeComponent();
    DataContext = new MainViewModel();
}
