我有一个Employee类,如下所示:

public class Employee : INotifyPropertyChanged
    {
        public Employee()
        {
            _subEmployee = new ObservableCollection<Employee>();
        }

        public string Name { get; set; }

        public ObservableCollection<Employee> SubEmployee
        {
            get { return _subEmployee; }
            set
            {
                _subEmployee = value;
                NotifiyPropertyChanged("SubEmployee");
            }
        }

        ObservableCollection<Employee> _subEmployee;

        public event PropertyChangedEventHandler PropertyChanged;
        void NotifiyPropertyChanged(string property)
        {
            if (PropertyChanged != null)
                PropertyChanged(this, new PropertyChangedEventArgs(property));
        }
    }

我正在Main窗口构造函数中创建一个employee类的集合,并将其添加到一个可观察的员工集合中,如下所示:

public partial class MainWindow : Window
    {
        public ObservableCollection<Employee> Emp { get; private set; }
        public MainWindow()
        {
            InitializeComponent(); …
