C#/ WPF:ViewModel中所有属性的PropertyChanged？

public class PersonViewModel : INotifyPropertyChanged
{
    private Person _person;

    public Person Person
    {
        get => _person;
        set
        {
            _person = value;
            OnPropertyChanged();
        }
    }

    public event PropertyChangedEventHandler PropertyChanged;

    protected virtual void OnPropertyChanged([CallerMemberName] string propertyName = null)
    {
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
    }
}

<TextBox Text="{Binding Person.Name}" />
