是否可以将ObservableCollection绑定到richtextbox

public static class RichTextBoxExtensions
{
    public static readonly DependencyProperty DocumentProperty =
        DependencyProperty.RegisterAttached(
            "Document",
            typeof(FlowDocument),
            typeof(RichTextBoxExtensions),
            new FrameworkPropertyMetadata(
                null,
                FrameworkPropertyMetadataOptions.AffectsRender,
                OnDocumentChanged));

    public static FlowDocument GetDocument(DependencyObject obj)
    {
        return (FlowDocument)obj.GetValue(DocumentProperty);
    }

    public static void SetDocument(DependencyObject obj, FlowDocument value)
    {
        obj.SetValue(DocumentProperty, value);
    }

    private static void OnDocumentChanged(
        DependencyObject obj, DependencyPropertyChangedEventArgs e)
    {
        var richTextBox = (RichTextBox)obj;
        var document = (FlowDocument)e.NewValue;
        richTextBox.Document = document;
    }
}

public class MainViewModel : INotifyPropertyChanged
{
    private ObservableCollection<string> _myCollection;

    public ObservableCollection<string> MyCollection
    {
        get { return _myCollection; }
        set
        {
            _myCollection = value;
            OnPropertyChanged(nameof(MyCollection));
        }
    }

    public MainViewModel()
    {
        MyCollection = new ObservableCollection<string>();
    }

    // 实现INotifyPropertyChanged接口的代码略
}
