列表视图中的文本块不显示绑定数据 - WPF XAML

Question

我正在尝试将数据与listview中的文本块绑定，但它不显示数据。但是，当我运行应用程序时，我可以看到列表已创建，但它显示空数据。请参阅下图中的空白数据列表：

这是我的XAML代码：

<ListView Margin="20,0,0,20" x:Name="listView_attachedFiles">
    <ListView.ItemTemplate>
        <DataTemplate>
            <TextBlock Width="100" Text="{Binding AttachedFiles, Mode=TwoWay, NotifyOnTargetUpdated=True}">
                <Hyperlink>
                </Hyperlink>
            </TextBlock>
        </DataTemplate>
    </ListView.ItemTemplate>
</ListView>

这是C＃代码

public class ListviewModel : INotifyPropertyChanged
{
    private ObservableCollection<string> _attachedfiles;
    public ObservableCollection<string> AttachedFiles
    {
        get { return _attachedfiles; }
        set
        {

            _attachedfiles = value;
            OnPropertyChanged("AttachedFiles");

        }
    }

    public ListviewModel()
    {
        AttachedFiles = new ObservableCollection<string>();
    }

    public event PropertyChangedEventHandler PropertyChanged;

    /// <summary>
    /// Raises this object's PropertyChanged event.
    /// </summary>
    /// <param name="propertyName">The property that has a new value.</param>
    protected void OnPropertyChanged(string propertyName)
    {
        PropertyChangedEventHandler handler = PropertyChanged;
        if (handler != null)
        {
            handler(this, new PropertyChangedEventArgs(propertyName));
        }
    }
}

这是我填充数据的方式：

// I'm calling this method to attach the list of filenames       
    private void ExecuteMethod_AttachFile(object Parameter)
    {

        OpenFileDialog ofd = new OpenFileDialog();
        ofd.Multiselect = true;
        if (ofd.ShowDialog() == true)
        {
            AttachedFileLocation = ofd.FileNames.ToList();

            // adding bind data to the list of viewmodel: adding attachefile names
            foreach (var file in AttachedFileLocation)
            {
                FileInfo info = new FileInfo(file);
                DMS_Form.Instance.ListofViewModel.AttachedFiles.Add(info.Name + "  X");
            }

        }
    }

这是我如何在WPF表单的构造函数中附加itemssource引用。

//Binding the list of attached files with the listview
listView_attachedFiles.ItemsSource = ListofViewModel.AttachedFiles;

请帮我弄明白我在哪里弄错了。任何帮助将受到高度赞赏。谢谢
