在Windows应用商店中的列表视图中获取文件的显示名称

Question

I am trying to display the name of the file which is clicked by the user in the listview but the problem is it is displaying the type of item clicked ie Windows.Storage.StorageFile clicked.

Code:

<Page
    x:Class="Notes.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:Notes"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d">

    <GridView Background="White">


        <Button x:Name="Button_Create" Content="Create" Background="Black" Height="104" Width="188" FontSize="32" Click="ButtonCreate_Click"/>
        <ListView IsItemClickEnabled="True" x:Name="filesListView" Foreground="Gray" HorizontalAlignment="Left" SelectionMode="None" ItemClick="filesListView_ItemClick">
            <ListView.ItemTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding DisplayName}" />
                </DataTemplate>
            </ListView.ItemTemplate>
        </ListView>
    </GridView>

</Page>

        private async void ButtonCreate_Click(object sender, RoutedEventArgs e)
        {
            StorageFolder folder = await KnownFolders.MusicLibrary.CreateFolderAsync("Notes", CreationCollisionOption.OpenIfExists);

            //create a file in that folder

            StorageFile file = await folder.CreateFileAsync("MyNotes.txt", CreationCollisionOption.GenerateUniqueName);

            //write to that file

            await Windows.Storage.FileIO.WriteTextAsync(file, "My notes file");

            getFoldersFrommCurrentDirectory();
        }

        private async void getFoldersFrommCurrentDirectory()
        {
            //get folders from current application folder
            StorageFolder folder = await KnownFolders.MusicLibrary.CreateFolderAsync("Notes", CreationCollisionOption.OpenIfExists);
            IReadOnlyList<StorageFile> files = await folder.GetFilesAsync();
            filesListView.ItemsSource = files;
        }




        private async void filesListView_ItemClick(object sender, ItemClickEventArgs e)
        {
            var message = new MessageDialog(e.ClickedItem+ "clicked", "listview item clicked");
            await message.ShowAsync();
        }


        //private async void getFolders()
        //{
        //    //get a folder from known folders
        //    IReadOnlyList<StorageFolder> folders = await KnownFolders.MusicLibrary.GetFoldersAsync();
        //    filesListView.ItemsSource = folders;
        //}


    }


}

Try changing filesListView_ItemClick to

var name = (sender as StorageFile).Name;
var message = new MessageDialog(name + "clicked", "listview item clicked");
await message.ShowAsync();
