  尝试，

  var folder = await Windows.ApplicationModel.Package.Current.InstalledLocation.GetFolderAsync("Assets");
  var files = await folder.GetFilesAsync();
  

  并将文件计为

  var filesCount = files.Count;
  

  并且您可以获取特定扩展名的文件数

  var pngFileCount = files.Where(file => file.FileType == ".png").Select(f => f).ToList().Count;
  

  希望这会对你有所帮助:)

  干得好 .

  var folder = await Package.Current.InstalledLocation.GetFolderAsync("Assets");
  var options = new QueryOptions { FileTypeFilter = { ".png", ".jpg" } };
  var query = folder.CreateFileQueryWithOptions(options);
  var files = await query.GetFilesAsync();
  foreach (var file in files)
  {
      // TODO
  }
  

  我想指出这适用于Windows但不适用于Windows Phone . 还没 .

  最好的是运气 .
