Windows Phone 8.1应用程序选择器

Question

如何通过代码在WIndows Phone 8.1中显示应用程序选择器？目前我正在使用DisplayApplicationPicker = true，但它无效。任何人都可以给我一个示例代码吗？

Answer 1

你几乎在那里：

// Set the option to show the picker
      var options = new Windows.System.LauncherOptions();
      options.DisplayApplicationPicker = true;

Answer 2

FileOpenPicker filePicker = new FileOpenPicker();
filePicker.SuggestedStartLocation = PickerLocationId.PicturesLibrary;
filePicker.ViewMode = PickerViewMode.Thumbnail;

// Filter to include a sample subset of file types
filePicker.FileTypeFilter.Clear();
filePicker.FileTypeFilter.Add(".bmp");
filePicker.FileTypeFilter.Add(".png");
filePicker.FileTypeFilter.Add(".jpeg");
filePicker.FileTypeFilter.Add(".jpg");

filePicker.PickSingleFileAndContinue();
