Windows Phone 8.1應用程序選擇器

Question

如何通過代碼在WIndows Phone 8.1中顯示文件的應用程序選擇器？ 目前，我正在使用DisplayApplicationPicker = true但無法正常工作。 有人可以給我示例代碼嗎？

Answer 1

您幾乎在哪里：

// 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();
