c# – 如何在Windows商店(WinRT)应用程序中启用DocumentsLibrary功能？

我刚刚在Visual Studio中创建了一个新的空白XAML / C# Windows应用商店应用.我尝试使用以下代码在Documents文件夹中创建一个文件：

// DEBUG ONLY:
StorageFile file = await KNownFolders.DocumentsLibrary.CreateFileAsync("hey lol.txt");

但它抛出了这个异常(我预期)：

WinRT information: Access to the specified location (DocumentsLibrary) requires a capability to be declared in the manifest.

哪个好.我期待它.所以我转到Package.appxmanifest并转到Capabilities选项卡,令我惊讶的是,没有列出“DocumentsLibrary”功能.

如果它不存在,我该如何启用它？

解决方法

看起来你的答案是 here.作者在VS2012中显示它,但是从VS2013的列表中删除,引用了MS策略来访问该特定文件夹.

[Although] this capability is gone just from the UI,you still can open appxmanifest source and manually add the capability. The result will probably be the same as before – failure of certification for individual developers,so you better stay away from this trick. Microsoft strongly recommend against using Documents Library capability,suggesting Folder and File Pickers instead.
