WinRT:用于枚举库和已知文件夹之外的文件的应用程序 [英] WinRT: App to enumerate files outside libraries and known folders

问题描述

我正在开发一个 Metro 应用程序，该应用程序在 ListView 控件中显示给定文件夹的内容.MS 决定开发人员不需要 System.IO.Directory 类并将其从框架中完全删除.

I am working on a Metro app that shows the content of a given folder in a ListView control. MS decided that developers don't need the System.IO.Directory class and removed it entirely from the framework.

我正在寻找在 Metro 风格应用程序中枚举 C# 文件的替代方法.我检查了 MS 提供的所有枚举示例，它们似乎都只使用 KnownFolders 类枚举 Windows 库，例如:

I am looking for a replacement to enumerate files in C# in a metro style app. I have checked all the enumeration samples provided by MS and they all seem to only enumerate the Windows Libraries using the KnownFolders class, something like:

StorageFolder picturesFolder = KnownFolders.PicturesLibrary;

并根据您的需要调用 GetFilesAsync() 或 GetFoldersAsync() 方法.如果我只想在图片或音乐库中枚举，这些都是金子.但是，我希望枚举库中未包含的目录中的文件.

and calling the GetFilesAsync() or GetFoldersAsync() methods depending on your needs. These are all gold if I wanted to enumerate only inside the pictures or music library. However I am looking to enumerate files on directories that are not included in a library.

任何人都知道这在 WinRT 中是如何实现的???

Anyone knows how this is possible in WinRT???

推荐答案

根据设计，您在此领域对于 Metro 应用程序的限制非常有限.这个想法是，Metro 应用只能访问它信任访问的内容，因此您可以:

You are, by design, extremely limited in this area for Metro apps. The idea is that a Metro app is only given access to those things that it is trusted to access, so you can either:

1. 访问本地存储，特定于您的应用
2. 访问一些众所周知的存储位置，或
3. 访问特别授予的位置.
