c++ - 如何在 Win8/Metro/WinRT 中获取 DocumentsLibrary 的绝对路径？

Question

我的 manifestappx 文件设置可以访问文档库访问和文件关联，但是当我调用

Windows::Storage::KnownFolders::DocumentsLibrary->Path 

路径返回一个空字符串。如何获得正确返回的路径？

在此先感谢您的帮助

因为 DocumentsLibrary是代表不同位置和文件集合的虚拟位置，它不会有路径:

Libraries, a concept introduced in Windows 7, allow users to view related user content from a single location. Because the library is a virtual location, folders that are added to or removed from a library continue to exist in their original locations as well.

此外，MSDN documentation for StorageFolder.Path状态:

Do not rely on this property to access a folder because some folders may not have file-system paths. For example if the folder is a file group, or is backed by a URI, or was picked using the file picker, the folder is not guaranteed to have a file-system path.
