推荐答案

因为

Because DocumentsLibrary is a virtual location representing a collection of different locations and files, it will not have a path:

库是Windows 7中引入的概念，允许用户查看 单个位置的相关用户内容.因为图书馆是一个 虚拟位置，添加到库中或从库中删除的文件夹 仍然存在于其原始位置.

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文档对于StorageFolder.Path 状态:

In addition, the MSDN documentation for StorageFolder.Path states:

请勿依赖此属性访问文件夹，因为某些文件夹 可能没有文件系统路径.例如，如果文件夹是文件 组，或者由URI支持，或者是使用文件选择器选择的 不能保证文件夹具有文件系统路径.

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.
