在地铁，什么是FolderInformation和StorageFolder之间的区别 [英] In metro, what's the difference between FolderInformation and StorageFolder

问题描述

FolderInformation 的方法/属性几乎相同与 StorageFolder 的。  我想不通为什么的WinRT API提供了 FolderInformation 和 StorageFolder 为好。如果我给你从创建的列表FileInformationFactory.GetFoldersAsync（）到的ItemsControl ，它从上市创造不同 StorageFolder.CreateFolderAsync（）？ 该文件说， FolderInformation 提供同步访问，但我不知道什么时候这个问题会发生。

FolderInformation's methods/properties are nearly the same with StorageFolder's. I can't figure out why WinRT api provides FolderInformation and StorageFolder as well. If I assign the list created from FileInformationFactory.GetFoldersAsync() to an ItemsControl, does it differ from the listed created from StorageFolder.CreateFolderAsync() ? The document says the FolderInformation provides synchronous access, but I don't know when the issue would happen.

有一个缺点我在 FolderInformation 发现的是它只能从 FileInformationFactory 创建。所以，我认为这是不可能创建一个 FolderInformation 为 KnownFolders.PicturesLibrary 。

The one drawback I found in FolderInformation is it could only be created from FileInformationFactory. So I think it's impossible to create a FolderInformation for the KnownFolders.PicturesLibrary.

推荐答案

FolderInformation，您可以作用于文件夹本身（如移动，删除，重命名它等） <一href="http://msdn.microsoft.com/en-us/library/windows/apps/windows.storage.bulkaccess.folderinformation.aspx" rel="nofollow">http://msdn.microsoft.com/en-us/library/windows/apps/windows.storage.bulkaccess.folderinformation.aspx

FolderInformation lets you act on the Folder itself (as in move it, delete it, rename it etc.) http://msdn.microsoft.com/en-us/library/windows/apps/windows.storage.bulkaccess.folderinformation.aspx

而StorageFolder，您可以作用于文件夹的内容（如在文件夹中创建一个新的文件，创建一个新的子文件夹中的文件夹中，您可以通过文件夹等所有文件） 的http://msdn.microsoft.com/en-us/library/windows/apps/windows.storage.storagefolder.aspx

Whereas StorageFolder lets you act on the contents of the folder (as in create a new file in the folder, create a new sub-folder in the folder, get all the files from the folder etc.) http://msdn.microsoft.com/en-us/library/windows/apps/windows.storage.storagefolder.aspx
