推荐答案

Windows Phone 8 不允许免费直接访问用户的硬盘来读取或写入文件.您必须使用特定于用例的 API，具体取决于您尝试存储的媒体类型.我过去回答过一个类似的问题，关于 WP8 对已知文件类型的读写访问@ Windows Phone 8:媒体文件访问

Windows Phone 8 doesn't allow for free-for-all direct access to the user's hard-drive to read or write files. You'll have to use usecase specific APIs depending on the type of media you're trying to store. I've answered a similar question in the past regarding WP8's read-write access for known file types @ Windows Phone 8: Media file access

一些亮点:

1. 您的应用程序可以使用 IsoStore 来读取 &写入只能由您的应用程序访问的文件.请参阅 IsolatedStorageFile API 或 ApplicationData.当前.LocalFolder API.

1. Your app can use IsoStore to read & write files only accessable to your app. See IsolatedStorageFile API or ApplicationData.Current.LocalFolder API for that.

您可以使用 MediaLibrary.SavePicture 或 MediaLibrary.SavePictureToCameraRoll 方法.

You can store pictures using MediaLibrary.SavePicture or MediaLibrary.SavePictureToCameraRoll methods.

您可以使用 MediaLibraty.SaveSong 方法存储歌曲.

You can store songs using MediaLibraty.SaveSong method.

除此之外，我从头顶上对操作系统的任何其他文件写入 API 都不熟悉.您可能可以使用远程服务器，但仅此而已.

Other then those APIs I'm not familiar with any other file write APIs to the OS from the top of my head. You can probably use a remote server, but that's pretty much it.
