问题描述
我对 Windows 应用商店应用程序可用的各种类型的存储有点困惑.
I'm a little bit confused over the various types of storage that is available to Windows Store Apps.
假设我有一个记事本应用程序，用户可以在其中查看、创建和编辑笔记.我将使用什么存储类型来存储笔记?本地存储?将注释写到用户的 Documents 文件夹中的文件中?另外，如果我想通过云同步用户的笔记怎么办?我了解漫游数据的大小限制相当低.
Let's say I had a notepad app, where users can view, create, and edit notes. What storage type would I use for storing the notes? Local storage? Write the notes out to files in the user's Documents folder? Also, what if I wanted to sync a user's notes via the cloud? I understand that Roaming Data has a rather low size limit.
推荐答案
您提到的几乎所有选项都可以用于记事本应用程序.除了漫游数据选项，它只允许您存储 100KB 的数据.
Almost all the options you mention are possible for a notepad application. Except the roaming data option, that only allows you to store 100KB of data.
我将尝试总结您拥有的选项并添加更多选项:
I will try to sum up the options that you have and add a few more:
本地存储您可以轻松地将这些文件添加到 localstorage，您可以将其存储为文件格式或序列化您的对象并存储该对象.很容易实现.缺点是只有您的应用可以访问这些文件.
Localstorage You can easily add these files to localstorage, you can store it in file format or serialize your object and store that one. Very easy to implement. Con is that only your app can access these files.
文档文件夹也是一种选择.通过使用不同的文件选择器变得容易.例如 FileOpenPicker 或FileSavePicker.文件可以以您喜欢的格式存储，并且可以通过其他应用程序或文件资源管理器访问.
Documents folder Also an option. Made easy by use of different filepickers. For example the FileOpenPicker or the FileSavePicker. Files can be stored in the format you like and can be accessed by other apps or through the file explorer.
漫游数据由于空间有限，没有文件选项
Roaming data No option for files due too the limited space
Skydrive API如果您想将文件存储在云端并在任何地方访问它们，您可以考虑 Skydrive api.另请注意，如果您使用文件选择器，您还可以选择将这些文件保存/加载到 skydrive.(尽管在这种情况下，用户选择存储文件的位置.)
Skydrive API If you want to store files in the Cloud and access them anywhere you could consider the skydrive api. Also note that if you use the filepickers you also have the option to save/load these files to skydrive. (Although in that case the user chooses where to store the file.)
Windows Azure 移动服务如果您想将数据存储在云中，则另一种选择.使您能够将数据存储在一个/多个表中.很容易实现.有关移动服务的更多信息，请访问 这里
Windows Azure Mobile Services Another option if you want to store data in the cloud. Gives you the ability to store your data in a table/tables. Very easy to implement. More info about mobile services can be found here
SQL 精简版如果你需要一个本地数据库来存储你的数据，那么 SQLLite 是一个选择.Tim Heuer 写了一篇关于如何在 Windows 8 应用程序中使用 SQLLite 的精彩博文.你可以找到它这里
SQL Lite If you need a local database to store your data than SQLLite can be an option. Tim Heuer has wrote a nice blogpost about how to use SQLLite in your windows 8 app. You can find it here
希望这能稍微澄清一下问题，并让您对如何为您的应用选择什么提供一些想法?
Hopefully this clears up things a bit and gives you some ideas about what to choose for your app?
