Windows 8应用商店应用-使用哪种类型的存储? [英] Windows 8 Store Apps — which type of storage to use?
问题描述
对于Windows Store Apps可用的各种存储类型，我有些困惑.
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，创建和编辑记事本.我将使用哪种存储类型来存储笔记?本地存储?将注释写到用户的文档"文件夹中的文件中吗?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对于记事本应用程序都是可能的.除漫游数据选项外，该选项仅允许您存储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.
我将尝试总结您所拥有的选项，并添加更多选项:
I will try to sum up the options that you have and add a few more:
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 也是一个选择.使用不同的文件选择器使操作变得简单.例如， FileOpenPicker 或 FileSavePicker .文件可以以您喜欢的格式存储，并且可以被其他应用程序或通过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，无法选择文件
Roaming data No option for files due too the limited space
Skydrive API 如果要将文件存储在云中并在任何地方访问它们，可以考虑 skydrive api .还要注意，如果使用文件选择器，则还可以选择将这些文件保存/加载到skydrive. (尽管在这种情况下，用户可以选择将文件存储在何处.)
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，则是另一种选择.使您能够将数据存储在一个或多个表中.非常容易实现.有关移动服务的更多信息，请参见这里
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 Lite 如果您需要本地数据库来存储数据，则可以选择使用SQLLite.蒂姆·休尔(Tim Heuer)撰写了一篇不错的博客文章，内容涉及如何在Windows 8应用程序中使用SQLLite.您可以在此处
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
希望这能使您有所了解，并为您提供一些有关为应用程序选择什么的想法?
Hopefully this clears up things a bit and gives you some ideas about what to choose for your app?
