[英]WinRT c# load a sqlite database from folder asset
I would like to load a prefab sqlite database from the folder Assets at the launch and copy it in the localstate of the application. 我想在启动时从Assets文件夹加载一个预制sqlite数据库,并将其复制到应用程序的localstate中。
I try a lot of thing and every time I have a "Access denied" or "file not found". 我尝试了很多事情,每次遇到“拒绝访问”或“找不到文件”时。
Have you any idea how to do it ? 你知道怎么做吗?

This is a weird quirk for Win 8 RT. 这是Win 8 RT的怪癖。 I might guess that you have a special extension for your Sqlite db, like ".db" ... a workaround I have used is to use a ".txt" extension for the db in assets.
我可能会猜测您对Sqlite数据库有一个特殊的扩展名,例如“ .db”……我使用的解决方法是对资产中的数据库使用“ .txt”扩展名。
This works on my system without corrupting the file. 这可以在我的系统上运行而不会损坏文件。 I checked the db in Sqlite Database Browser.
我在Sqlite数据库浏览器中检查了数据库。
StorageFile file = await StorageFile.GetFileFromApplicationUriAsync(new Uri("ms-appx:///Assets/db_in_assets.txt"));
await file.CopyAsync(ApplicationData.Current.LocalFolder, "db_in_local.db");
