任何用户/管理员都可以具有读/写访问权限的系统位置

Question

I have a wpf application. It uses SQL CE database.

I am creating sdf file in user specific AppData folder. But for individual application this will create individual sdf file's.

I don't want this thing. I just want a common database location in which any user/administrator can have read/write access permission.

Which location is preferred for such scenario?

Answer 1

Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData)

This gives you the root folder where all app data is shared. Create a subfolder here for your app and store the file there.

Answer 2

Unfortunately the common place only available and everyone will suggest is systems ProgramData directory. which is normally located under "C:\\ProgramData" on vista and seven .

and for XP it is "C:\\Documents and Settings\\All Users\\Application Data"

If your application runs under administrative mode then there is no need of read/write access permission.

But if you have planned to run the application under Standard account then you may need write permission. but it depends on System UAC.

So it is suggested to create a folder for your db under ProgramData, put your db there which suppose to use by all other app from different user and grant write/modify access permission to this folder for all users.
