Question

I'm just deploying a winform app that uses SqlCe. I'm using the 'Setup and Deployment\\Setup Project' to customise my deployment. I've created a 'User's Application Data Folder' for all my sdf files to go into (from what I've read this is best practice, correct me if I'm wrong). Now I want to re-map (for lack of a better work) the connection strings from

connectionString="Data Source=|DataDirectory|\My.sdf"

to

connectionString="Data Source=C:\Users\Chris\AppData\Roaming\My Application\My.sdf"

This is where I'm stuck. How do I do this so as it work on multiple users and OS's (I believe putting the sdf files into C:\\Users\\Chris\\AppData\\Roaming\\My Application is best for multi OS's)?

Answer 1

You can retrieve the AppData -folder using the following:

Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData)

Adding your desired path can be done using Path.Combine :

Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData), "Roaming\\My Application");

The result-path is the AppData-folder for the user that runs the code.
