How can i get the path of the current user's "Application Data" folder?

1)how can i find out the Windows Installation drive in which the user is working.? I need this to navigate to the ApplicationData in DocumentsandSettings.

2)Also how can i get the user name too so that i can goto ApplicaitionData.? Eg: "D:\Documents and Settings\user\Application Data".

Solution 1:

Look at combining Environment.GetFolderPath and Environment.SpecialFolder to do this.

Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData)

Solution 2:

Depending on what you are doing you might also want to look at

Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData)

If the user is on a domain it will only be stored in their local AppData folder and not synced with their roaming profile.
