C# operating system installed directory

Question

How do I find the drive, using C#, in which I installed the operating system (say, Windows 7)? Then I have to get the Program Files directory.

see http://stackoverflow.com/questions/194157/c-how-to-get-program-files-x86-on-vista-x64 for an example on Vista — Marijn, May 26 '11 at 10:02

Use Environment.GetFolderPath(Environment.SpecialFolder.System);, and for the program files folder use Environment.GetFolderPath(Environment.SpecialFolder.ProgramFiles);.

Have a look at this link. Environment.GetEnvironmentVariable hopefully, would do the job for you.

string systemDrive = Path.GetRoot(Environment.GetFolderPath(Environment.SpecialFolder.System));
string progamFilesPath = Environment.GetFolderPath(Environment.SpecialFolder.ProgramFiles);
