What would a 32-bit application running on Windows 7 return for the below?
Environment.GetFolderPath(Environment.SpecialFolder.ProgramFiles)
C:\Program Files (x86) or C:\Program Files?
回答1:
On 32 bit Windows 7 you should get "C:\Program Files", on 64 bit "C:\Program Files (x86)".
回答2:
It doesn't matter what it returns. Either value will map to the same folder, file system virtualization will always map it to (x86) for a 32-bit app.

Well I'm running Windows 7 Ultimate 32 bit so I wanted to know for sure what was returned, so I put this into a console application to see what was returned
Console.WriteLine(Environment.GetFolderPath(Environment.SpecialFolder.ProgramFiles));
And it returned C:\Program Files

C:\Program Files (x86)
