Question

I’m trying to find a file inside the system directory.
The problem is that when using

Environment.SystemDirectory

On a x64 machine, i’m still getting the System32 directory, instead of the Systemwow64 directory.

I need to get the “System32” directory on x86 machines, and “SystemWow64” directory on x64

Any ideas?

EDIT:
To find the SysWow64 i’m using the “GetSystemWow64Directory”. (more information here: pinvoke
Notice that on non-x64 machines – result is ‘0’.
Hope this helps someone

Answer 1

Using the SHGetSpecialFolderPath function:

[DllImport("shell32.dll")]
public static extern bool SHGetSpecialFolderPath(IntPtr hwndOwner, [Out]StringBuilder lpszPath, int nFolder, bool fCreate);

string GetSystemDirectory()
{
    StringBuilder path = new StringBuilder(260);
    SHGetSpecialFolderPath(IntPtr.Zero,path,0x0029,false);
    return path.ToString()
}

Will return System32 on x86, and SysWow64 on x64
