c# what is the best way to detect OS ?

[Kate77]

Hello,
Im trying to detect in my application what OS it is running.

I found this code:

// Get the Operating System From Environment Class
OperatingSystem os = Environment.OSVersion;

// Get the version information
Version vs = os.Version;

MessageBox.Show (vs.Major.ToString());
MessageBox.Show (vs.Minor.ToString());
MessageBox.Show (vs.Revision.ToString());
MessageBox.Show (vs.Build.ToString());


2 questions:

is there a better way to detect OS ? maybe WMI ?
how can I know if its XP 32 or XP 64 ?

Thanks

The Environment class works great. As for 64-bit, OSArchitecture in the WMI class gives you "64-bit" (http://msdn2.microsoft.com/En-US/library/aa394239.aspx), but that's probably not what you want to know. More likely you want to know whether you are running in 64-bit or 32-bit mode regardless of the underlying architecture. In this case, just look at IntPtr.Size. If it is 4, then you are running in 32-bit mode. If it is 8, you are running 64-bit. HTH --Sam
