C#: How to tell architecture of machine

How to detect Windows 64 bit platform with .net?

At a low level, how can I tell if a particular machine is 64-bit or 32-bit? I have a Firebird d/b that appears to be sensitive to the 64-bit architecture, and I want to verify that.

It sounds like the Environment.Is64BitOperatingSystem property is exactly what you need.

You can tell if you are running under a 64 bit OS with the Environment.Is64BitOperatingSystem property. If you have a 64bit machine but with a 32 bit OS installed then everything will be running as 32 bit.
