Identifying the CPU architecture type using C#

Question

I want to check which CPU architecture is the user running, is it i386 or X64 or AMD64. I want to do it in C#. I know i can try WMI or Registry. Is there any other way apart

Answer 1

Here's what I did:

public static bool Isx86()
{
    return (Environment.ExpandEnvironmentVariables("%ProgramFiles(x86)%").Length == 0);
}

If you're on 64 bit architecture you'll have two program file env variables. If you're on x86, you'll only have the one.
