C#: Is 64bit operating system cross platform (windows, unix, mac) Net 2.0

Question

I want to determine via C#, using NET 2.0 framework, if my operating system is 32 bit or 64 bit.

I can't use Environment.Is64BitOperatingSystem, because is only valid on net4 and above.

Y can't use native dll windows funcions or registry properties, because this is only valid for windows.

Is there any way to check this in unix and mac?

You'll have to decide how to make that check based on the runtime environment. Meaning you'll need all three implementations. — Yuval Itzchakov, Jan 22 '15 at 16:41
Yeah, I've got code for windows, but I can't find anything for MAC OS X and Unix — dhalfageme, Jan 22 '15 at 16:41

Any reason you're stuck on .NET 2.0? Mono has supported .NET 4 for ages. — Jon Skeet, Jan 22 '15 at 16:43
Just how old? .NET 2.0 is really *ancient* - are you willing to support versions of Windows that even Microsoft doesn't support any more? — Jon Skeet, Jan 22 '15 at 17:10

@onu301 The solutions I see there or are Windows specific, either are for NET 4, either say if it's a 64 bit or 32 bit process, but nothing about OS type :( — dhalfageme, Jan 22 '15 at 17:40

Finally, that worked for Linux (Unix and Mac):

    static string GetLinuxArchitectureType()
    {
        Mono.Unix.Native.Utsname result;
        int res = Mono.Unix.Native.Syscall.uname(out result);

        if (res < 0)
            return "N/A";

        return result.machine;
    }

I said I already had this code for windows, it's easy to find. I check first the OS type and use this funcion on unix and mac – dhalfageme Jan 23 '15 at 10:52
To check to OS type you use http://stackoverflow.com/a/9129523/2626313 and in case of `PlatformID.Unix` you branch to this function ? – xmojmr Jan 23 '15 at 11:32

Well, I switch in case > PlatformID.WinCE (Unix, MAC and xBox, the last doesn't make sense for me) – dhalfageme Jan 23 '15 at 12:06
