Identifying the CPU architecture type using C#

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 from these two? My project targets .NET 2.0!

Solution 1:

You could also try (only works if it's not manipulated):

System.Environment.GetEnvironmentVariable("PROCESSOR_ARCHITECTURE")

Solution 2:

What led me here is checking for a 32 vs 64 bit OS. the highest rated answer is looking at the setting for the Current process. After not finding an answer I found the following setting. Hope this works for you.

bool is64 = System.Environment.Is64BitOperatingSystem
