I have not found any good method to get the OS architecture on Google. What I found was how to tell whether the process is 32-bit or 64-bit.
我还没有找到任何在 Google 上获取操作系统架构的好方法。我发现的是如何判断进程是 32 位还是 64 位。
If there isn't anyway to find out in .NET 2.0 please tell me. :)
如果无论如何都无法在 .NET 2.0 中找到，请告诉我。:)

Not the accepted answer in the duplicate question, but this is how I'd do it:
不是重复问题中接受的答案，但这就是我的做法：
Use GetEnvironmentVariableto look for the PROCESSOR_ARCHITEW6432 variable. If it doesn't exist, you must be running 32bit:
使用GetEnvironmentVariable去寻找PROCESSOR_ARCHITEW6432变量。如果它不存在，则您必须运行 32 位：
bool is64bit = !string.IsNullOrEmpty(
Environment.GetEnvironmentVariable("PROCESSOR_ARCHITEW6432"));
