It's processor Affinity, not Infinity.

It's handled via the Windows API calls for SetThreadAffinityMask and
SetProcessAffinityMask. You probably won't be able to easily do it at the
thread level, as matching a managed thread to a thread handle is pretty
tough. Setting it for the entire process is pretty easy as the process
handle is easily obtained.

Do you mind if I ask why you want to do this?

Both the Process affinity and the Thread affinity can be set using the
System.Diagnostics namespace.
The *process* affinity can be set using ProcessorAffinity property of the
Process class, while the thread affinity can be set using the
ProcessorAffinity property of the ProcessThread class.
Question is - why do you think you need this?

Doh... I didn't even think to check to see if there were managed
equivalents. I just assumed there weren't because, well, hell, how often
does anyone every need to use it. I too am quite curious as to why the
poster wants to use it.

Well, IMO, these managed equivalents, shouldn't have been in the Framework
to begin with, user class applications never need these, and if you think
you need them, you are probably doing something wrong.
