Multithreading implementation -- assign thread to a specific processor?

[Rob R. Ainscough]

Is it possible to assign threads to a specific CPU ID? I'm attempting to
provide performance benefits for 2 and 4 CPU systems and would like to
assign specific threads to a processor, is this possible with .NET? Can't
seem to find anything that would not include such support? API (aka
unmanaged) solution?

Thanks, Rob.

Maybe System.Thread.ProcessorAffinity?

Determining the number of processors:

\\\
Imports System
..
..
..
.... = Environment.GetEnvironmentVariable("NUMBER_OF_PROCESSORS")
///

..NET 2.0: 'Environment.ProcessorCount'.

Thank you, exactly what I needed. .NET 2.0 -- perfect!
