How to get PEEK/POKE, INP/OUT functionality from C#

[amecklen]

I am developing a board tester, using Measurement Studio, Visual Studio 2010, and C#.net, running on a Windows XP based SBC, embedded system ISA/PCI bus.  I need to be able to read/write byte/word locations in both the CPU’s memory and I/O space.  In the good old days, this was simple to do using, say, the QBasic/VB instructions PEEK, POKE, INP, and OUT.

I’m guessing there must be some way to do this from C# using perhaps the Windows API, Interop, COM objects, and/or a DLL (I’m certainly open to purchasing a third party package if that gets me there quickly).

Any suggestions would be greatly appreciated.

Thanks for the reply, Curt

I see how your suggestion works for implementing a stack, but my requirement is somewhat different.  As an example, here’s the kind of thing I need to do:

write 60h to I/O port 220h    (this selects a bank of memory)

write 0ffh to memory location d8000    (this fills the first byte in the selected memory bank with 1’s)

read memory location d800h    (reads back what was written)

I hope that clarifies things.
