CRC32VFP is a proposed name of a class I would have to use to obtain the equivalent of what VFP does. After more research, it turns out that the way they do it is like this:

lcCRC32 = SYS(2007, lcFileData, 0, 1)

So, I am not sure I can get an equivalent of that in .NET.

Is that Polynomal PKZip CRC complaint BTW? If yes, with that, they never get negative values.
