CRC Class

Hi!

I've got a problem... I am working on a protocoll to affect a modeltrain.

But for the Protocoll I need CRC 8 oder CRC 16 Checksum...

So my question is:

Does anybody has or knows where to get a .NET Class which can calculate CRC 8 oder CRC 16 Checksumms

greetings

Here is a little list:

A little example if you want to write you own method, here is a page about the CRC:

static long ComputeCRC(byte[] val)
{
long crc;
long q;
byte c;
crc = 0;
for (int i=0; i< val.Length; i++)
{
c = val Idea

;
q = (crc ^ c) & 0x0f;
crc = (crc >> 4) ^ (q * 0x1081);
q = (crc ^ (c >> 4)) & 0xf;
crc = (crc >> 4) ^ (q * 0x1081);
}
return crc;
}
