CRC Check

[Dennis]

Does VB.Net have any class that will calculate the CRC of a binary file or
byte array? If not, does anyone have any code that does this. Thanks.

No, but SHA-1 and MD5 are built in.

If not, does anyone have any code that does this. Thanks.

There's some ready-to-use CS code for zip-compatible CRC32 at

Hi,

Sure. But, there are lots of CRCs possible. Do you have a specific one in
mind?

Thanks for link...it works great and just what I needed to calculate the
CRC-32 value.

CRC-32. However, I got the link from David and it works for me. Thanks for
answering my post.
