CRC Check

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.

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?
