(About the author)
 
     The attached class contains a lot of bit manipulation routines. Here are some of them 1) Right/Left shifting, both logical & arithmetic logic, both truncation & wrapping, 2) Get/Set any bits or a range of bits, 3) Convert data types and byte arrays to a string of bits, 4) Convert a string of bits to byte,int,long 5) CRC32 calcs on arrays and strings, 6) and many more. Let me know if you see any errors or potential improvements.

Note: Due to the size or complexity of this submission, the author has submitted it as a .zip file to shorten your download time. Afterdownloading it, you will need a program like Winzip to decompress it.Virus note:All files are scanned once-a-day by Planet Source Code for viruses, but new viruses come out every day, so no prevention program can catch 100% of them. For your own safety, please:
  1. Re-scan downloaded files using your personal virus checker before using it.
  2. NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.
  3. Scan the source code with Minnow's Project Scanner

If you don't have a virus scanner, you can get one at many places on the net including:McAfee.com

Hi Keith, you think implement the CRC32 for files?

@Heriberto, it can be done easily with the existing code:
1. Open file as binary, load entire file or chunks of the file into byte array
2. Send complete or partial array to the CRC32_ByteArray
