Xceed.Compression.Formats Assembly > Xceed.Compression.Formats Namespace > ChecksumStream Class > CalculateCrc32 Method : CalculateCrc32(Byte[],Int32,Int32,Int32) Method
The byte array whose checksum will be calculated.
The zero-based byte offset in buffer at which to begin reading bytes.
The number of bytes to read from buffer.
The CRC32 checksum from a previous call to CalculateCrc32 or 0 if a new CRC should be calculated.
Calculates a CRC32 checksum for the specified byte array.
