Метод	Описание
CRC32Calculator ( ) : System
CalculateCrc32 ( byte buffer ) : int
CalculateCrc32 ( string inputData ) : int
Combine ( int crc, int length ) : void	Combines the given CRC32 value with the current running total. This is useful when using a divide-and-conquer approach to calculating a CRC. Multiple threads can each calculate a CRC32 on a segment of the data, and then combine the individual CRC32 values at the end.
Reset ( ) : void	reset before reuse
SlurpBlock ( byte block ) : void
SlurpBlock ( byte block, int offset, int count ) : void	Update the value for the running CRC32 using the given block of bytes. This is useful when using the CRC32() class in a Stream.

Приватные методы

Метод	Описание
ComputeCrc32 ( Int32 W, byte B ) : Int32	Get the CRC32 for the given (word,byte) combo. This is a computation defined by PKzip.
_InternalComputeCrc32 ( UInt32 W, byte B ) : Int32
gf2_matrix_square ( uint square, uint mat ) : void
gf2_matrix_times ( uint matrix, uint vec ) : uint

Combine() публичный Метод

Combines the given CRC32 value with the current running total.

This is useful when using a divide-and-conquer approach to calculating a CRC. Multiple threads can each calculate a CRC32 on a segment of the data, and then combine the individual CRC32 values at the end.

public Combine ( int crc, int length ) : void
crc	int	the crc value to be combined with this one
length	int	the length of data the CRC value was calculated on
Результат	void

Reset() публичный Метод

reset before reuse

public Reset ( ) : void
Результат	void

SlurpBlock() публичный Метод

public SlurpBlock ( byte block ) : void
block	byte
Результат	void

SlurpBlock() публичный Метод

Update the value for the running CRC32 using the given block of bytes. This is useful when using the CRC32() class in a Stream.

public SlurpBlock ( byte block, int offset, int count ) : void
block	byte	block of bytes to slurp
offset	int	starting point in the block
count	int	how many bytes within the block to slurp
Результат	void
