public class ByteBufferInfo

Methods

ExtractDelimitedByteArray(byte[], int, byte[], byte[])

Extracts a byte array that is delimited by two byte array patterns

Declaration

public static byte[]? ExtractDelimitedByteArray(byte[] SrcArray, int StartIndex, byte[] FirstPattern, byte[] SecondPattern)

Parameters

Type	Name	Description
byte[]	SrcArray	The input source array
int	StartIndex	The stating index in the source array
byte[]	FirstPattern	The first byte pattern
byte[]	SecondPattern	The second byte array

Returns

Type	Description
byte[]	Returns a new byte array if there is one between the FirstPattern and the SecondPattern or null if the FirstPattern and the SecondPattern are not found

FindFirstBytePattern(byte[], int, byte[])

Finds the first occurrence of byte array pattern within an array.

Declaration

public static int FindFirstBytePattern(byte[] SrcArray, int StartIndex, byte[] BytePattern)

Parameters

Type	Name	Description
byte[]	SrcArray	Array to search in.
int	StartIndex	Index to start looking at
byte[]	BytePattern	Array of bytes containing the pattern to search for.

Returns

Type	Description
int	The index within the search array of the start of the pattern to search for. Returns -1 if the pattern is not found.

FindLastBytePattern(byte[], int, byte[])

Finds the last occurrence of byte array pattern within an array.

Declaration

public static int FindLastBytePattern(byte[] SrcArray, int LastSrcIndex, byte[] BytePattern)

Parameters

Type	Name	Description
byte[]	SrcArray	Array to search in.
int	LastSrcIndex	Last index in the source array to include in the search range
byte[]	BytePattern	Array of bytes containing the pattern to search for.

Returns

Type	Description
int	The index within the search array of the start of the pattern to search for. Returns -1 if the pattern is not found.

GetStringPosition(byte[], int, int, string, string?)

Searches a binary buffer for a string up until a specified end string.

Declaration

public static int GetStringPosition(byte[] buffer, int startPosition, int endPosition, string find, string? end)

Parameters

Type	Name	Description
byte[]	buffer	The byte array to search for an instance of the specified string.
int	startPosition	The position in the array that the search should be started from.
int	endPosition	An index that if reached indicates the search should be halted.
string	find	The string that is being searched for.
string	end	If the end string is found the search is halted and a negative result returned.

Returns

Type	Description
int	The start position in the buffer of the requested string or -1 if not found.

HasString(byte[], int, int, string, string)

Tests to see if a binary array contains a string.

Declaration

public static bool HasString(byte[] buffer, int startPosition, int endPosition, string find, string end)

Parameters

Type	Name	Description
byte[]	buffer	The byte array to search for an instance of the specified string.
int	startPosition	The position in the array that the search should be started from.
int	endPosition	An index that if reached indicates the search should be halted.
string	find	The string that is being searched for.
string	end	If this string is not null and is found before the find string is found, then false is returned.

Returns

Type	Description
bool	Returns true if the array contains the specified string or false if it does not
