GetByteCount

public override int GetByteCount(string hexString)

result = hexEncoding.GetByteCount(hexString)

When overridden in a derived class, calculates the number of bytes produced by encoding the characters in the specified String.

hexString

The String containing the set of characters to encode.

Rückgabe: The number of bytes produced by encoding the specified characters.

GetByteCount

public override int GetByteCount(char[] chars, int index, int count)

result = hexEncoding.GetByteCount(chars, index, count)

When overridden in a derived class, calculates the number of bytes produced by encoding a set of characters from the specified character array.

chars

The character array containing the set of characters to encode.

index

The index of the first character to encode.

count

The number of characters to encode.

Rückgabe: The number of bytes produced by encoding the specified characters.

GetBytes

public override int GetBytes(char[] chars, int charIndex, int charCount, byte[] bytes, int byteIndex)

result = hexEncoding.GetBytes(chars, charIndex, charCount, bytes, byteIndex)

When overridden in a derived class, encodes a set of characters from the specified character array into the specified byte array.

chars

The character array containing the set of characters to encode.

charIndex

The index of the first character to encode.

charCount

The number of characters to encode.

bytes

The byte array to contain the resulting sequence of bytes.

byteIndex

The index at which to start writing the resulting sequence of bytes.

Rückgabe: The actual number of bytes written into .

GetBytes

public override byte[] GetBytes(string hexString)

result = hexEncoding.GetBytes(hexString)

Creates a byte array from the hexadecimal string. Each two characters are combined to create one byte. First two hexadecimal characters become first byte in returned array. Non-hexadecimal characters are ignored.

hexString

string to convert to byte array

Rückgabe: byte array, in the same left-to-right order as the hexString

GetBytes

public static byte[] GetBytes(char[] chars, int charIndex, int charCount, int discarded)

result = HexEncoding.GetBytes(chars, charIndex, charCount, discarded)

Creates a byte array from the hexadecimal string. Each two characters are combined to create one byte. First two hexadecimal characters become first byte in returned array. Non-hexadecimal characters are ignored.

chars

The character array containing the set of characters to encode.

charIndex

The index of the first character to encode.

charCount

The number of characters to encode.

discarded

number of characters in string ignored.

Rückgabe: byte array, in the same left-to-right order as the hexString.

GetCharCount

public override int GetCharCount(byte[] bytes, int index, int count)

result = hexEncoding.GetCharCount(bytes, index, count)

When overridden in a derived class, calculates the number of characters produced by decoding a sequence of bytes from the specified byte array.

bytes

The byte array containing the sequence of bytes to decode.

index

The index of the first byte to decode.

count

The number of bytes to decode.

Rückgabe: The number of characters produced by decoding the specified sequence of bytes.

GetChars

public override int GetChars(byte[] bytes, int byteIndex, int byteCount, char[] chars, int charIndex)

result = hexEncoding.GetChars(bytes, byteIndex, byteCount, chars, charIndex)

When overridden in a derived class, decodes a sequence of bytes from the specified byte array into the specified character array.

bytes

The byte array containing the sequence of bytes to decode.

byteIndex

The index of the first byte to decode.

byteCount

The number of bytes to decode.

chars

The character array to contain the resulting set of characters.

charIndex

The index at which to start writing the resulting set of characters.

Rückgabe: The actual number of characters written into .

GetMaxByteCount

public override int GetMaxByteCount(int charCount)

result = hexEncoding.GetMaxByteCount(charCount)

When overridden in a derived class, calculates the maximum number of bytes produced by encoding the specified number of characters.

charCount

The number of characters to encode.

Rückgabe: The maximum number of bytes produced by encoding the specified number of characters.

GetMaxCharCount

public override int GetMaxCharCount(int byteCount)

result = hexEncoding.GetMaxCharCount(byteCount)

When overridden in a derived class, calculates the maximum number of characters produced by decoding the specified number of bytes.

byteCount

The number of bytes to decode.

Rückgabe: The maximum number of characters produced by decoding the specified number of bytes.

HexToByte

private static byte HexToByte(string hexString)

result = HexEncoding.HexToByte(hexString)

Converts 1 or 2 character string into equivalant byte value

hexString

1 or 2 character string.

Rückgabe: byte

IsHexDigit

public static bool IsHexDigit(char c)

result = HexEncoding.IsHexDigit(c)

Returns true is c is a hexadecimal digit (A-F, a-f, 0-9)

c

Character to test.

Rückgabe: true if hex digit, false if not.
