Syntax

public static class BufferTools

Methods

ByteArrayToHexString(Byte[], Int32, Int32)

Converts a byte array (for example 0xA0, 0x34, 0x05, 0xBF, 0x22, 0x02, 0xE1) to a hex string ("A03405BF2202E1")

Declaration

public static string ByteArrayToHexString(byte[] src, int start = 0, int length = 0)

Parameters

Type	Name	Description
System.Byte[]	src	Byte array to convert
System.Int32	start	Start point in the byte array (default 0)
System.Int32	length	Number of bytes to convert (defaults to the whole array)

Returns

Type	Description
System.String	The string containing the hex representation of the array contents, or null if an error occurred

HexStringToByteArray(String, Int32, Int32)

Converts a hex string (for example "A03405BF2202E1") to a byte array {0xA0, 0x34, 0x05, 0xBF, 0x22, 0x02, 0xE1}

Declaration

public static byte[] HexStringToByteArray(string src, int start = 0, int length = 0)

Parameters

Type	Name	Description
System.String	src	Hex string containing the data to convert
System.Int32	start	Start point in the string (default 0)
System.Int32	length	Length of the string to convert (defaults to the whole string)

Returns

Type	Description
System.Byte[]	Byte array containing the parsed data, or null if the conversion fails

StringToByteArray(String, out Byte[], Int32, Int32, Int32)

Converts a numeric string to a byte array. This can be in hex, for example "A03405BF2202E1" to {0xA0, 0x34, 0x05, 0xBF, 0x22, 0x02, 0xE1} or it can be decimal, for example "304980120183" to {30, 49, 80, 12, 01, 83}

Declaration

public static bool StringToByteArray(string src, out byte[] result, int start = 0, int length = 0, int numberBase = 16)

Parameters

Type	Name	Description
System.String	src	Hex string containing the data to convert
System.Byte[]	result	Byte array containing the parsed data, if successful
System.Int32	start	Start point in the string (default 0)
System.Int32	length	Length of the string to convert (defaults to the whole string)
System.Int32	numberBase	Base of the number encoding in the string. Use 16 to decode hex, 10 to decode decimal. Default is 16.

Returns

Type	Description
System.Boolean	True on success, false otherwise
