Syntax

public static class Rlp

Methods

Decode(byte[])

Decodes an RLP-encoded byte array into its constituent data items.

Declaration

public static object[] Decode(byte[] data)

Parameters

Type	Name	Description
byte[]	data	The RLP-encoded byte array to decode.

Returns

Type	Description
object[]	An array of decoded objects, where each element is either a byte array or a nested array of objects.

Exceptions

Type	Condition
FormatException	If the data is not valid RLP: an item's declared length runs past the end of the data, or a length prefix is too long to describe data held in memory.

Encode(params object?[])

RLP-encodes one or more data items into a byte array. A single argument is encoded as that item alone; two or more arguments are encoded as an RLP list. Calling with no arguments produces an empty list (0xC0), and a null array produces 0x80.

Declaration

public static byte[] Encode(params object?[] data)

Parameters

Type	Name	Description
object[]	data	The data items to encode: byte[], ReadOnlyMemory<byte>, string, non-negative int, long, ulong, short, ushort, uint and BigInteger values, decimal values (the fractional part is truncated), null (encoded as an empty string), and nested arrays of these (encoded as lists). Other types, such as byte, sbyte, float and double, are not supported.

Returns

Type	Description
byte[]	The RLP-encoded byte array.

Exceptions

Type	Condition
ArgumentException	If a data item is of an unsupported type.
ArgumentOutOfRangeException	If a numeric data item is negative.
