Methods

CanDecode(string)

Determine if we can decode the given string.

public static bool CanDecode(string encoded)

Parameters

Name	Description
encoded string	The Ascii85 string.

Returns

Name	Description
bool	true if we can decode, false if not.

ArgumentNullException	Thrown when one or more required arguments are null.

Decode(string)

Decodes the specified Ascii85 string into the corresponding byte array.

public byte[] Decode(string encoded)

Parameters

Name	Description
encoded string	The Ascii85 string.

Returns

Name	Description
byte[]	The decoded byte array.

Examples

C#

// Encode and decoding using Ascii85Encoding
Ascii85Encoding ascii85 = new Ascii85Encoding();
byte[] data = Enumerable.Range(1, 10).Select(i => (byte)i).ToArray();

// Encode data byte[]
// 0x1 0x2 0x3 0x4 0x5 0x6 0x7 0x8 0x9 0xA
string encoded = ascii85.Encode(data);

// encoded string
// !<N?+\"U52;#mp

// Decode encodes string 
byte[] decoded = ascii85.Decode(encoded);

// decoded byte[]
// 0x1 0x2 0x3 0x4 0x5 0x6 0x7 0x8 0x9 0xA

VB

' Encode And decoding using Ascii85Encoding
Dim ascii85 As New Ascii85Encoding()

Dim data As Byte() = Enumerable.Range(1, 10).[Select](Function(i) CByte(i)).ToArray()

' Encode data byte[]
' 0x1 0x2 0x3 0x4 0x5 0x6 0x7 0x8 0x9 0xA
Dim encoded As String = ascii85.Encode(data)

' encoded string
' !<N?+\"U52;#mp

' Decode encodes string 
Dim decoded() As Byte = ascii85.Decode(encoded)

' decoded byte[]
' 0x1 0x2 0x3 0x4 0x5 0x6 0x7 0x8 0x9 0xA

Encode(byte[])

Encodes the specified byte array in Ascii85.

public string Encode(byte[] bytes)

Parameters

Name	Description
bytes byte[]	The bytes to encode.

Returns

Name	Description
string	An Ascii85-encoded string representing the input byte array.

Examples

C#

// Encode and decoding using Ascii85Encoding
Ascii85Encoding ascii85 = new Ascii85Encoding();
byte[] data = Enumerable.Range(1, 10).Select(i => (byte)i).ToArray();

// Encode data byte[]
// 0x1 0x2 0x3 0x4 0x5 0x6 0x7 0x8 0x9 0xA
string encoded = ascii85.Encode(data);

// encoded string
// !<N?+\"U52;#mp

// Decode encodes string 
byte[] decoded = ascii85.Decode(encoded);

// decoded byte[]
// 0x1 0x2 0x3 0x4 0x5 0x6 0x7 0x8 0x9 0xA
