Provides support for reading and writing values in Concise Binary Object Representation (CBOR) format, as originally defined in IETF RFC 7049.

Key Features

  • Reader and writer types for the CBOR format.
  • Built-in support for different CBOR conformance modes.

How to Use

Write and read primitives:

using System.Formats.Cbor;

var cborWriter = new CborWriter(CborConformanceMode.Lax);
cborWriter.WriteTextString("Hello World");

var cborReader = new CborReader(cborWriter.Encode(), CborConformanceMode.Lax);
// Hello World

Write and read an array:

var cborWriter = new CborWriter(CborConformanceMode.Lax);
for (var index = 0; index < 5; index++)

var cborReader = new CborReader(cborWriter.Encode(), CborConformanceMode.Lax);
var arrayLength = cborReader.ReadStartArray();
for (var index = 0; index < arrayLength; index++)
// 01234

Inspect writer and reader state:

var cborWriter = new CborWriter(CborConformanceMode.Lax);
// 10
// True

var cborReader = new CborReader(cborWriter.Encode(), CborConformanceMode.Lax);
// 10
// SomeArray
// 0
