System.Memory.Data introduces the BinaryData type, a lightweight abstraction for a byte payload. It makes it easy to convert between string, bytes, and stream.

This abstraction can simplify the API surface by exposing a single type instead of numerous overloads or properties. The BinaryData type handles data ownership efficiently, wrapping passed-in bytes when using byte[] or ReadOnlyMemory<byte> constructors or methods, and managing data as bytes when dealing with streams, strings, or rich model types serialized as JSON.

Key Features

  • Lightweight abstraction for byte payload via BinaryData type.
  • Convenient helper methods for common conversions among string, bytes, and stream.
  • Efficient data ownership handling.

How to Use

To/From String:

var data = new BinaryData("some data");

// ToString will decode the bytes using UTF-8
Console.WriteLine(data.ToString()); // prints "some data"

To/From Bytes:

byte[] bytes = Encoding.UTF8.GetBytes("some data");

// Create BinaryData using a constructor ...
BinaryData data = new BinaryData(bytes);

// Or using a static factory method.
data = BinaryData.FromBytes(bytes);

// There is an implicit cast defined for ReadOnlyMemory<byte>
ReadOnlyMemory<byte> rom = data;

// There is also an implicit cast defined for ReadOnlySpan<byte>
ReadOnlySpan<byte> ros = data;

// there is also a ToMemory method that gives access to the ReadOnlyMemory.
rom = data.ToMemory();

// and a ToArray method that converts into a byte array.
byte[] array = data.ToArray();

To/From stream:

var bytes = Encoding.UTF8.GetBytes("some data");
Stream stream = new MemoryStream(bytes);
var data = BinaryData.FromStream(stream);

// Calling ToStream will give back a stream that is backed by ReadOnlyMemory, so it is not writable.
stream = data.ToStream();
Console.WriteLine(stream.CanWrite); // prints false

BinaryData also can be used to integrate with ObjectSerializer. By default, the JsonObjectSerializer will be used, but any serializer deriving from ObjectSerializer can be used.

var model = new CustomModel
    A = "some text",
    B = 5,
    C = true

var data = BinaryData.FromObjectAsJson(model);
model = data.ToObjectFromJson<CustomModel>();
