TgenSerializer is a simple serializer for CSharp (dotnet standard 2.0). The library also includes a few utility classes for work with byte array (byte[])

It makes an object graph of serializeable objects then returns the result as Bytes or into a stream.

A a = new A()
{
    a = 5,
    b = 10,
    name = "foo"
};
TgenFormatter formatter = new TgenFormatter();
Bytes b = formatter.Serialize(a);
byte[] data = b.Buffer; //Can be converted to byte[]
A ret = formatter.Deserialize<A>(data);

[Serializable]
class A { public int a; public int b; public string name; }

*Custom types must be marked using the [Serializable] attribute or implement ISerializable

The Bytes class is a tool that works much like string but for byte arrays. It's used to make the work with arrays of byte arrays easier and simpler. (Like pythons')

With the Bytes class you can use addition (+) to concat arrays of bytes. It also includes implicit cast operations to easily cast primitive objects into bytes and back.
Example:

Bytes hello = "Hello ";
byte[] world = (Bytes)"world";
byte[] helloWorld = hello + world;

Bytes result = helloWorld;
Console.WriteLine(result.ToString()); //'Hello world' casted back to string

Much like StringBuilder but for bytes

BytesBuilder b = new BytesBuilder();
b.Append(5, 10, 20);
b.Append(30);
byte[] nums = b.ToBytes();

Bytes has helper methods to easily convert into groups of primitive values and back

Bytes vals = Bytes.GetBytes(10, 20, 40, 80);
(int n10, int n20, int n40, int n80) = vals.GetTuple<(int, int, int, int)>();
