Почему Activity.Id имеет два ведущих 0 и конечный 01? ⇐ C#

[Гость]

Код: Выделить всё

using (Activity activity = source.StartActivity("demo")) {     Console.WriteLine(activity?.Id); } 

the output is something like

Код: Выделить всё

00-bbd8c75b04cda7f7fe9ee03b54b2d7ba-72dc8c0dc24fc406-01

and it always has two leading 0s and trailing 01, what does those two leading 0s and trailing 01 mean?

also the trace id is

Код: Выделить всё

bbd8c75b04cda7f7fe9ee03b54b2d7ba

, according to the w3c format, trace-id that is 16 bytes. but isn't that

Код: Выделить всё

bbd8c75b04cda7f7fe9ee03b54b2d7ba

32 bytes since it has 32 characters?
