C# Array of anonymous class inside another anonymous class

Question

I deserialize a JSon string that holds an object with an array of subobjects.
The current working solution looks like this:

var definition = new { systems = new subclass[0] };
var ret = JsonConvert.DeserializeAnonymousType(source, definition);

public class subclass
{
    public long id;
}

Is there a way to replace the subclass with another anonymous one?
I tried using the following, but only get a compiler error:

var definition = new { constellations = new{ id=0L }[0] };

Use Dynamic

I wonder if you could do:

var definition = new { systems = MakeEmptyArrayFrom(new { id = 0L}) };
...
static T[] MakeEmptyArrayFrom<T>(T value) => new T[0];

note: if that works, it will probably also work even if you use something like:

static T[] MakeNullArrayFrom<T>(T value) => null;

as I imagine the library is more interested in the Type than the value.

Yes, it works. Even the null version. As I have multiple of these it will help declutter the code
