Please don't complain about how a kata was ranked, it's pointless. Reranking a kata strained the server so much that the site was mostly down, so it was disabled.

It is OLD, a lot of the older ones are like that.

As others have mentioned before, this really does not feel like a 5 kyu at all. In its current state, I'd rank it at 7 kyu.

I don't think I understand what you're getting at.
The random tests are present and they generate Assert.AreEqual() statements that are equivalent to the JS ones.
Perhaps you are referring to each of the random test cases not being listed individually in the test runner output?
What do you even mean by 'real' C# code? I'm new to codewars and more than happy to learn if the criticism is constructive, but this isn't a constructive or sufficiently informative comment.

What happened to your random tests?
You cannot translate languages "one-to-one" :/

Could you please change your tests for the better please? :)
You know, more like 'real' C# code? :)

This kata is very unclear.

Approved
