How can I loop into the 2D grid decision tree in C #?

Question

I have a list of objects on which I should set a property based on two criteria, a 2D mesh looks like this:

Property 2\Property 1   B<80        80<B<100       100<B<120           B>120
A < 100                 None          Red           Orange            Orange
100 < A < 120           None          Red           Orange             Green
120 < A < 140           None          Red           Green              Green
140 < A                 None         Orange         Green              Green

Is there a good way to create property 1 and property 2 to dynamically determine the property of an object? It is possible that in the future we will add some criteria, and I think that doing several ifs is not a good solution. I am trying to avoid redundant code.

thank

Answer 1

2 A B 0-3:
A < 100 → Ascale = 0
, A < 120 → Ascale = 1
.. B:
B < 80 → Bscale = 0
, B < 100 → Bscale = 1
.

2d :
out = arrayname [Ascale] [Bscale];
