Make a match between 2 lists

[Marisa_Ontiveros1 (Marisa Ontiveros)]

I have a list variable with an array of elements intallationList{“12345”,“3456”, “3456”} and another array variable excluded{“3452”}.

I need to do a match between the 2, that is, it tells me if excluded exists in the list or not.

[ppr (Peter Preuss)]

list2.Except(list1).toList | or toArray will return all List2 items which are not present in list 1

Not list2.Except(list1).Any() -
True all L2 was present in L1,
False there were some L2 not in L1

Visuals:

And for a check that all L2 are present in L1 we can do:

Thank you very much!!!
