How does -contains work?
Why is this false?

[26] PS I:\>(1,2),3 -contains (1,2)
False

I think this should be True...

RE: How does -contains work?
Probably the same type of problem with the -eq operator:

[19] PS I:\>(1,2),3 -eq 1,2
[20] PS I:\>1,2 -eq 1,2

Both give null.

To be more accurate, both return a zero length array.

So, I'll assume you are trying to compare arrays of numbers?

I don't know if the comparison operators were meant to do that...

The "-contains" lookup solitary value in array.
You may try this:
((1,2,3),(1,2),3)|?{[string]$_ -eq '1 2'}
