Get Value of Array Element (Key/Value Pair)

Okay, I have learned a lot today, but really having an issue with this one. I have created an array using import-csv. It has two columns. I want to use the first column as a key and return the value in the second column.
I am sure, knowing PowerShell, that there is probably a very simple way of doing it, but what I've got now is:
$a = $ClientList | Where-Object client_id -EQ "123" | select client_name
So, if $ClientList contains:
client_id,client_name
111,John Smith
123,Jane Doe
...
I want to populate $a with "Jane Doe"
However, whet I end up with is:
client_name
-----------
Jane Doe
How do I return ONLY "Jane Doe" without the header?

For example like this:
$a = $ClientList | Where-Object client_id -EQ "123" | Select-Object -ExpandProperty client_name

Open in new window

or like that:
$a = ($ClientList | Where-Object client_id -EQ "123").client_name

Open in new window
