System.String[] - Result - powershell

Question

I did a search and I understand the issue that some of these are arrays. What I am not sure I understand is why I am getting this when I am specifically trying to return just one value.
I am using a ForEach loop and pulling from a text file the names of the computers I want to query.
I want to verify that the IP address I am pinging is the same computer I want to connect to. We have many users on VPN and the DNS doesn't update fast enough. This means we get some incorrect information.
$NIC2 = Get-WmiObject win32_NetworkAdapterConfiguration -ComputerName $computer | Where-Object {$_.DNSDomain -eq "usms.contoso.com"} | Select-Object IPAddress
This should give me only one IP address and not an array, but unfortunately I get the System.String[] in the CSV output. If I just type this command out in the PowerShell command line it works beautifully, but not when I put it into a CSV.
any ideas?
Thanks in advance.
Entire code below - I get the results for everything except the $NIC2 and doing $NIC2.IPAddress[0] doesn't seem to work.
Putting $NIC2[0] just give me this in that column
dapterConfiguration -ComputerName $computer | Where-Object {$_.DNSDomain -eq "contoso.com"} | Select-Object IPAddress

Answer 1

OK - I finally figured it out because I kept going around in circles and getting nowhere.
Thank you to Zett42 who led me in the right direction but I was still failing.
My first problem was that I hadn't identified $NIC2 as an Array which was part of my issue when trying $NIC2[0]. However, even after being Defined as an Array it still didn't work.
I then created another array and did this $NICIP = $NIC2.IPAddress and then output $NICIP[0] which works. Not exactly sure why that works.
Here is the entire code

#Defines the variable and format for Date
$Date = Get-date -UFormat %h_%d_%y_%H%M
#Define the name of the files to output
$OutputFile = "C:\Temp\Verify-Computer-$Date.csv" #All Computers On-Line Status will be provided in this file
#Defines the Array where to put the data and the $Ping variable to store the IP address
$DataArray = #()
$Resolution = New-Object System.Object.NetworkInformation.Ping

$Value = $TESTConnection.PingSucceeded

$NICIP = $NIC2.IPAddress
