Loop through multiple array in powershell

I have 2 arrays here one contains the servername and other contains the IP.

I need to loop through them and create a key value pair like below for each server

server1:ip1
server2:ip2

I have written below code, but the problem is if i debug the code using F11, it is working fine, but i don't it gives some error which is different every time.

so feeling like it is not that reliable piece to continue.

    $NewDNSEntryName = $DNSEntryName.Split(",")
    $DNSIPs = $DNSIP.Split(",")


if($DNSEntryName -match "," -or $DNSIP -match ",")
    {   

   0..($NewDNSEntryName.Count - 1) | ForEach-Object {

   $fullName=""
   $fullName += @("$($NewDNSEntryName[$_]):$($DNSIPs[$_])")

This is the line where i am facing trouble

0..($NewDNSEntryName.Count - 1) | ForEach-Object

Please let me know why this code is behaving like this else any alternate idea is appreciated

Assuming each item in each list corresponds with each other exactly, you can use a for loop and loop through the array indexes.

$NewDNSEntryName = $DNSEntryName.Split(",")
$DNSIPs = $DNSIP.Split(",")

for ($i = 0; $i -lt $DNSIPs.count; $i++) {
    "{0}:{1}" -f $NewDNSEntryName[$i],$DNSIPs[$i]
}

For the code above to work, $DNSEntryName and $DNSIP must be single strings with commas between names and IPs. If $DNSEntryName and $DNSIP are already lists or arrays, something else will need to be done.

In your attempt, technically, your logic should work given everything written above is true. However, $fullName is emptied at every single iteration, which may produce undesirable results.
