powershell ip address csv file - csv

Question

I am trying to dump the contents of only the live adapters to a csv file, for later importing.
The issue was the usage of $_. below.
$colNicConfigs = Get-WMIObject Win32_NetworkAdapterConfiguration | where { $_.IPEnabled -eq "TRUE" }
#loop over each adapter
foreach ($objNicConfig in $colNicConfigs)
{
$objnic=Get-WMIObject Win32_NetworkAdapter | where {$_.deviceID -eq "$objNicConfig.Index" }
#$strname=$objnicconfig.description.split(":")[0]
#replace strname above when testing against actual server since no dot1q defined on my wks
$strname="MGMT:Something"
$connid=$_.NetworkConnectionID
$ipaddr=$_.IPAddress(0)
$ipsm=$_.IPSubnet(0)
$dg=$_.DefaultIPGateway
}
# create dictionary entries
$report = #()
$report += New-Object psobject -Property #{Name=$strname;ConnID=$connid;IP=$ipaddr;SM=$ipsm;DG=$dg}
$report | export-csv .\nic.csv

Your initial issues are the use of "$underscore" within your foreach loop. If you want to reference properties of the $objNicConfig you will use that in place of the "$underscore". So instead of $connid=$_.networkConnectionID you would use $connid=$objNicConfig.networkConnectionID
Also IpAddress and IPSubnet are not methods they are properties, so dropping the (0) will return the write info. If your NIC has multiple IPs I cannot attest to how this will display as my machine does not, that I'm testing on.
Other things I see is that you will need to nest another foreach loop in there in order to reference both WMI namespaces...so something like:
$colNicConfigs = Get-WMIObject Win32_NetworkAdapterConfiguration | where { $_.IPEnabled -eq "TRUE" }
foreach ($objNicConfig in $colNicConfigs)
{
foreach($objnic in (gwmi win32_networkadapter | where {$_.DeviceID -eq $objNicConfig.Index}))
{
$strName = "MGMT:Something"
$objNicConfig.NetworkConnectionID
$objNicConfig.IpAddress
$objNic.IPSubnet
$objNicConfig.DefaultIPGateway
}
}
The above code is what I used to return info on the NICs of my computer.
Now with the "dictionary entries" section. You will not be able to reference the variables within your foreach loop in the manner of adding a psobject. You are only going to capture the last one found within the foreach loop code. If you want to first collect the information in your foreach loop and then use it later down in your script I would suggest looking at hash tables for this.
