I am currently working on a tool that is supposed to take over the IPv4 configuration, among other things. So far I have automatically determined the current adapter, with several active adapters (e.g. VM adapter at the host) the wrong one is selected.

Is there an elegant and lean solution for this?

`

This shows “‘MSFT_NetAdapter (CreationClassName = “MSFT_NetA….” at the listbox but works fine

$getAdapter = Get-NetAdapter | ? {$_.Status -eq ‘Up’}

$adapterName = $getAdapter.name

foreach ($adapter in $getAdapter) {

$listBox.Items.Add($adapter)

}

This Shows me the Adapter Name in Listbox but the Commands in “try” with $seletedAdapter dont

Work

foreach ($adapter in $adapterName) {

$listBox.Items.Add($adapter)

}

function set-ip {

#... some var





#... validate ip format etc.











$selectedAdapter = $listBox.SelectedItem











$IPParam = @{





    AddressFamily   = $ipType





    IPAddress       = $ipv4





    PrefixLength    = $prefix





    DefaultGateway  = $gateway





}





$DNSParam = @{





    ServerAddresses = @($DNS1, $DNS2)





}





Write-Host "ok select here now"

if ($selectedAdapter) {

try {





    Write-Host "set ip for $selectedAdapter"





    If (($selectedAdapter | Get-NetIPConfiguration).IPv4Address.IPAddress) {





     $selectedAdapter | Remove-NetIPAddress -AddressFamily $ipType -Confirm:$false





    }





    If (($selectedAdapter | Get-NetIPConfiguration).Ipv4DefaultGateway) {





     $selectedAdapter | Remove-NetRoute -AddressFamily $ipType -Confirm:$false





    }











    $selected`your text`Adapter | New-NetIPAddress @IPParam -Confirm:$false





    $selectedAdapter | Set-DnsClientServerAddress @DNSParam -Confirm:$false





    Write-Host "some text"





} catch {





    Write-Warning "some warning text"





    Write-Warning "$_"





}

}

}`
