Thanks for your reply @Christian. Tried your steps, copy pasting bits and pieces into the shell and it indeed worked. However If i run the full .ps1 script is not printing out anything.
I've run the script in Powershell IDE setting breakpoints inside the ShowAdapters function, and $netAdapterListParam
has indeed the expected custom objects array I'm passing in, so I've narrowed down the issue to be in the FL commandlet.
For some reason $netAdapterList | fl Name, DeviceName, Guid, SharingEnabled
did not work for me, so I ended up using the following instead:
$formatted = $netAdapterListParam | fl Name, DeviceName, Guid, SharingEnabled | Out-String
Write-Host $formatted
That did the trick and the 4 properties were printed on the screen.
Lessons learned:
1) The Powershell IDE built into Win7 can be a very useful tool for debugging scripts 2) Format-List can be quirky when formatting custom objects, so Out-String was required.
