Looping through each NoteProperty in a custom object - powershell

Question

I'm creating a PSObject in Powershell like this:
$NetworkInfo = New-Object PSObject
$NetworkInfo | Add-Member -type NoteProperty -Name IPAddress -Value "10.10.8.11"
$NetworkInfo | Add-Member -type NoteProperty -Name SubnetMask -Value "255.255.255.0"
$NetworkInfo | Add-Member -type NoteProperty -Name Gateway -Value "10.10.8.254"
$NetworkInfo | Add-Member -type NoteProperty -Name Network -Value "10.10.8.0"
$NetworkInfo | Add-Member -type NoteProperty -Name DNS1 -Value "10.10.10.200"
$NetworkInfo | Add-Member -type NoteProperty -Name DNS2 -Value "10.10.10.201"
$NetworkInfo
I want to do a specific action for each NoteProperty in this PSObject, but I'm not sure how to go about doing that. For example (even though I know it's the wrong way to do it) this code:
ForEach ($noteProperty in $NetworkInfo) {
Write-Host $noteProperty
}
Only outputs the entire object as an array:
#{IPAddress=10.10.8.11; SubnetMask=255.255.255.0; Gateway=10.10.8.254; Network=10.10.8.0; DNS1=10.10.10.200; DNS2=10.10.10.201}
EDIT: Each NoteProperty is of the variable type System.String - if that's pertinent.
Am I creating the object incorrectly, or do I just not understand how to go through the object?

Answer 1

You can use Get-Member as mentioned by Mike; an alternative that keeps the order is to use the PSObject property that is present on all objects:
#View details for all properties on a specific object
$NetworkInfo.PSObject.Properties
#similar code to Mike's, working with name and value:
$NetworkInfo.PSObject.Properties | foreach-object {
$name = $_.Name
$value = $_.value
"$name = $value"
}

Answer 2

This should get you what you need:
$NetworkInfo | get-member -type NoteProperty | foreach-object {
$name=$_.Name ;
$value=$NetworkInfo."$($_.Name)"
write-host "$name = $value"
}

Answer 3

Try:
ForEach ($noteProperty in $NetworkInfo.PSObject.Properties)
{
Write-Host $noteProperty.Name
Write-Host $noteProperty.Value
}

Answer 4

Short (even Faster) version:
$NetworkInfo.psobject.properties.foreach({"$($_.Name) = $($_.Value)"})
Output:
IPAddress = 10.10.8.11
SubnetMask = 255.255.255.0
Gateway = 10.10.8.254
Network = 10.10.8.0
DNS1 = 10.10.10.200
DNS2 = 10.10.10.201
Or another one:
$NetworkInfo.foreach({$_})
Will give you:
IPAddress : 10.10.8.11
SubnetMask : 255.255.255.0
Gateway : 10.10.8.254
Network : 10.10.8.0
DNS1 : 10.10.10.200
DNS2 : 10.10.10.201
You can also select 1 property like:
$NetworkInfo.DNS1
Which will give you:
10.10.10.200
Or select all DNS entries:
$NetworkInfo.foreach({$_}) | Select-Object DNS*
Result:
DNS1 DNS2
---- ----
10.10.10.200 10.10.10.201
Or if you wish:
$NetworkInfo.psobject.properties.where({$_.Name -like 'DNS*' }).Value
Will give:
10.10.10.200
10.10.10.201
Combining foreach and where:
$NetworkInfo.psobject.properties.where({$_.Name -like 'DNS*' }).foreach({
"$($_.Name) = $($_.Value)"})
Wil give:
DNS1 = 10.10.10.200
DNS2 = 10.10.10.201
Transform it into a 2 dimensional array:
$NetworkInfo.psobject.properties.where({$_.Name -like 'DNS*' }).foreach({
,(#([string]$_.Name, [string]$_.Value))})
Do NOT forget the "," in "{,"
Output:
DNS1
10.10.10.200
DNS2
10.10.10.201
Which is two dimensional
$NetworkInfo.psobject.properties.where({$_.Name -like 'DNS*' }).foreach({
,(#([string]$_.Name, [string]$_.Value)) })[0]
DNS1
10.10.10.200
And the following:
$NetworkInfo.psobject.properties.where({$_.Name -like 'DNS*' }).foreach({
,(#([string]$_.Name, [string]$_.Value)) })[0][0]
DNS1
And...
$NetworkInfo.psobject.properties.where({$_.Name -like 'DNS*' }).foreach({
,(#([string]$_.Name, [string]$_.Value)) })[0][1]
10.10.10.200
