Powershell. Run Command for Every Specific String in Array - powershell

Question

I have a PowerShell command:
Get-AzWebAppAccessRestrictionConfig -ResourceGroupName RG1 -Name CoolTestWebApp1 | Select -ExpandProperty MainSiteAccessRestrictions
That once is ran outputs array:
RuleName : IP-1
Description :
Action : Allow
Priority : 1
IpAddress : 10.0.0.0/24
SubnetId :
RuleName : IP-2
Description :
Action : Allow
Priority : 2
IpAddress : 10.0.0.1/24
SubnetId :
How can I run a command for every entry in RuleName?
For example, something like:
Get-AzWebAppAccessRestrictionConfig -ResourceGroupName RG1 -Name CoolTestWebApp1 | Select -ExpandProperty MainSiteAccessRestrictions | ForEach-Object { Write-Host $RuleNameX }
That would execute:
Write-Host $RuleName1
Write-Host $RuleName2
Which in turn would output:
IP-1
IP-2

Answer 1

You pretty much had it:
Get-AzWebAppAccessRestrictionConfig -ResourceGroupName RG1 -Name CoolTestWebApp1 | Select -ExpandProperty MainSiteAccessRestrictions | ForEach-Object { Write-Host $_.RuleName }
Within a ForEach-Object, you can access the current objects attributes using $_.
i.e
ForEach-Object { $_.attributeName }
If the RuleName attribute contains an array of values, you could then iterate over them too:
$siteRestrictions = (Get-AzWebAppAccessRestrictionConfig -ResourceGroupName RG1 -Name CoolTestWebApp1).MainSiteAccessRestrictions
# Loop through objects
foreach($item in $siteRestrictions) {
# Loop through each RuleName
foreach($ruleName in $item.RuleName) {
# Do some logic here
}
}
