Loop X number of times

Here is a simple way to loop any number of times in PowerShell.

It is the same as the for loop above, but much easier to understand for newer programmers and scripters. It uses a range, and foreach. A range is defined as:

range = lower..upper

or

$range = 1..10

A range can be used directly in a for loop as well, although not the most optimal approach, any performance loss or additional instruction to process would be unnoticeable. The solution is below:

foreach($i in 1..10){
    Write-Host $i
}

Or in your case:

$ActiveCampaigns = 10
foreach($i in 1..$ActiveCampaigns)
{
    Write-Host $i
    If($i==$ActiveCampaigns){
        // Do your stuff on the last iteration here
    }
}

This may be what you are looking for:

for ($i=1; $i -le $ActiveCampaigns; $i++)
{
  $PQCampaign     = Get-Variable -Name "PQCampaign$i"     -ValueOnly
  $PQCampaignPath = Get-Variable -Name "PQCampaignPath$i" -ValueOnly

  # Do stuff with $PQCampaign and $PQCampaignPath
}

Use:

1..10 | % { write "loop $_" }

Output:

PS D:\temp> 1..10 | % { write "loop $_" }
loop 1
loop 2
loop 3
loop 4
loop 5
loop 6
loop 7
loop 8
loop 9
loop 10
