How do I concatenate a string within a loop with PowerShell?

Question

The command

Get-VM | Where {$_.PowerState -eq "PoweredOn"} | Select Name,VMHost | Where {$_ -match "abc" -or $_ -match "def"} | foreach{$_.Name} | Out-File output.txt

writes a list to output.txt where only the column Name will be printed in the form:

a
b
c
...

Now what I want to achieve is to append ,xxx to each line in some sort of loop, so that I get the following:

a,xxx
b,xxx
c,xxx
...

I tried to append the string, but this doesn't seem to work:

Get-VM | Where {$_.PowerState -eq "PoweredOn"} | Select Name,VMHost | Where {$_ -match "abc" -or $_ -match "def"} | foreach{$_.Name} | Out-File output.txt | Add-Content output.txt ",xxx"

I'm really not familiar with PowerShell, and I did not find a way to concatenate ,xxx.

In my case it is essential to do the concatenation within a loop, not with a file operation afterwards.

Instead of foreach { $_.Name }, write foreach { "$($_.Name),xxx" }
