Concatenate filenames list with string

I have this script that stores filenames into a text file:

Get-ChildItem -Path "C:\Users\MyUser\Documents\Files" -Name |
  Out-File "C:\Users\MyUser\Documents\Files\FileList.txt"

The result is:

file1.txt
file2.txt
file3.txt
file4.txt

I would like it to produce a list of PowerShell statements in a text file so that I could use them later like this:

Add-Content -Path "C:\Users\MyUser\Documents\Files\file1.txt" -Value "foo"
Add-Content -Path "C:\Users\MyUser\Documents\Files\file2.txt" -Value "foo"
Add-Content -Path "C:\Users\MyUser\Documents\Files\file3.txt" -Value "foo"
Add-Content -Path "C:\Users\MyUser\Documents\Files\file4.txt" -Value "foo"

Is it possible to concatenate a string to the file name the way I need?

I am also not sure whether I understand your question correctly but maybe this is what you are looking for:

Get-ChildItem -Path "C:\Users\MyUser\Documents\Files" | 
    % {
        "Add-Content -Path `"{0}`" -Value `"foo`"" -f $_.FullName
    } | Out-File "C:\Users\MyUser\Documents\Files\FileList.txt"

I'm a little unsure about what you're asking, but if I have it correct you want to get a list of files, add a line to the end of the file, and put the names of the files in text file.

Get-ChildItem -Path "C:\Users\MyUser\Documents\Files" | 
    ForEach-Object {
        $_ | Add-Content -Value "foo"
        $_.Name
    } | Out-File "C:\Users\MyUser\Documents\Files\FileList.txt"

This is one possible way. It passes each item to ForEach-Object, where a value is added to the file, and the file name is sent to the pipeline. That gets piped into Out-File which writes the list.

There are many ways to achieve this; it's best to study and play with pipelining and then look at the various cmdlets and how they handle pipeline input.
