Powershell - ForEach statement - concatenate results - powershell

Question

I'm hoping to get some help from anyone here regarding powershell scripting.
I'm trying to see if there's a way to call all the results of the ForEach statement:
ForEach ($file in $test) {
$filepath = $path+"\"+$file
write-host $filepath
}
the write-host $filepath inside the ForEach statement returns the following:
c:\....\file1.txt
c:\....\file2.txt
c:\....\file3.txt
etc...
i'm trying to see if i can get all those results and put them into 1 line that i can use outside of the foreach statement. sort of like:
c:\....\file1.txt, c:\....\file2.txt, c:\....\file3.txt etc
right now, if i use write-host $filepath outside of the ForEach statement, it only gives me the last result that $filepath got.
hope i made sense.
thank you in advance.

Answer 1

Nothing easier than that ... ;-)
$FullPathList = ForEach ($file in $test) {
Join-Path -Path $path -ChildPath $file
}
$FullPathList -join ','
First you create an array with the full paths, then you join them with the -join statement. ;-)

Answer 2

Another variant,
$path = $pwd.Path # change as needed
$test = gci # change as needed
#(ForEach ($file in $test) {
$path + "\" + $file
}) -join ", "

Answer 3

You might also want to get a look at the FullName property of Get-ChildItem.
If you do (gci).FullName (or maybe gci | select FullName) you'll directly get the full path.
So if $test is a gci from C:\some\dir, then $test.FullName is the array you are looking for.
