PowerShell ForEach Loop Question

Need help writing a PowerShell loop.
I have the following code already, and it works except for the first item. I end up with a "," (comma) to start, which I don't want.
Also there cannot be a "," (comma) at the end, the last path cannot have anything after it.

    ForEach ($tmp in $DependenciesList) {
		$Dependencies += "," + $tmp.FullName
        }

Open in new window

$DependenciesList is an array of file path objects obtained by code previously in my script that populates the array from what it finds.
$Dependencies becomes a string made up of these paths separated by a comma.

I need each path to be separated by a comma (no spacing) and no comma at the very end.
For example, I need the output to look something like this:

C:\Path1\SubPath1,C:\Path2\SubPath2,C:\Path3\SubPath3, ... ,C:\PathX\SubPathX

Open in new window

How can I modify this ForEach loop?

$i =0
ForEach ($tmp in $DependenciesList) {
	if ($i -eq 0){$dependencies += $tmp.fullname}
       else{$Dependencies += "," + $tmp.FullName}
       $i++
        }

Open in new window

Should cover it.

Don't use a loop at all, there is a simple expression doing the necessary:

$Dependencies = $DependenciesList -join ','

Qlemo, that is a great suggestion....but I need the results to be the "FullName" property of each object in the array.
Hence the use of "$tmp.FullName" in the original code.

Any way to do this using your method?

Thanks.

Both solutions would solve my problem.
I went with the "-join" solution since it is simpler/modern code.

Thanks.
