powershell : command does not work when called inside a loop - powershell

Question

The following command does work in a powershell console
Restore-SvnRepository D:\temp\Backup\foo.vsvnbak
(Restore-SvnRepository is a command that comes with visualsvn, it expects a path or unc to a file to be restored as parameter)
As I need to execute this command for a large number of files (>500) I embedded it inside a powershell loop but then it doesn't work
$fileDirectory = "D:\temp\Backup"
$files = Get-ChildItem $fileDirectory -Filter "*.vsvnbak"
foreach($file in Get-ChildItem $fileDirectory)
{
$filePath = $fileDirectory + "\" + $file;
# escape string for spaces
$fichier = $('"' + $filepath + '"')
# write progress status
"processing file " + $fichier
# command call
Restore-SvnRepository $fichier
}
Write-Host -NoNewLine 'Press any key to continue...';
$null = $Host.UI.RawUI.ReadKey('NoEcho,IncludeKeyDown');
I don't understand why this does not work. The loop and filename looks good but when executed, each command throws the following error message
Restore-SvnRepository : Parameter 'BackupPath' should be an absolute or UNC path to the repository
backup file you would like to restore: Invalid method Parameter(s) (0x8004102F)
Could you help me?
EDIT
It looks like that I was confused by Get-ChildItem that return a System.IO.FileSystemInfo rather than a string.
I didn't notice because of a implicit call to the ToString() when writing to the console that made me think I was dealing with string (rather than FSI)
The following code works
$fileDirectory = "D:\temp\Backup\"
$files = Get-ChildItem $fileDirectory -Filter "*.vsvnbak"
foreach($file in $files)
{
# $file is an instance of System.IO.FileSystemInfo,
# which contains a FullName property that provides the full path to the file.
$filePath = $file.FullName
Restore-SvnRepository -BackupPath $filePath
}

Answer 1

$file isn't a string, it's an object containing file data.
You can simplify your code as follows:
$fileDirectory = "D:\temp\Backup"
$files = Get-ChildItem $fileDirectory -Filter "*.vsvnbak"
foreach($file in $files)
{
# $file is an instance of System.IO.FileSystemInfo,
# which contains a FullName property that provides the full path to the file.
$filePath = $file.FullName
# ... your code here ...
}
