Powershell $webclient.UploadFile

Question

Hello Community!
I am new to powershell and i have been playing around with getting files to upload using FTP.
I have got it working and i am happy with the results but i would like to get the script to exit if the upload fails and to only move the file if its successful. 
#Files to Send
$Dir="C:\test\Output"
#ftp server
$ftp = "ftp://xxx.xxx.xxx.xxx/"
$user = "User"
$pass = "Password"
$webclient = New-Object System.Net.WebClient
$webclient.Credentials = New-Object System.Net.NetworkCredential($user,$pass)
foreach($item in (dir $Dir "*.csv")){
"Uploading $item..."
$uri = New-Object System.Uri($ftp+$item.Name)
$webclient.UploadFile($uri, $item.FullName)
Move-Item c:\test\Output\*.csv c:\test\Output\copied
can anyone assist please?
Many Thanks in advance :-)

Hi Kallum,
To use try and catch in script, please refer to the script below, please note I haven't tested this script, which can only move files if the .csv has been uploaded via FTP successfully.
In addition, in case of deleting the files by mistake, I have added the "-whatif" to display the files name without deleting the file:
#Files to Send
$Dir="C:\test\Output"
#ftp server
$ftp = "ftp://xxx.xxx.xxx.xxx/"
$user = "User"
$pass = "Password"
$webclient = New-Object System.Net.WebClient
$webclient.Credentials = New-Object System.Net.NetworkCredential($user,$pass)
foreach($item in (dir $Dir"*.csv")){
"Uploading $item..."
try{
$uri = New-Object System.Uri($ftp+$item.Name)
$webclient.UploadFile($uri, $item.FullName)}#end try
catch{
$err=$_
Write-Host $error.exception.message
continue} # using the "continue" to turn to the next loop and ignore the move-item cmdlet
Move-Item $item.fullname c:\test\Output\copied -whatif}
If there is anything else regarding this issue, please feel free to post back.
Best Regards,
