Move files between folders in FTP with different credentials

Amogh Natu

I'm working on a scenario wherein I need to move some files from one FTP location to another. The FTP server is the same but credentials for the source and destination are different.
For example,
I need to copy files
FROM
"ftp://sampleftp.com/sourceFolder" with login credentials "User1", "Password1"
TO
"ftp://sampleftp.com/destinationFolder" with login credentials "user2","password_2"
Kindly note the different credentials I have used above for source and destination.
I referred to this similar stackoverflow question link but that seems to work for the FTP folder with constant login credentials.
Can someone please guide me on how best can I implement this?
Thanks a lot!

No issues, one solution is to save above powershell scripts as .ps1 files and execute these from C#. Refer this

http://www.codeproject.com/Articles/18229/How-to-run-PowerShell-scripts-from-C

the other one is to write your own code what Powershell scripts are doing? [I feel you're duplicating the existing capability by picking this option..]

Tell me which is your choice, and also why?

Hello Sumit,

I apologize for not mentioning in the question. I want to implement this functionality using C# language.

Thanks,
Amogh.

You can use Powershell scripting to do so. Download file using below script:

#ftp server
$ftp = "ftp://sampleftp.com/sourceFolder"
$user = "User1"
$pass = "Password1"
$SetType = "bin"
$remotePickupDir = Get-ChildItem 'c:\test' -recurse
$webclient = New-Object System.Net.WebClient

$webclient.Credentials = New-Object System.Net.NetworkCredential($user,$pass)
foreach($item in $remotePickupDir){
$uri = New-Object System.Uri($ftp+$item.Name)
#$webclient.UploadFile($uri,$item.FullName)
$webclient.DownloadFile($uri,$item.FullName)
}

Use, powershell again to upload:

#we specify the directory where all files that we want to upload
$Dir="C:/Dir"

#ftp server
$ftp = "ftp://sampleftp.com/destinationFolder"
$user = "user2"
$pass = "password_2"

$webclient = New-Object System.Net.WebClient

$webclient.Credentials = New-Object System.Net.NetworkCredential($user,$pass)

#list every sql server trace file
foreach($item in (dir $Dir "*.trc")){
"Uploading $item..."
$uri = New-Object System.Uri($ftp+$item.Name)
$webclient.UploadFile($uri, $item.FullName)
}
