I know that I can upload and download files from/to a SFTP server using SftpClient
class of SSH.NET library but I am not sure how can this class be used for copying or moving a remote file on the SFTP server. I also did not find relevant material on internet. How can i copy or move a remote file from directory A to directory B, using SSH.NET library and C#.
Update:
I also tried experimenting with SshClient
class using the below code but it does nothing, neither any error nor any exception.
ConnectionInfo ConnNfo = new ConnectionInfo("FTPHost", 22, "FTPUser",
new AuthenticationMethod[]{
// Pasword based Authentication
new PasswordAuthenticationMethod("FTPUser","FTPPass")
}
);
using (var ssh = new SshClient(ConnNfo))
{
ssh.Connect();
if (ssh.IsConnected)
{
string comm = "pwd";
using (var cmd = ssh.CreateCommand(comm))
{
var returned = cmd.Execute();
var output = cmd.Result;
var err = cmd.Error;
var stat = cmd.ExitStatus;
}
}
ssh.Disconnect();
}
On Visual Studio console, i get the below output.
*SshNet.Logging Verbose: 1 : SendMessage to server 'ChannelRequestMessage': 'SSH_MSG_CHANNEL_REQUEST : #152199'.
SshNet.Logging Verbose: 1 : ReceiveMessage from server: 'ChannelFailureMessage': 'SSH_MSG_CHANNEL_FAILURE : #0'.*
Moving a remote File can be done using SSH.NET library. Available here: https://github.com/sshnet/SSH.NET
Here is sample code to move first file from one source folder to another. Set private variables in the class according to the FTP set up.
using System;
using System.Linq;
using System.Collections.Generic;
using Renci.SshNet;
using Renci.SshNet.Sftp;
using System.IO;
using System.Configuration;
using System.IO.Compression;
public class RemoteFileOperations
{
private string ftpPathSrcFolder = "/Path/Source/";//path should end with /
private string ftpPathDestFolder = "/Path/Archive/";//path should end with /
private string ftpServerIP = "Target IP";
private int ftpPortNumber = 80;//change to appropriate port number
private string ftpUserID = "FTP USer Name";//
private string ftpPassword = "FTP Password";
/// <summary>
/// Move first file from one source folder to another.
/// Note: Modify code and add a for loop to move all files of the folder
/// </summary>
public void MoveFolderToArchive()
{
using (SftpClient sftp = new SftpClient(ftpServerIP, ftpPortNumber, ftpUserID, ftpPassword))
{
SftpFile eachRemoteFile = sftp.ListDirectory(ftpPathSrcFolder).First();//Get first file in the Directory
if(eachRemoteFile.IsRegularFile)//Move only file
{
bool eachFileExistsInArchive = CheckIfRemoteFileExists(sftp, ftpPathDestFolder, eachRemoteFile.Name);
//MoveTo will result in error if filename alredy exists in the target folder. Prevent that error by cheking if File name exists
string eachFileNameInArchive = eachRemoteFile.Name;
if (eachFileExistsInArchive)
{
eachFileNameInArchive = eachFileNameInArchive + "_" + DateTime.Now.ToString("MMddyyyy_HHmmss");//Change file name if the file already exists
}
eachRemoteFile.MoveTo(ftpPathDestFolder + eachFileNameInArchive);
}
}
}
/// <summary>
/// Checks if Remote folder contains the given file name
/// </summary>
public bool CheckIfRemoteFileExists(SftpClient sftpClient, string remoteFolderName, string remotefileName)
{
bool isFileExists = sftpClient
.ListDirectory(remoteFolderName)
.Any(
f => f.IsRegularFile &&
f.Name.ToLower() == remotefileName.ToLower()
);
return isFileExists;
}
}
