c# - 使用SSH.NET和C#复制或移动远程文件

我知道我可以使用SSH.NET库的SftpClient类从SFTP服务器上载文件或从SFTP服务器下载文件，但是我不确定该类如何用于在SFTP服务器上复制或移动远程文件。我也没有在互联网上找到相关 Material 。如何使用SSH.NET库和C#将远程文件从目录A复制或移动到目录B。

更新:
我还尝试使用以下代码尝试SshClient类，但它什么也不做，既没有错误也没有任何异常。

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();
}

在Visual Studio控制台上，我得到以下输出。

可以使用SSH.NET库完成移动远程文件的操作。在这里可用:https://github.com/sshnet/SSH.NET

这是将第一个文件从一个源文件夹移动到另一个源文件夹的示例代码。根据FTP设置在类中设置私有(private)变量。

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;
    }

}
