从SFTP站点下载两个文件[重复]

Question

我正在使用 .NET 4.5，我需要连接到 SFTP 站点并将两个文件下载到我的本地电脑。根据我在互联网上的阅读，我没有可以在 .NET 中使用的内置库。

是否有任何我可以使用的可靠的 3rd 方也有简单的示例？

我有以下

username: myusername
password: mypassword
hostname: fts-sftp.myhost.com
protocol: SFTP
Port: 6621

更新

我有下面的代码，但是我在“sftp.Connect()”行收到以下错误消息。

System.dll 中出现“System.Net.Sockets.SocketException”类型的未处理异常

附加信息：连接尝试失败，因为连接方在一段时间后没有正确响应，或者连接失败，因为连接的主机没有响应

检查了提供给我的信用证，以确保我没有错字。

using Renci.SshNet;
using Renci.SshNet.Common;
using Renci.SshNet.Sftp;

namespace SftpExample2
{
    class Program
    {
        static void Main(string[] args)
        {

            string host = "fts-sftp.myaddress.com";
            string password = "mypassword";
            string username = "myusername";
            string remoteDirectory = ".";
            int port = 6671;

            using (SftpClient sftp = new SftpClient(host, port, username, password))
            {
                sftp.Connect();

                var files = sftp.ListDirectory(remoteDirectory);

                foreach (var file in files)
                    Console.WriteLine(file.FullName);

                sftp.Disconnect();
             };

        }
     }
 }

我一般用Renci.SshNet 下面是一个下载示例，更改它以进行下载应该很简单。 我从一个旧项目中提取了它，它可能需要一些调整才能让它编译/运行

static public void UploadFiles(string [] files)
    {
        string host = " fts-sftp.myhost.com";
        string userName = "user";
        string password = "pass";

        var keyboardAuthMethod = new KeyboardInteractiveAuthenticationMethod(userName);
        keyboardAuthMethod.AuthenticationPrompt += delegate(Object senderObject, AuthenticationPromptEventArgs eventArgs)
        {
            foreach (var prompt in eventArgs.Prompts)
            {

                if (prompt.Request.Equals("Password: ", StringComparison.InvariantCultureIgnoreCase))
                {
                    prompt.Response = password;

                }

            }

        };

        var passwordAuthMethod = new PasswordAuthenticationMethod(userName, password);
        var connectInfo = new ConnectionInfo(host, userName, passwordAuthMethod, keyboardAuthMethod);

        using (SftpClient serverConnection = new SftpClient(connectInfo))
        {
            try
            {
foreach (var file in files)
{
    if (!file.Name.StartsWith("."))
    {
        string remoteFileName = file.Name;
        if (file.LastWriteTime.Date == DateTime.Today)

        Console.WriteLine(file.FullName);

        File.OpenWrite(localFileName);

        string sDir = @"localpath";

        Stream file1 = File.OpenRead(remoteDirectory + file.Name);
        sftp.DownloadFile(remoteDirectory, file1);
    }
                serverConnection.Disconnect();
            }
            catch (Exception e)
            {
                throw e;
            }
        }

    }

    using Tamir.SharpSsh;
    public void DownloadSFTP_Files()
    {
        string _ftpURL = "URLHERE";
        string _SftpUserName = "USERNAMEHERE";
        string _SftpPassword = "PASSWORDHERE";
        int _port = 22;
        Sftp oSftp = new Sftp(_ftpURL, _SftpUserName, _SftpPassword);
        oSftp.Connect(_port);
        string path = "";
        // Get List of Files in the SFTP Directory
        System.Collections.ArrayList GetFiles_List = oSftp.GetFileList(path);
        // Download the Files Form SFTP Server to you Local system
        string ServerPath= "SERVERDiRECTORYPATHHERE";
        string LocalPath= "LOCALDiRECTORYPATHHERE";
        oSftp.Get(ServerPath, LocalPath);
        oSftp.Close();
    }
