使用WinSCP从FTP下载文件的代码。NET程序集未连接,但我可以在WinSCP GUI中连接

try
{
    SessionOptions sessionOptions = new SessionOptions
    {
        Protocol = Protocol.Ftp,
        HostName = "172.xx.xxx.xx",
        UserName = "usersample",
        Password = "P@ssw0rd",
        PortNumber = 21
    };

    using (Session session = new Session())
    {
        // Connect
        session.Open(sessionOptions);

        // Download files
        TransferOptions transferOptions = new TransferOptions();
        transferOptions.TransferMode = TransferMode.Binary;

        TransferOperationResult transferResult;
        transferResult =
            session.GetFiles(
                "/HST/sample.txt", "C:\\Users\\john\\Documents\\SampleFolder\\",
                false, transferOptions);

        // Throw on any error
        transferResult.Check();

        // Print results
        foreach (TransferEventArgs transfer in transferResult.Transfers)
        {
            Console.WriteLine("Download of {0} succeeded", transfer.FileName);
        }

        Console.ReadLine();
    }

}
catch (Exception e)
{
    Console.WriteLine("Error: {0}", e);
    Console.ReadLine();
}

最初,它具有以下功能:

SshHostKeyFingerprint = "ssh-rsa 2048 xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx"

我已经手动尝试了这些凭据,它们很有效。我可以登录。 请帮忙。非常感谢。
