通过C＃.Net发送时的SFTP或FTPS(SFTP or FTPS when sending via C#.Net)

 我读了这篇文章： 
 
 
 
 这两者彼此非常不同，尽管它们都旨在服务于同一目的。 SFTP使用单个通道发送和接收所有相关数据，而FTPS使用另一个动态决定数据的通道。 FTPS在通过防火墙时经常遇到问题，因为它不知道数据正在使用的端口，并且无法允许通过端口的流量。 FTPS以文本格式发送消息，允许人们读取日志并确定会话期间发生的事情。 SFTP无法做到这一点，因为消息不是文本，而是二进制。

 我不想假设任何事情，因为如果我错了，这会让我的工作变得更难，但是当我通过C＃/ .Net4发送文件时，这样： 
 
  var request = (FtpWebRequest) WebRequest.Create(FtpUrl + filename);
    request.Method = WebRequestMethods.Ftp.UploadFile;

    var secureString = new SecureString();
    foreach (var b in Encoding.Default.GetBytes(FtpPassword))
      secureString.AppendChar((char) b);
    request.Credentials = new NetworkCredential(FtpUsername, secureString);
    request.EnableSsl = true;
 
 那是SFTP还是FTPS？ 由于EnableSsl，我假设FTPS正如文章所示。 
 
 如果不是SFTP，我可以将其更改为SFTP吗？ 我在通过防火墙发送时遇到问题。 
 
 谢谢！ 

I read this article:
 
 
 
The two are very different from each other, although they both aim to serve the same purpose. SFTP uses a single channel to transmit and receive all the pertinent data, while FTPS uses another channel that is dynamically decided for the data. FTPS often had problems when passing through a firewall, as it did not know the port that was being used by the data, and failed to allow traffic through the port. FTPS sends messages in a text format, allowing people to read logs and determine what happened during the session. This is not possible with SFTP, as the messages are not in text, but in binary.

I didn't want to assume anything as this would just make my job harder if I am wrong but when I am sending a file through C#/.Net4 like this:
 
  var request = (FtpWebRequest) WebRequest.Create(FtpUrl + filename);
    request.Method = WebRequestMethods.Ftp.UploadFile;

    var secureString = new SecureString();
    foreach (var b in Encoding.Default.GetBytes(FtpPassword))
      secureString.AppendChar((char) b);
    request.Credentials = new NetworkCredential(FtpUsername, secureString);
    request.EnableSsl = true;
 
Is that going SFTP or FTPS? I am assuming FTPS as the article indicates due to the EnableSsl.
 
If it is not SFTP, can I change this to be SFTP instead? I'm having problems sending through a firewall.
 
Thanks!
