會在哪裏FTP別名進入.NET中的FTP連接

Question

我有一個當前的連接方法

ftp ftpClient = new ftp(@"ftp://testftp/", @"username", @"password", false); 
string[] dirlist = ftpClient.directoryListSimple("/"); 
      foreach (var x in dirlist) { Console.WriteLine(x); } 
      Console.ReadKey(); 

這是FTP類的目錄列表

 public class ftp 
    { 
     private string host = null; 
     private string user = null; 
     private string pass = null; 
     private FtpWebRequest ftpRequest = null; 
     private FtpWebResponse ftpResponse = null; 
     private Stream ftpStream = null; 
     private int bufferSize = 2048; 
     private bool enableSSL = true; 
/* List Directory Contents File/Folder Name Only */ 
    public string[] directoryListSimple(string directory) 
    { 
     try 
     { 
      /* Create an FTP Request */ 
      ftpRequest = (FtpWebRequest)FtpWebRequest.Create(host + "/" + directory); 
      /* Log in to the FTP Server with the User Name and Password Provided */ 
      ftpRequest.Credentials = new NetworkCredential(user, pass); 
      /* When in doubt, use these options */ 
      ftpRequest.UseBinary = true; 
      ftpRequest.UsePassive = false; 
      ftpRequest.KeepAlive = true; 
      /* EnableSSL if required, most times false */ 
      ftpRequest.EnableSsl = enableSSL; 
      /* Specify the Type of FTP Request */ 
      ftpRequest.Method = WebRequestMethods.Ftp.ListDirectory; 
      /* Establish Return Communication with the FTP Server */ 
      ftpResponse = (FtpWebResponse)ftpRequest.GetResponse(); 
      /* Establish Return Communication with the FTP Server */ 
      ftpStream = ftpResponse.GetResponseStream(); 
      /* Get the FTP Server's Response Stream */ 
      StreamReader ftpReader = new StreamReader(ftpStream); 
      /* Store the Raw Response */ 
      string directoryRaw = null; 
      /* Read Each Line of the Response and Append a Pipe to Each Line for Easy Parsing */ 
      try { while (ftpReader.Peek() != -1) { directoryRaw += ftpReader.ReadLine() + "|"; } } 
      catch (Exception ex) { Console.WriteLine(ex.ToString()); } 
      /* Resource Cleanup */ 
      ftpReader.Close(); 
      ftpStream.Close(); 
      ftpResponse.Close(); 
      ftpRequest = null; 
      /* Return the Directory Listing as a string Array by Parsing 'directoryRaw' with the Delimiter you Append (I use | in This Example) */ 
      try { string[] directoryList = directoryRaw.Split("|".ToCharArray()); return directoryList; } 
      catch (Exception ex) { Console.WriteLine(ex.ToString()); } 
     } 
     catch (Exception ex) { Console.WriteLine(ex.ToString()); } 
     /* Return an Empty string Array if an Exception Occurs */ 
     return new string[] { "" }; 
    } 
} 

的代碼，然後我嘗試運行目錄列表，這在測試設置中非常完美。
然而，當我去與我們的合作伙伴之一，我得到530未登錄
我在Chrome測試，它的精細記錄並顯示目錄列表
我與SSL試過，不，主動，被動無效
我能想到的最後一件事是他們提供了一個別名，但我不知道它會去哪裏。在谷歌，他們說的做testftp |別名，但沒有因URI格式
任何幫助，將不勝感激

找到我的答案，
出於某種原因，人們試圖建立SSL連接即使我把它設置爲假。註釋掉該行允許連接
