我正在尝试登录 ftp 服务器。在 C# 中使用以下代码。

FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://ftp-server");

request.Method = WebRequestMethods.Ftp.ListDirectoryDetails;
// This example assumes the FTP site uses anonymous logon.
//request.AuthenticationLevel = System.Net.Security.AuthenticationLevel.MutualAuthRequired;
request.Credentials = new NetworkCredential("userName", "password!#£");
FtpWebResponse response = (FtpWebResponse)request.GetResponse();

但是，当密码包含一些特殊字符时，登录失败。例如（“！”或“£”）？我得到以下异常。

Unhandled Exception: System.Net.WebException: The remote server returned an error: (530) Not logged in.
  at System.Net.FtpWebRequest.SyncRequestCallback(Object obj)
  at System.Net.FtpWebRequest.RequestCallback(Object obj)
  at System.Net.CommandStream.Dispose(Boolean disposing)
  at System.IO.Stream.Close()
  at System.IO.Stream.Dispose()
  at System.Net.ConnectionPool.Destroy(PooledStream pooledStream)
  at System.Net.ConnectionPool.PutConnection(PooledStream pooledStream, Object owningObject, Int32 creationTimeout, Bo
ean canReuse)
  at System.Net.FtpWebRequest.FinishRequestStage(RequestStage stage)
  at System.Net.FtpWebRequest.GetResponse()
  at FtpClientTest.Program.FtpWebRequest()

当密码不包含任何特殊字符时，我没有得到任何异常。

它是什么 ftp 服务器？您可以使用其他程序登录吗？如果是，请使用wireshark比较通过电线的内容。

所以它可能只是ANSI编码，所以尝试

var secureString = new SecureString();
foreach (var b in Encoding.Default.GetBytes("password!#£"))
    secureString.AppendChar((char)b);

request.Credentials = new NetworkCredential("userName", secureString);
