我尝试上传文件并在 FluentFTP 的帮助下编写了以下代码：

      clientFluentFTP = new FtpClient(hostname,
                                       username,
                                       password);

      clientFluentFTP.LoadProfile(new FtpProfile
      {
        Host = hostname,
        Credentials = new NetworkCredential(username, password),
        Encryption = FtpEncryptionMode.Explicit,
        Protocols = SslProtocols.Tls12,
        DataConnection = FtpDataConnectionType.PASV, 
        Encoding = Encoding.UTF8,
      }) ;

      clientFluentFTP.ValidateAnyCertificate = true;
      clientFluentFTP.Connect();
      clientFluentFTP.UploadFile(localfile, requestname, FtpRemoteExists.Overwrite,false,FtpVerify.Throw);

我用我的第一个文件（UTF8 编码）进行测试，结果是一个零字节文件。没有抛出异常，所以我假设它能够验证转移。显然，传输没有正确关闭。是的，使用命令行 FTP 客户端，我可以毫无问题地传输文件。没有消息，没有错误。只是一个零字节文件。

我做错了什么？

代码中的日志如下。

啊...默认设置是二进制，应该是ascii。所以我补充说：

  clientFluentFTP.UploadDataType = FtpDataType.ASCII;

问题已解决。请参阅问题描述下的评论

它与编码无关。由于配置问题，我更改了提供程序，问题消失了。
