在FluentFTP上载零字节文件

问题描述

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);

我测试了我的第一个文件（UTF8编码），结果是一个零字节文件。没有异常被抛出，因此我认为它能够验证传输。显然，传输未正确关闭。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。只是一个零字节的文件。

我该怎么办？

下面是代码中的日志。

解决方法

Ah ...默认设置为二进制，应为ascii。所以我加了：

  clientFluentFTP.UploadDataType = FtpDataType.ASCII;

~~问题已解决。请参阅问题描述下的我的评论~~

它与编码无关。由于配置问题，我更改了提供程序，但问题消失了。
