之前一个项目用到的FTP客户端，支持隐式TLS加密，使用的是AlexPilotti的库 可以通过
public FtpsClient(string server, string remoteUploadPath, string remoteDownLoadPath,
string userID, string password, bool acceptAllCertificate,bool useImpicit)
来指定FTP的连接属性 如果要想访问的FTP站点证书是自签名的，可以直接指定
acceptAllCertificate = true
来跳过证书验证，具体的加密设置在构造函数中也可以修改
