How to login FTP with blank password in C #?

For some reason, I need to log into the FTP server with a blank / blank / no password.
It should be pretty simple. Here is the code:

try
{
    FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://xxx.xxx.xxx.xxx/folder/file.csv");

    request.Credentials = new NetworkCredential("VTIE", "");
    request.Method = WebRequestMethods.Ftp.DownloadFile;

    FtpWebResponse response = (FtpWebResponse)request.GetResponse();

    Stream responseStream = response.GetResponseStream();
    StreamReader reader = new StreamReader(responseStream);
    StreamWriter writer = new StreamWriter(@"D:\\text.txt");
    writer.Write(reader.ReadToEnd().ToString());

    writer.Close();
    response.Close();

}
catch (Exception ex)
{
    MessageBox.Show(ex.Message);
}

      

        
        
        
      

    

However, this results in an error message:

The remote server returned an error: (500) syntax error, command unrecognized.

Network trace log:

So USER

there is a command after the command PASS

, but it is rejected with "Syntax Error". What's going on here? How can I use a class FtpWebRequest

with an empty password?

I am using FileZilla FTP client to connect. Here is the log:
