Filezilla c# 500 Syntax error, command unrecognized

I have created a ftp server using Filezilla. I am trying to upload a single file using c# code. My cide is very simple a functino called upload:

static void UploadFile(string filepath)
    {
     string m_FtpHost = "http://ip:port/";
     string m_FtpUsername = "userID";
     string m_FtpPassword = "pass";
     // Get an instance of WebClient
     WebClient client = new System.Net.WebClient();
     // parse the ftp host and file into a uri path for the upload
     Uri uri = new Uri(m_FtpHost + new FileInfo(filepath).Name);
     // set the username and password for the FTP server
     client.Credentials = new System.Net.NetworkCredential(m_FtpUsername, m_FtpPassword);
     // upload the file asynchronously, non-blocking.

     client.UploadFileAsync(uri, "STOR", filepath);
    }

    static void Main(string[] args)
    {
      UploadFile("file.pdf"); 
      Console.ReadKey();
    }

In the Filezilla server gui I am getting the following messages:

(000017)11/23/2015 10:47:19 AM - (not logged in) (ip)> STOR  /file.pdf HTTP/1.1

Any idea what might be wrong here? EDIT: I tried to change http with ftp in the UploadFile. Now I am receiving the following:

(000019)11/23/2015 10:59:53 AM - chrathan user (ip)> 257 "/" is current directory.
(000019)11/23/2015 10:59:53 AM - user (ip)> TYPE I

(000019)11/23/2015 10:59:53 AM - user (ip)> disconnected.

EDIT2: Basically the folder I try to have access is a network share disk. When I changed to a local folder in my pc everything works. My issue finally is how can I have access to a network share disk?

Solution

  • Your m_FtpHost variable is set to use http, it needs to be ftp://ip:port/.

    Thats why the first line of your log is showing: STOR /file.pdf HTTP/1.1
