This is the way i do it:

  public static List<string> GetFtpDirectoryDetails(NetworkCredential cred, string strDir)
  {
     List<string> lst_strFiles = new List<string>();
     try
     {
        FtpWebRequest request = (FtpWebRequest)WebRequest.Create(strDir);
        request.Credentials = cred;
        request.Method = WebRequestMethods.Ftp.ListDirectoryDetails;
        FtpWebResponse response = (FtpWebResponse)request.GetResponse();
        //
        StreamReader file = new StreamReader(response.GetResponseStream());

        while (!file.EndOfStream)
        {
           lst_strFiles.Add(file.ReadLine());
        }

        file.Close();
        response.Close();
     }
     catch (Exception exc)
     {
        lst_strFiles.Add(exc.Message);
     }

     return lst_strFiles;
  }

This will gives the list of files and directories at a time..But i need the directory structure itself

Have you looked at (then) WebRequestMethods.Ftp.ListDirectory?

Or maybe you're looking for subdirectories.
Anyway, something here should work.

         try
         {
            FtpWebRequest request = (FtpWebRequest)WebRequest.Create(strDir);
            request.Credentials = cred;
            request.Method = WebRequestMethods.Ftp.ListDirectory;
            FtpWebResponse response = (FtpWebResponse)request.GetResponse();
            //
            StreamReader file = new StreamReader(response.GetResponseStream());

            while (!file.EndOfStream)
