WCFServices

Hi,

I am working on the webservices for the first time where i have to FTP the Files to a specific location. All the files are generated by another method in a single location x.The first 3 characters of the file is how we identify the file belonging to which client. Every client will have 2 files to be FTPied.

From this x location we have to get these files and also get the client specific details from the database like clientname,landingzone,ftpusername etc.,

Below is what i wrote. first i am getting all the clients from GetClientInformation method in a webservice then wrote a for loop in order to access the properties of the service.
then i am checking for the files present in the x location.

Here i have to wait for 10 hours and check every 10 mins if my required file is prsent or not.f the 2 files for the specific client are present then we will ftp the files.

Could some one please let me know what should be done next.

        public bool Transmit()
        {
            try
            {
                strClientEncounterInfo = generateFile.GetClientInformation();
                foreach (var client in strClientEncounterInfo)
                {
                    strClientID=client.ClientEncounterId.ToString().Substring(0,3);
                    if (IsReportRequested == true)
                    {
                        var files = Directory.GetFiles(ConfigurationManager.AppSettings["ECG_LOCATION"], strClientID).Where(item => item.StartsWith(strClientID));
                        if (files.Count() == 2)
                        {
//FTP the files

                        }
                        else
                        {
isFilePresent(ConfigurationManager.AppSettings["ECG_LOCATION"], filename);
                        }

                    }
                }
            }
        }
        public bool isFilePresent(string path, string filename)
        {
            try
            {
                watcher = new FileSystemWatcher();
                watcher.Path = path;
                watcher.Filter = filename + "*.*";
                watcher.NotifyFilter = NotifyFilters.LastAccess |NotifyFilters.LastWrite |NotifyFilters.FileName |NotifyFilters.Size;
                watcher.Changed += new FileSystemEventHandler(OnChanged);
                watcher.Created += new FileSystemEventHandler(OnChanged);
                watcher.Deleted += new FileSystemEventHandler(OnChanged);
                //watcher.Renamed += new RenamedEventHandler(OnRenamed);
                watcher.EnableRaisingEvents = true;    
            }
            catch (Exception)
            {
                
                throw;
            }
            return true;
        }
        private static void OnChanged(object sender, FileSystemEventArgs e)
        {
            
        }
