SynchronizeDownloadWithDeleteAsync(String,String,Object) Method

Transfer files that do not exist locally asynchronously OR Files that have a different byte count OR Files that have a modification date difference in seconds greater than 60. The hour difference between the local machine and the FTP server is taken into account when CalcHourDifference has been called. By default all files and sub directories are attempted to be synchronized. Local files and directories will be deleted if they do not exist in the corresponding FTP directory.

//FTP ftp = new FTP("place user name here", "place license key here");
 
// set the name of the FTP server( its URL )
ftp.HostAddress = "ftp.fsz.bme.hu"; // a hungarian university. change this to your ftp server
ftp.UserName = "anonymous"; // replace with your user name
ftp.Password = "user@mail.com"; // replace with your password
 
//Transfer files that do not exist locally OR Files that have a different byte count OR Files that have a modification date difference in seconds greater than 60 
ftp.SynchronizeDownloadWithDeleteAsync("C:\\Download", "TestDir");
 
while (ftp.IsBusy == true)
{
    System.Threading.Thread.Sleep(100);
}
 
System.Console.WriteLine("{0} files have been Transferred", ftp.FileCount);
