FTP Sync Download Tree w/ Must-Match Directory Constraints

See more FTP Examples

Demonstrates how synchronize a directory tree in the download direction, but only entering directories matching a set of wildcard filenames.

Note: This example requires Chilkat v9.5.0.76 or greater.

C#

bool success = false;

//  This example requires the Chilkat API to have been previously unlocked.
//  See Global Unlock Sample for sample code.

Chilkat.Ftp2 ftp = new Chilkat.Ftp2();

ftp.Hostname = "ftp.something.com";
ftp.Username = "my_login";
ftp.Password = "my_password";

//  Connect and login to the FTP server.
success = ftp.Connect();
if (success != true) {
    Debug.WriteLine(ftp.LastErrorText);
    return;
}

//  Set the current remote directory to the root of
//  the tree to be downloaded.
success = ftp.ChangeRemoteDir("/subDir1");
if (success != true) {
    Debug.WriteLine(ftp.LastErrorText);
    return;
}

//  Possible synchronization modes are:
//  mode=0: Download all files
//  mode=1: Download all files that do not exist on the local filesystem.
//  mode=2: Download newer or non-existant files.
//  mode=3: Download only newer files. If a file does not already exist on the local filesystem, it is not downloaded from the server..
//  mode=5: Download only missing files or files with size differences.
//  mode=6: Same as mode 5, but also download newer files.

//  Imagine our remote directory tree has these files and directories:

//  	accentedLatin1.txt
//  	accentedUtf8.txt
//  	alice.key
//  	anter_cert.pem
//  	chiliPepper.gif
//  	helloWorld.pdf
//  	abc/chiliPepper.gif
//  	abc/ghk/
//  	data/chiliPepper.gif
//  	data/xyz/dkimHtmlBody.txt
//  	data/xyz/dkimVerifyTest.eml
//  	data/xyz/emailForCreateDsn.eml
//  	text/frenchUtf8.txt
//  	text/helloWorld.txt
//  	text/PolishEmailBody.txt
//  	text/something/

//  Only enter remote directories named either "data" or matching "x*"
ftp.SyncMustMatchDir = "data; x*";
int mode = 0;
success = ftp.SyncLocalTree("c:/temp/subDir1",mode);
if (success != true) {
    Debug.WriteLine(ftp.LastErrorText);
    return;
}

success = ftp.Disconnect();

//  Show the files downloaded.
Chilkat.StringTable st = new Chilkat.StringTable();
ftp.GetSyncedFiles(st);

int numFiles = st.Count;
int i = 0;
string remoteFilename;
while (i < numFiles) {
    Debug.WriteLine(st.StringAt(i));
    i = i + 1;
}

//  Output showing the files downloaded:

//  accentedLatin1.txt
//  accentedUtf8.txt
//  alice.key
//  anter_cert.pem
//  chiliPepper.gif
//  helloWorld.pdf
//  data/chiliPepper.gif
//  data/xyz/dkimHtmlBody.txt
//  data/xyz/dkimVerifyTest.eml
//  data/xyz/emailForCreateDsn.eml
