(C#) FTP Sync Upload Tree w/ Must-Match Filename Constraints

Demonstrates how synchronize a directory tree in the upload direction, but only upload files matching a set of wildcard filenames.

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

Chilkat .NET Downloads Chilkat .NET Framework Chilkat for .NET Core

// 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.
bool success = ftp.Connect();
if (success != true) {
    Debug.WriteLine(ftp.LastErrorText);
    return;
}

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

// Possible synchronization modes are:
// mode=0: Upload all files
// mode=1: Upload all files that do not exist on the FTP server.
// mode=2: Upload newer or non-existant files.
// mode=3: Upload only newer files. If a file does not already exist on the FTP server, it is not uploaded.
// mode=4: transfer missing files or files with size differences.
// mode=5: same as mode 4, but also newer files. 

// This example will upload all files, but only those files having filenames
// that match *.gif and *.eml

// Imagine our local 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/

ftp.SyncMustMatch = "*.eml; *.gif";
int mode = 0;
success = ftp.SyncRemoteTree("c:/temp/subDir1",mode);
if (success != true) {
    Debug.WriteLine(ftp.LastErrorText);
    return;
}

success = ftp.Disconnect();

// Show the files uploaded.
Debug.WriteLine(ftp.SyncedFiles);

// Output showing the files uploaded:

// chiliPepper.gif
// abc/chiliPepper.gif
// data/chiliPepper.gif
// data/xyz/dkimVerifyTest.eml
// data/xyz/emailForCreateDsn.eml
