Rebex.Ftp 8.0.9797

Rebex FTP - The C# FTP/SSL library for .NET

Rebex FTP is an FTP and FTP/SSL (FTPS) client library for .NET developers. It provides remote file system access using the FTP protocol with optional TLS/SSL encryption. With Rebex FTP, it's simple to transfer files between your application and any FTP server, with support for both explicit and implicit TLS/SSL modes. For server-side, use Rebex.FileServer package.

20+ years of active development. Rebex FTP has been continuously developed and maintained since 2003, with regular updates and new features.

Key features

• File transfers - upload, download, rename, delete, directory transfers with wildcards, resume capability
• FTP/SSL (FTPS) modes - explicit and implicit TLS/SSL modes, data transfer encryption control
• Cryptographic algorithms including PQC - ML-KEM, ML-DSA, Ed25519, ChaCha20/Poly1305, AES/GCM, ECDH, ECDSA, RSA, and more
• Multiple authentication modes - password, X.509 client certificates
• Async/await API - Task-based asynchronous API support
• Bandwidth throttling - transfer speed limiting, progress monitoring
• Server-to-server transfers (FXP) - direct file transfers between FTP servers
• Protocol-agnostic API - shared IFtp interface for writing code that works with both FTP and SFTP
• ZLIB compression - compressed data transfers
• FIPS 140-3 compliant mode

Getting started

Connect, authenticate and download

using (var ftp = new Rebex.Net.Ftp())
{
    ftp.Connect("server.example.org");

    ftp.Login("username", "password");
    ftp.Download("/pub/example/readme.txt", @"C:\MyData");
}

Connect using explicit TLS/SSL

using (var ftp = new Rebex.Net.Ftp())
{
    // connect to a server using explicit TLS/SSL
    ftp.Connect("server.example.org", SslMode.Explicit);

    ftp.Login("username", "password");
    ftp.Download("/pub/example/readme.txt", @"C:\MyData");
}

List directory content

// navigate to desired directory
ftp.ChangeDirectory("/pub/example");

// get content of the current directory
var list = ftp.GetList();

// print info about retrieved items
foreach (var item in list)
{
    Console.WriteLine($"{item.Type} {item.Name}");
}

Upload files and directories

// upload a single file
ftp.PutFile(@"C:\MyData\report.txt", "/uploads/report.txt");

// upload all .txt files in a directory
ftp.Upload(@"C:\MyData\*.txt", "/uploads", TraversalMode.MatchFilesShallow);

Delete remote file or directory

// delete remote file
ftp.DeleteFile("/MyData/file.txt");

// delete whole remote directory
// (deletes "/MyData/Temp" directory itself as well)
ftp.Delete("/MyData/Temp", TraversalMode.Recursive);

Bandwidth throttling

// set download and upload speed limits
ftp.MaxDownloadSpeed = 128 * 1024;
ftp.MaxUploadSpeed = 64 * 1024;

Auto-resuming failed transfers

// auto-resume failed directory upload
ftp.Upload(@"C:\MyData\*", "/MyData", 0, 0, ActionOnExistingFiles.ResumeIfPossible);

Server-to-server transfer (FXP)

// connect to the source FTP server
var ftp1 = new Rebex.Net.Ftp();
ftp1.Connect(hostname1, port1);
ftp1.Login(username1, password1);

// connect to the destination FTP server
var ftp2 = new Rebex.Net.Ftp();
ftp2.Connect(hostname2, port2);
ftp2.Login(username2, password2);

// copy a single file to the destination server
ftp1.CopyToAnotherServer(ftp2, "/Incoming/file1.txt", "/MyData/file1.txt");
