C# FluentFTP

last modified February 28, 2023

In this article we show how to work with FTP in C# using FluentFTP.

FluentFTP is an FTP and FTPS client for .NET. It supports many FTP commands, file uploads and downloads, SSL/TLS connections, file hashing and checksums, file permissions or FTP proxies.

File Transfer Protocol (FTP) is a standard network protocol used for transfering of computer files between a client and server on a computer network. Clients and servers communicate with a set of FTP commands, such as DELE, RETR, or CWD.

$ dotnet add package FluentFTP

We add the package to the project.

C# FluentFTP make directory

In the first example, we create a remote directory.

using FluentFTP;

var host = "example.com";
var username = "user7";
var passwd = "s$cret";

var path = "/web/test/index.html";
var baseName = Path.GetFileName(path);

using var con = new FtpClient(host, username, passwd);
con.Connect();

var status = con.DownloadFile($"{baseName}", path, 
    FtpLocalExists.Overwrite, FtpVerify.Retry);

var msg = status switch {

    FtpStatus.Success => "file successfully downloaded",
    FtpStatus.Failed => "failed to download file",
    _ => "unknown"
};

Console.WriteLine(msg);
