The easiest method is to add the WinSCP NuGet package to your project. This automatically includes WinSCPnet.dll and the required WinSCP.exe .

using System; using WinSCP; class SftpDownload { public static int Main() { try { // 1. Setup Session Options SessionOptions sessionOptions = new SessionOptions { Protocol = Protocol.Sftp, HostName = "example.com", UserName = "user", Password = "mypassword", // Required for security to prevent man-in-the-middle attacks SshHostKeyFingerprint = "ssh-rsa 2048 xxxxxxxxxxx..." }; using (Session session = new Session()) { // 2. Open the Session session.Open(sessionOptions); // 3. Download Files TransferOptions transferOptions = new TransferOptions(); transferOptions.TransferMode = TransferMode.Binary; // Download all files from /home/user/ to d:\download\ TransferOperationResult transferResult = session.GetFiles("/home/user/*", @"d:\download\", false, transferOptions); // Check for errors during transfer transferResult.Check(); foreach (TransferEventArgs transfer in transferResult.Transfers) { Console.WriteLine($"Download of {transfer.FileName} succeeded"); } } return 0; } catch (Exception e) { Console.WriteLine($"Error: {e.Message}"); return 1; } } } Use code with caution. 3.
