using System;
using Renci.SshNet;

class Program
{
    static void Main()

        string host = "sftp.example.com";
        string username = "your_username";
        string password = "your_password";
        string remoteFilePath = "/path/to/remote/file.txt";
        string localFilePath = "C:\\path\\to\\local\\file.txt";

        using (var client = new SftpClient(host, username, password))
        {
            client.Connect();

            using (var fileStream = System.IO.File.OpenWrite(localFilePath))
            {
                client.DownloadFile(remoteFilePath, fileStream);
            }

            client.Disconnect();
        }
