SFTP Server code examples, where?
I want to use your SFTP Server but your code examples seem very sparse to non-existent. I don't need Windows Forms or WPF examples, simple console examples will do. Among other things I would like to see examples of using asynchronous events for monitoring the server operations. Also documentation with suggestions for configuring the server would be nice.

Please have a look at this one:
using System;
using ComponentPro.Net.Servers;
using ComponentPro.Net;
using System.IO;
namespace Saml2Demo
{
class Program
{
static void Main()
{
ComponentPro.Licensing.Common.LicenseManager.SetLicenseKey("{TrialLicenseKey}");
using (var _server = new SftpSshServer())
{
// Add a private key
var rsaKey = GenerateOrGetServerKey();
_server.HostKeyStorage.Add(rsaKey);
string rootDir = AppDomain.CurrentDomain.BaseDirectory "root";
Directory.CreateDirectory(rootDir);
AddUser(_server, "test", "test", Path.GetFullPath(rootDir));
StartServer(_server, 2222, true);
while (true)
{
System.Threading.Thread.Sleep(1000);
}
}
}
static int _currentPort = -1;
///
/// Starts or stops the server.
///
/// true to start the server; otherwise false to stop the server.
static void StartServer(SftpSshServer server, int port, bool start)
{
if (start)
{
bool bind = false;
if (_currentPort == -1) // Start the server for the first time?
{
_currentPort = port;
bind = true;
}
else if (port != _currentPort) // If the server port has changed, we need to unbind the old port and bind to the new one.
{
// Unbind the old port.
server.ClosePort(_currentPort);
_currentPort = port;
bind = true;
}
if (bind)
{
// Enable SFTP subsystem
server.OpenPort(_currentPort, FileServerProtocol.Sftp);
// Enable shell-like SCP subsystem
server.OpenPort(_currentPort, FileServerProtocol.Scp);
}
// Start the server
server.Start();
Console.WriteLine("SFTP and SCP file server is running. Port: {0}.", port);
}
else

Console.WriteLine("Server has been stopped.");
}
}
static SecureShellPrivateKey GenerateOrGetServerKey()
{

const string keyFilePassword = "pass";
if (!File.Exists(keyFile))
{

}
else
{

}
return rsaKey;
}
static void AddUser(SftpSshServer server, string username, string password, string path)
{
// Create a new user with the new virtual root path
FileServerUser user = new FileServerUser(username, password, path);
bool addToList = true;
// If a user with the same username already exists, remove that one.
if (server.Users.Contains(username))
{
server.Users.Remove(username);
addToList = false;
}
// Add the new user.
server.Users.Add(user);
}
}
}
