I'm trying to create a windows service that needs to run in the background and listen for incoming traffic (a normal and regular TCP listener)
my code is:
private TcpListener server;
public void startServer()
{
// EventLog.WriteEntry(source, "connected on: " + ipAddress.ToString() + " port: " + Service1.Port.ToString());
server = new TcpListener(IPAddress.Parse("127.0.0.1"), Service1.Port);
server.Start();
while (true)
{
var client = server.AcceptTcpClient();
new Thread(work).Start(client);
}
public void work(object client)
{
string msg = null;
var clientLocal = (TcpClient)client;
using (NetworkStream ns = clientLocal.GetStream())
using (StreamReader sr = new StreamReader(ns))
{
byte[] msgFullArray = new UTF8Encoding(true).GetBytes(msg);
fs.Write(msgFullArray, 0, msg.Length);
}
now if you don't look at the work method at all as whenever i start my service it freezes whenever i try to start it at my :
var client = server.AcceptTcpClient();
meaning my service never gets to use the Thread or my Work method.. i can see from previous logging that it enters my while loop and then just times out the service
In your OnStart
Method you have to instantiate a server class.
protected override void OnStart(string[] args)
{
// Create the Server Object ans Start it.
server = new TCPServer();
server.StartServer();
}
that is responsible to handle the connections to the server by creating a new Thread
(so that it is a non-blocking process)
public void StartServer()
{
if (m_server!=null)
{
// Create a ArrayList for storing SocketListeners before
// starting the server.
m_socketListenersList = new ArrayList();
// Start the Server and start the thread to listen client
// requests.
m_server.Start();
m_serverThread = new Thread(new ThreadStart(ServerThreadStart));
m_serverThread.Start();
// Create a low priority thread that checks and deletes client
// SocktConnection objcts that are marked for deletion.
m_purgingThread = new Thread(new ThreadStart(PurgingThreadStart));
m_purgingThread.Priority=ThreadPriority.Lowest;
m_purgingThread.Start();
}
}
for each socket that it will be listening by a TCPListener
.
private void ServerThreadStart()
{
// Client Socket variable;
Socket clientSocket = null;
TCPSocketListener socketListener = null;
while(!m_stopServer)
{
try
{
// Wait for any client requests and if there is any
// request from any client accept it (Wait indefinitely).
clientSocket = m_server.AcceptSocket();
// Create a SocketListener object for the client.
socketListener = new TCPSocketListener(clientSocket);
// Add the socket listener to an array list in a thread
// safe fashon.
//Monitor.Enter(m_socketListenersList);
lock(m_socketListenersList)
{
m_socketListenersList.Add(socketListener);
}
//Monitor.Exit(m_socketListenersList);
// Start a communicating with the client in a different
// thread.
socketListener.StartSocketListener();
}
catch (SocketException se)
{
m_stopServer = true;
}
}
}
