У меня есть класс прослушивателя асинхронного сокета, подобный этому:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net;
using System.Net.Sockets;
using System.Threading;
using log4net;
using log4net.Config;
using log4net.Repository;
using log4net.Appender;
namespace GatewayWindowsService.Code
{
// State object for reading client data asynchronously
public class ListenerStateObject
{
// Client socket.
public Socket workSocket = null;
// Size of receive buffer.
public const int BufferSize = 1024;
// Receive buffer.
public byte[] buffer = new byte[BufferSize];
// Received data string.
public StringBuilder sb = new StringBuilder();
}
public class AsynchronousSocketListener
{
// The address for the remote device
private const string address = "172.25.17.119";
// The port number for the remote device.
private const int port = 11000;
//LOG4NET LOG
private ILog log;
// Thread signal.
public static ManualResetEvent allDone = new ManualResetEvent(false);
public AsynchronousSocketListener(ILog log)
{
this.log = log;
}
public void StartListening()
{
// Data buffer for incoming data.
byte[] bytes = new Byte[1024];
// Establish the local endpoint for the socket.
// The DNS name of the computer
// running the listener is "host.contoso.com".
IPHostEntry ipHostInfo = Dns.Resolve(address);
IPAddress ipAddress = ipHostInfo.AddressList[0];
IPEndPoint localEndPoint = new IPEndPoint(ipAddress, port);
// Create a TCP/IP socket.
Socket listener = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
// Bind the socket to the local endpoint and listen for incoming connections.
try
{
listener.Bind(localEndPoint);
listener.Listen(100);
//while (true)
//{
// Set the event to nonsignaled state.
allDone.Reset();
// Start an asynchronous socket to listen for connections.
log.Info("Waiting for a connection...");
listener.BeginAccept(new AsyncCallback(AcceptCallback), listener);
// Wait until a connection is made before continuing.
allDone.WaitOne();
//}
}
catch (Exception e)
{
log.Error(e.ToString());
}
}
public void AcceptCallback(IAsyncResult ar)
{
// Signal the main thread to continue.
allDone.Set();
// Get the socket that handles the client request.
Socket listener = (Socket)ar.AsyncState;
Socket handler = listener.EndAccept(ar);
// Create the state object.
ListenerStateObject state = new ListenerStateObject();
state.workSocket = handler;
handler.BeginReceive(state.buffer, 0, ListenerStateObject.BufferSize, 0, new AsyncCallback(ReadCallback), state);
}
public void ReadCallback(IAsyncResult ar)
{
String content = String.Empty;
// Retrieve the state object and the handler socket
// from the asynchronous state object.
ListenerStateObject state = (ListenerStateObject)ar.AsyncState;
Socket handler = state.workSocket;
// Read data from the client socket.
int bytesRead = handler.EndReceive(ar);
if (bytesRead > 0)
{
// There might be more data, so store the data received so far.
state.sb.Append(Encoding.ASCII.GetString(state.buffer, 0, bytesRead));
// Check for end-of-file tag. If it is not there, read
// more data.
content = state.sb.ToString();
if (content.IndexOf("<EOF>") > -1)
{
// All the data has been read from the
// client. Display it on the console.
log.Info("Read " + content.Length + " bytes from socket. \n Data : " + content);
// Echo the data back to the client.
Send(handler, content);
}
else
{
// Not all data received. Get more.
handler.BeginReceive(state.buffer, 0, ListenerStateObject.BufferSize, 0, new AsyncCallback(ReadCallback), state);
}
}
}
private void Send(Socket handler, String data)
{
// Convert the string data to byte data using ASCII encoding.
byte[] byteData = Encoding.ASCII.GetBytes(data);
// Begin sending the data to the remote device.
handler.BeginSend(byteData, 0, byteData.Length, 0, new AsyncCallback(SendCallback), handler);
}
private void SendCallback(IAsyncResult ar)
{
try
{
// Retrieve the socket from the state object.
Socket handler = (Socket)ar.AsyncState;
// Complete sending the data to the remote device.
int bytesSent = handler.EndSend(ar);
log.Info("Sent " + bytesSent + " bytes to client.");
handler.Shutdown(SocketShutdown.Both);
handler.Close();
}
catch (Exception e)
{
log.Error(e.ToString());
}
}
}
}
Теперь я использую этот класс в службе Windows и создаю его экземпляр следующим образом:
//EXECUTED WHEN THE WINDOWS SERVICE IS STARTED
protected override void OnStart(string[] args)
{
log.Info("Windos Service Initiated");
sListener = new AsynchronousSocketListener(log);
sListener.StartListening();
}
Когда я пытаюсь запустить эти сервисы из сервисов, полоса прогресса идет и уходит, и в конце я получаю эту ошибку:
Windows не удалось запустить службу Windows шлюза на локальном компьютере Ошибка1053: Служба не ответила на запрос запуска или управления своевременно
Как мне решить эту проблему, запустив службу Windows с прослушиванием сокета?
Спасибо
