我最近编写了一个套接字管理器，用于接收与我的游戏服务器的连接。每次客户端连接时，都会创建一个新的GameClient实例。问题是，目前正在创建3个GameClient实例，我不知道为什么。有人可以提供帮助，因为我只想要一个连接而且我真的不确定它为什么要创建3？
我的代码如下......
namespace Emulator.Core.Network.GameSockets
{
using System;
using System.Net;
using System.Net.Sockets;
using Base.Game.Habbo.Players.Players;
using NLog;
internal sealed class GameSocketManager : IDisposable
{
private static readonly ILogger Logger = LogManager.GetCurrentClassLogger();
private readonly Socket _gameSocket;
public GameSocketManager()
{
_gameSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
Start();
}
private void Start()
{
var gameSocketPort = Convert.ToInt32(Config.GetConfigValueByKey("game.socket.port"));
var gameSocketBacklog = Convert.ToInt32(Config.GetConfigValueByKey("game.socket.backlog"));
_gameSocket.Bind(new IPEndPoint(IPAddress.Any, gameSocketPort));
_gameSocket.Listen(gameSocketBacklog);
_gameSocket.BeginAccept(OnAcceptConnection, _gameSocket);
}
private void OnAcceptConnection(IAsyncResult asyncResult)
{
try
{
if (_gameSocket == null)
{
return;
}
var server = (Socket)asyncResult.AsyncState;
var client = server.EndAccept(asyncResult);
var uniqueId = Guid.NewGuid().ToString();
var newPlayer = new GameClient(client, uniqueId);
if (!GameManager.PlayerManager.TryAddPlayer(newPlayer))
{
Logger.Error("Failed to register new player on " + client.RemoteEndPoint);
}
}
catch (SocketException socketException)
{
Logger.Fatal("Failed to accept socket connection: " + socketException.Message);
Logger.Fatal(socketException);
}
finally
{
_gameSocket?.BeginAccept(OnAcceptConnection, _gameSocket);
}
}
public void Dispose()
{
Dispose(true);
}
private void Dispose(bool disposing)
{
if (!disposing)
{
return;
}

}
