c#TCP套接字服务器未响应客户端

我有一个使用Mono在Ubuntu 12.04下运行的C#服务器,代码如下:

while (true)
{
    Console.WriteLine("Socket ready...");
    using (Socket handlerSocket = listenerSocket.Accept())
    {
        Console.WriteLine("New request...");
        BackgroundWorker newBackgroundWorker = new BackgroundWorker();
        byte[] buffer = new byte[1024];
        Console.WriteLine("Buffer allocated...");
        handlerSocket.Receive(buffer);
        //newBackgroundWorker.DoWork += (s, o) =>
        //{
        using (Socket Sender = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp))
        {
            Console.WriteLine("Buffer received...");
            string request = Encoding.Unicode.GetString(buffer);
            Console.WriteLine("New request from : {0} /t Request : {1}", ((IPEndPoint)handlerSocket.RemoteEndPoint).Address.ToString(), request);
            if (request.Contains("$GetBattleList"))
            {
               //Chain of if's and else's continues
               //The following else if is the only case being tested
            else if (request.Contains("$GetZeroBasedProfile"))
            {
                Console.WriteLine("Sending profile...");
                Sender.Connect(handlerSocket.RemoteEndPoint); //Fails here due to not being able to reach the client application, throws a timeout exception
                Sender.SendFile(_profileLocation);
            }
            else Console.WriteLine("Invalid request. Ignoring...");
        }
    }
}

服务器能够接收客户端请求,但由于每次都无法连接,因此无法响应。我是在代码中遗漏了什么,还是这里有其他东西在起作用?

c#TCP套接字服务器未响应客户端

您所声明的附加Socket Sender是不必要的。从listenerSocket.Accept()收到的handlerSocket已经是可以用于与客户端通信的套接字。

当您接受使用服务器套接字的连接时,您得到的是连接到客户端的套接字。你不必创建一个新的套接字来连接(事实上,你不能)。因此,与其创建和使用Sender,不如使用handlerSocket:

handlerSocket.SendFile(_profileLocation);
