Socket Server同时处理多个客户端请求

我想使用Socket Server同时处理多个客户端的请求。 我有10个客户端,可以同时向我的服务器发送请求。 我怎么能处理这个? 有可能吗?

使用以下代码,我一次只能处理一个请求,在请求完成后,服务器接受下一个请求。 由于第10个客户需要等到9个请求完成。

任何帮助将不胜感激

以下是我用于Server Socket的代码

Socket _serverSocket;
byte[] _buffer = new byte[255];

void SetupServer()
{
    try 
    {
        Console.WriteLine ("Setting up server...");

        IPEndPoint ipEndPoint = new IPEndPoint (IPAddress.Parse(_ip), _port);

        // create server socket to listen new client's connection
        _serverSocket = new Socket (AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

        _serverSocket.Bind (ipEndPoint);
        _serverSocket.Listen (100);

        _serverSocket.BeginAccept (new AsyncCallback (AcceptCallback), null);
    } 
    catch (System.Exception ex) 
    {
        Console.WriteLine ("Server failed :: {0}", ex.Message);
    }
}

void AcceptCallback(IAsyncResult ar)
{
    Socket clientSocket = _serverSocket.EndAccept(ar);

    _serverSocket.BeginAccept(new AsyncCallback(AcceptCallback), null);

    clientSocket.BeginReceive(_buffer, 0, _buffer.Length, SocketFlags.None, new AsyncCallback(RecieveCallback), clientSocket);
}

void RecieveCallback(IAsyncResult ar)
{
    Socket clientSocket = (Socket)ar.AsyncState;

    int received = clientSocket.EndReceive(ar);

    // check if client is disconnected?
    if (received == 0)
    {
        Console.WriteLine("client is disconnected...");

        return;
    }

    // do whatever you want with received data here...
    byte[] dataBuf = new byte[received];

    Array.Copy(_buffer, dataBuf, received);

    string text = Encoding.ASCII.GetString(dataBuf);

    Console.WriteLine("Received Data: {0}", text);

    // accept new request
    clientSocket.BeginReceive(_buffer, 0, _buffer.Length, SocketFlags.None, new AsyncCallback(RecieveCallback), clientSocket);
}

您应该熟悉“多线程服务器”的概念。您应该为连接到服务器的每个客户端启动一个线程。因此,您可以同时处理多个客户端。或者,如果要尝试较新的.NET功能,可以使用Tasks Parallel Library

但是网上有很多例子描述了如何实现这样的服务器。
