Question

我有一个用C＃.NET编写的服务器应用程序，并在Windows XP SP3上运行。

我正在使用异步套接字编程来处理大约500个客户端。

但我遇到了超过15个客户端连接的问题。

我的应用程序在15个客户端之后再连接1个客户端时关闭;我不是了解问题是出在我的操作系统上还是Windows XP中的tcp连接限制问题。

请帮助解决此问题，请提出任何解决方案。

这是我的一段代码。

public const int MAX_CLIENTS = 200;
public AsyncCallback pfnWorkerCallBack;

private Socket[] m_workerSocket = new Socket[MAX_CLIENTS];

// class for worker socket & callback method & data buffer
private SocketPacket[] m_workerSocketPkt = new SocketPacket[MAX_CLIENTS];

// page Load

m_mainSocket = new Socket(AddressFamily.InterNetwork,
                          SocketType.Stream,
                          ProtocolType.Tcp);
IPEndPoint ipLocal = new IPEndPoint(IPAddress.Any, 4321);
// Bind to local IP Address...
m_mainSocket.Bind(ipLocal);
// Start listening...
m_mainSocket.Listen(MAX_CLIENTS);

m_mainSocket.BeginAccept(new AsyncCallback(OnClientConnect), null);

// called when client is connected

public void OnClientConnect(IAsyncResult asyn)
{
    try
    {
        m_clientCount = setclient();

        SocketPacket abc = new SocketPacket();

        m_workerSocketPkt[m_clientCount] = abc; //assigning with SocketPacket class
        m_workerSocketPkt[m_clientCount].m_currentSocket =
                m_mainSocket.EndAccept(asyn);   //transferring connection to other thread
        m_workerSocketPkt[m_clientCount].m_clientCount = m_clientCount;

        m_workerSocketPkt[m_clientCount].templist = abcde; //assigning Amj (list) class
        m_workerSocket[m_clientCount] = m_workerSocketPkt[m_clientCount].m_currentSocket;

        pfnWorkerCallBack = new AsyncCallback(m_workerSocketPkt[m_clientCount].OnDataReceived); //defining AsynCallBack function for the accepted socket

        m_workerSocketPkt[m_clientCount].oldpfnWorkerCallBack = pfnWorkerCallBack;

        m_workerSocketPkt[m_clientCount].data_rec = false;
        m_workerSocketPkt[m_clientCount].data_sent = false;

        m_workerSocketPkt[m_clientCount].m_currentSocket.BeginReceive(
            m_workerSocketPkt[m_clientCount].dataBuffer,        //assigning data buffer for receiving for the socket
            0,                                                  //assigning data buffer offset for receiving for the socket
            m_workerSocketPkt[m_clientCount].dataBuffer.Length, //assigning maximum data length for receiving for the socket
            SocketFlags.None,                                   //socket flags
            pfnWorkerCallBack,                                  //AysnCallBack delegate
            m_workerSocketPkt[m_clientCount].m_currentSocket    //state
        );

        m_mainSocket.BeginAccept(new AsyncCallback(OnClientConnect), null); //start invitation for other new sockets
    }

最大客户端值在这里也是200个工作套接字，因此它应该处理200个客户端但我认为它在从超过15个客户端接收数据时产生了问题，因为连接的每个客户端都是连续连接的并且将数据发送到服务器

Answer 1

将m_workerSocketPkt数组（或m_workerSocket）增加到15以上或将其转换为List<>。（我猜是因为你没有表明它的声明）

Answer 2

即使是最基本的Windows XP系统也应该能够处理1000个连接。 TCP允许每个客户端机器数千个连接。（我不建议每台服务器超过100K）

如果您的程序失败，则可能是您的代码中的错误。有可能产生你忽略的错误吗？你的程序有什么错误？

服务器应用程序超过15个客户端处理问题的多个客户端
