Question

SOCKET  client  = accept(listen_sock, 0, 0);

timeval client_to;
client_to.tv_sec    = 1;
client_to.tv_usec   = 0;
setsockopt(client, SOL_SOCKET, SO_RCVTIMEO, (char*)&client_to, sizeof(client_to));
char    buffer[1024];
while ((ret = recv(client, buffer, 1024, 0)) != 0)
{
    cout    << "<in loop>" << endl;
    if (ret == -1 && WSAGetLastError() != WSAETIMEDOUT) break;
    if (ret > 0)    cout    << std::string(buffer, 0, ret) << endl;
}

closesocket(client);

上面的代码是用C ++编写的简单echo服务器的一部分。我面临的问题是......

如何设置超时值并检测超时时间已过期？
如何检测插座断开？

请让我在C＃中显示一些代码。感谢。

添加＆gt;＆gt;＆gt;＆gt;＆gt;＆gt;＆gt;＆gt;＆gt;＆gt;＆gt;＆gt;＆gt;＆gt;＆gt;＆gt;＆gt;＆gt;＆gt;＆gt;＆gt;＆gt;＆gt;＆gt;＆gt;＆gt;＆gt;＆gt;＆gt; ＆GT;＆GT;＆GT;＆GT;＆GT;＆GT;＆GT;＆GT;＆GT;

我的部分C＃代码遵循......

try
{
    // Read all
    spider.Client.ReceiveTimeout = 500; // spider is TcpClient type and blocking socket.
    int readCount = 0;
    SocketError socketError;
    while ((readCount = spider.Client.Receive(tempBuffer, 0, tempBuffer.Length, SocketFlags.None, out socketError)) > 0) // I  think time-out does not work, Receive() returns immediately.
    {
    recvBuffer.Append(tempBuffer, 0, readCount);
    }
}
catch (Exception e) // even though spider is disconnect, no exception occurred. how can I detect disconnection?
{
    Console.WriteLine("Exception: {0}", e.Message);

}

通过 XF.Server 查看。strong的 kodart 套接字库。下载库时，它附带一个echo服务器作为Xf.Server库的示例实现。这对你有用。

感谢。

我想将简单的C ++ echo服务器移植到C＃
