Question

这是我的代码，我将使用其ipv6地址连接到谷歌，但socket.connect（）方法最后是抛出超时异常，我需要一些解决方案，我应该在哪里更改我的代码，< / p>

        Uri google = new Uri("http://www.google.com");

        IPAddress[] ips = Dns.GetHostEntry(google.DnsSafeHost).AddressList;
        IPAddress ipAddress = ips[0];
        foreach (IPAddress ip in ips)
        {
            if (ip.AddressFamily == AddressFamily.InterNetworkV6)
                ipAddress = ip;
        }

        IPEndPoint endPoint = new IPEndPoint(ipAddress, 80);

        Socket socket = new Socket(endPoint.AddressFamily, SocketType.Stream, ProtocolType.Tcp);
        socket.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.KeepAlive, true);
        socket.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.ReceiveTimeout, 60 * 1000);
        socket.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.SendTimeout, 60 * 1000);
        socket.Connect(endPoint);

那么，您确定要连接到有效且在线且能够连接的IP地址吗？超时并不意味着IPv6存在问题。

对于ipv6地址，Socket.connect（）方法失败
