我有一个方法来创建一堆UDP套接字，用于向特定设备发送广播消息。这段代码在Windows上100%工作，但我的任务是创建一个MacOS版本。无论出于何种原因，我在将UdpClient Socket绑定到特定的IPEndPoint和端口时抛出SocketException（“Address already in use”）。我肯定有比我无知更愚蠢的事情，但我所有的研究都一无所获。任何帮助都是有帮助的。

        {
            if ((I.NetworkInterfaceType != NetworkInterfaceType.Loopback) && I.OperationalStatus == OperationalStatus.Up)
            {
                foreach (var Unicast in I.GetIPProperties().UnicastAddresses)
                {
                    if (Unicast?.Address?.AddressFamily == AddressFamily.InterNetwork)
                    {
