c#网络唤醒局域网内计算机（用mac地址）

方法一：

 public void WakeUp(string macString)
    {
        try
        {
            if (macString.Split('-').Length == 6)
            {
                string macStr = macString.Replace('-', ' '); ;

                byte[] macByteArray = HexStringSToByteArray(macStr);

                UdpClient client = new UdpClient();
                client.Connect(IPAddress.Broadcast, 1234);//IPAddress.Broadcast：默认广播地址"255.255.255.255"
                //client.Connect("127.0.0.1", 1234);

                //print(IPAddress.Broadcast);

                byte[] packet = new byte[17 * 6];
                for (int i = 0; i
