示例1: SendUdpNetworkPacket
// Actually builds, sends, sets the received bytes and returns the whole packet
private EDNSPacket SendUdpNetworkPacket(string sDNSIP, string sIPToResolve, int nPort, byte bType, bool bEDNS, byte[] bMachine_ID)
{
// Create empty EDNS packet
EDNSPacket Packet = new EDNSPacket();
try
{
IPEndPoint Endpoint = new IPEndPoint(IPAddress.Parse(sDNSIP), nPort);
// Send the current machine_id host
if (bEDNS)
Packet.CreateEDNSPacketMachineID(sIPToResolve, bType, bMachine_ID);
else

// Create a udp client to send the packet
UdpClient udpGo = new UdpClient();
udpGo.Client.SendTimeout = 2000;
udpGo.Client.ReceiveTimeout = 2000;
udpGo.Send(Packet.GetPacket(), Packet.GetPacket().Length, Endpoint);
//IPEndPoint object will allow us to read datagrams sent from any source.
IPEndPoint RemoteIpEndPoint = new IPEndPoint(IPAddress.Any, 0);
