See more: Server socket udp
Hello everybody!
I have a game server (WoW).
I want my players to download my custom patches to the game.
I've done a program that checks for update/downloading things.
I want my program to send a packet to my game server if player have all my patches. I dont need any response from the server, it will handle it, but its another story.
So I want to know, how to send a packet to a server.
Thank you!

Use the UDPClient class, here is the example straight from MSDN;

// This constructor arbitrarily assigns the local port number.
UdpClient udpClient = new UdpClient(11000);
         udpClient.Connect("", 11000);
         // Sends a message to the host to which you have connected.
         Byte[] sendBytes = Encoding.ASCII.GetBytes("Is anybody there?");
         udpClient.Send(sendBytes, sendBytes.Length);
         // Sends a message to a different host using optional hostname and port parameters.
         UdpClient udpClientB = new UdpClient();
         udpClientB.Send(sendBytes, sendBytes.Length, "AlternateHostMachineName", 11000);
         //IPEndPoint object will allow us to read datagrams sent from any source.
         IPEndPoint RemoteIpEndPoint = new IPEndPoint(IPAddress.Any, 0);
         // Blocks until a message returns on this socket from a remote host.
         Byte[] receiveBytes = udpClient.Receive(ref RemoteIpEndPoint); 
         string returnData = Encoding.ASCII.GetString(receiveBytes);
         // Uses the IPEndPoint object to determine which of these two hosts responded.
         Console.WriteLine("This is the message you received " +
         Console.WriteLine("This message was sent from " +
                                     RemoteIpEndPoint.Address.ToString() +
                                     " on their port number " +
       catch (Exception e ) {
