Example Usage

private static class opcodes
{
    public static int HANDSHAKE = 100;
}
        
Packet pkt = new Packet(opcodes.HANDSHAKE, littleEndian: false);
pkt.writeInt(123456);
pkt.writeString("Emre Demircan");
  
int Number = pkt.readInt(); // 123456
string Name = pkt.readString(); // Emre Demircan

Send

Client client = new Client("127.0.0.1", 2000);

Packet sendData = new Packet(0xAABB);
sendData.writeInt(123456);
sendData.writeString("Emre Demircan");
sendData.Encrypt(); // automatically will be decrypted when received packet.

if (!sendData.Send(client.s)) // Client -> Server
    MessageBox.Show("Send Failed");

Recv

public int ClientHandler(Socket client)
{
    Packet pktReceiver = new Packet();
    while (client.Connected)
    {
        if (!pktReceiver.Recv(client))
            break;

        if (pktReceiver.GetOpcode() == 0xAABB)
        {
            int Number = pktReceiver.readInt(); //123456
            string Name = pktReceiver.readString(); // Emre Demircan
            
            Console.WriteLine("Opcode: "+ pktReceiver.GetOpcode());            
            Console.WriteLine("Number:" + Number);
            Console.WriteLine("Name:" + Name);            
        }
    }
    return 0;
}

Server server = new Server(2000, ClientHandler);

Output:

Opcode: 43707 (0xAABB)
Number: 123456
Name: Emre Demircan


sendData.Print();
