Using the TCP connection on KingServer

// create and start the async server
var server = new KingServer(port: 7171);
server.MessageReceivedHandler = OnMessageReceived;

//ASync execution
await server.StartAsync(); //You can pass a out var cancellationToken in parameter
//Sync execution
server.Start();

// implements the callback for MessageReceivedHandler
private void OnMessageReceived(IClient client, IKingBufferReader reader)
{
    Console.WriteLine($"Received data from client {client.Id}, data length {reader.Length()}");
}

// send a message to all clients
using(var writer = KingBufferWriter.Create())
{
    writer.Write("Test message!");
    server.SendMessageToAll(writer);
}

// stop the server when you don't need it anymore
server.Stop();

Using the TCP connection on KingClient

// create and connect the client
var client = new KingClient();
client.MessageReceivedHandler = OnMessageReceived;
client.Connect("127.0.0.1", 7171);

// implements the callback for MessageReceivedHandler
private void OnMessageReceived(IKingBufferReader reader)
{
    Console.WriteLine($"Received data from server, data length {reader.Length()}");
}

/// send a message to server
using(var writer = KingBufferWriter.Create()
{
    writer.Write("Test message!");
    client.SendMessage(writer);
}

// disconnect from the server when we are done
client.Disconnect();

Using the UDP connection on KingServer

// create and start the server
var server = new KingServer(listenerType: NetworkListenerType.UDP, port: 7171);
server.MessageReceivedHandler = OnMessageReceived;

//ASync execution
await server.StartAsync(); //You can pass a out var cancellationToken in parameter

Using the RUDP connection on KingServer

// create and start the server
var server = new KingServer(listenerType: NetworkListenerType.RUDP, port: 7171);

}

// send a message to all clients
using(var writer = KingBufferWriter.Create())
{
    writer.Write("Test message!");
    //You can use RudpMessageType.Reliable to send Reliable messages and RudpMessageType.Unreliable to send Unreliable messages
    server.SendMessageToAll(writer, RudpMessageType.Reliable);
}

// stop the server when you don't need it anymore
server.Stop();

    client.SendMessage(writer, RudpMessageType.Reliable);
}

// disconnect from the server when we are done
client.Disconnect();

Using the WebSocket connection on KingServer

// create and start the server
var server = new KingServer(listenerType: NetworkListenerType.WSText, port: 7171); // Or NetworkListenerType.WSBinary
server.MessageReceivedHandler = OnMessageReceived;

//ASync execution
await server.StartAsync(); //You can pass a out var cancellationToken in parameter
//Sync execution
server.Start();

// implements the callback for MessageReceivedHandler
private void OnMessageReceived(IClient client, IKingBufferReader reader)
{
    Console.WriteLine($"Received data from client {client.Id}, data length {reader.Length()}");
}

// send a message to all clients
using(var writer = KingBufferWriter.Create())
{
    writer.Write("Test message!");
    server.SendMessageToAll(writer);
}

// stop the server when you don't need it anymore

TCP Benchmarks

Connections Test
We also test only the raw KingNetwork library by spawing 1 server and 1000 clients, each client sending 100 bytes 14 times per second and the server echoing the same message back to each client. Test Computer: Acer F 15 with a 2,9 GHz Intel Core i7 7gen processor and 32 GB ram DDR4.
Test Results:

Clients	CPU Usage	Ram Usage	Bandwidth Client+Server	Result
64	0.5%	9 MB	0.3 MB/s	Passed
128	1%	10 MB	0.7 MB/s	Passed
500	18%	18 MB	2~3 MB/s	Passed
1000	32%	26 MB	5~6 MB/s	Passed
