A simple TCP server and client library

Example Usage

Server

using SlimTcpServer;

class Program
{
    static void Main(string[] args)
    {
        try
        {
            Console.WriteLine("SlimTcpServer - Server");

            var sever = new SlimServer();

            sever.ServerStarted += server => Console.WriteLine($"Server started on port: {server.ServerPort}");
            sever.ServerStopped += server => Console.WriteLine($"Server stopped");
            sever.ClientConnected += client => Server_ClientConnected(client);
            sever.ClientDisconnected += client => Console.WriteLine($"Client disconnected: {client.Guid}");

            sever.StartAsync().Wait();

            Console.ReadLine();
            sever.StopAsync().Wait();
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
        }
    }

    static void Server_ClientConnected(SlimClient client)
    {
        Console.WriteLine($"Client connected: {client.Guid}");
        _ = ClientRunLoop(client);
    }

    static async Task ClientRunLoop(SlimClient client)
    {
        await client.WriteAsync($"Hello, your Guid: {client.Guid}");
        while (client.IsConnected)
        {
            var message = await client.ReadAsync();
            Console.WriteLine($@"Client: {client.Guid}, data received : ""{message}""");
            if (message == "close")
            {
                Console.WriteLine($"Client close request");
                await client.DisconnectAsync();
            }
            else if (message == "play")
            {
                await client.WriteAsync("Lets play");
            }
        }
    }
}

Client

using SlimTcpServer;

class Program
{
    static void Main(string[] args)
    {
        Console.WriteLine("SlimTcpServer - Client");

        var client = new SlimClient();

        client.Disconnected += client => Console.WriteLine("Client disconnected");
        client.Connected += client => Console.WriteLine("Client connected");

        try
        {
            client.ConnectAsync("127.0.0.1").Wait();
            ClientRunLoop(client).Wait();
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
        }
    }

    static async Task ClientRunLoop(SlimClient client)
    {
        var serverMessage = await client.ReadAsync();
        Console.WriteLine(serverMessage);
        while (client.IsConnected)
        {
            var sendMsg = Console.ReadLine();
            sendMsg = sendMsg.Replace('`', '\0');
            if (sendMsg == "")
            {
                await client.DisconnectAsync();
                return;
            }
            await client.WriteAsync(sendMsg);
            if (sendMsg == "play")
            {
                var message = await client.ReadAsync();
                Console.WriteLine(message);
            }
        }
    }
}
