AsyncNet

Asynchronous network library for .NET

Documentation

Wiki

Purpose

The primary purpose of this library is to provide easy to use interface for TCP and UDP networking in C#

Getting started

This repository contains multiple projects that fall into different category. See below.

AsyncNet.Tcp

Installation

NuGet

Features:

• Easy to use TCP server
• Easy to use TCP client
• SSL support
• Custom protocol deframing / defragmentation support

Basic Usage

TCP Server

var server = new AsyncNetTcpServer(7788);
server.ServerStarted += (s, e) => Console.WriteLine($"Server started on port: " +
    $"{e.ServerPort}");
server.ConnectionEstablished += (s, e) =>
{
    var peer = e.RemoteTcpPeer;
    Console.WriteLine($"New connection from [{peer.IPEndPoint}]");

    var hello = "Hello from server!";
    var bytes = System.Text.Encoding.UTF8.GetBytes(hello);
    peer.Post(bytes);
};
server.FrameArrived += (s, e) => Console.WriteLine($"Server received: " +
    $"{System.Text.Encoding.UTF8.GetString(e.FrameData)}");
await server.StartAsync(CancellationToken.None);

TCP Client

var client = new AsyncNetTcpClient("127.0.0.1", 7788);
client.ConnectionEstablished += (s, e) =>
{
    var peer = e.RemoteTcpPeer;
    Console.WriteLine($"Connected to [{peer.IPEndPoint}]");

    var hello = "Hello from client!";
    var bytes = System.Text.Encoding.UTF8.GetBytes(hello);
    peer.Post(bytes);
};
client.FrameArrived += (s, e) => Console.WriteLine($"Client received: " +
    $"{System.Text.Encoding.UTF8.GetString(e.FrameData)}");
await client.StartAsync(CancellationToken.None);

Awaitaible TCP Client

var client = new AsyncNetTcpClient("127.0.0.1", 7788);

using (var awaitaibleClient = new AwaitaibleAsyncNetTcpClient(client))
{
    try
    {
        var awaitaiblePeer = await awaitaibleClient.ConnectAsync();

        var hello = "Hello from client!";
        var bytes = System.Text.Encoding.UTF8.GetBytes(hello);

        await awaitaiblePeer.RemoteTcpPeer.SendAsync(bytes);
        var response = await awaitaiblePeer.ReadFrameAsync();

        Console.WriteLine($"Client received: " +
            $"{System.Text.Encoding.UTF8.GetString(response)}");
    }
    catch (Exception ex)
    {
        Console.WriteLine(ex);
        return;
    }
}

AsyncNet.Udp

Installation

NuGet

Features:

• Easy to use UDP server
• Easy to use UDP client

Basic Usage

UDP Server

var server = new AsyncNetUdpServer(7788);
server.ServerStarted += (s, e) => Console.WriteLine($"Server started on port: {e.ServerPort}");
server.UdpPacketArrived += (s, e) =>
{
    Console.WriteLine($"Server received: " +
        $"{System.Text.Encoding.UTF8.GetString(e.PacketData)} " +
        "from " +
        $"[{e.RemoteEndPoint}]");

    var response = "Response!";
    var bytes = System.Text.Encoding.UTF8.GetBytes(response);
    server.Post(bytes, e.RemoteEndPoint);
};
await server.StartAsync(CancellationToken.None);

UDP Client

var client = new AsyncNetUdpClient("127.0.0.1", 7788);
client.ClientReady += (s, e) =>
{
    var hello = "Hello!";
    var bytes = System.Text.Encoding.UTF8.GetBytes(hello);

    e.Client.Post(bytes);
};
client.UdpPacketArrived += (s, e) =>
{
    Console.WriteLine($"Client received: " +
        $"{System.Text.Encoding.UTF8.GetString(e.PacketData)} " +
        "from " +
        $"[{e.RemoteEndPoint}]");
};
await client.StartAsync(CancellationToken.None);
