I am creating an application which needs WebSocket Communication. All I need is a simple WebSocketServer with threading possibilities. I found that SuperWebSocket can satisfy my needs. But, my poor familiarity with C# makes trouble in understanding the code. Can anybody show me How to create a simple server Which should echo the message which is sent from the browser/WebPage. I will be very thankful to the person who shows some good direction||guide||code. I couldn't figure out the usage from their sample codes.

EDIT: This is the thing which I want to achieve. enter image description here

If anybody says an exact solution, I will adopt that one.

EDIT: "Robar" already gave the direct answer . This is jsut How I used it . 

this.NewSessionConnected += new SessionEventHandler<WebSocketSession>(this.WebSocketServer_NewSessionConnected);

this.NewDataReceived += new SessionEventHandler<WebSocketSession, byte[]>(this.WebSocketServer_NewDataReceived);

this.NewMessageReceived += new SessionEventHandler<WebSocketSession, string>(this.WebSocketServer_NewMessageReceived);

this.SessionClosed += new SessionEventHandler<WebSocketSession, SuperSocket.SocketBase.CloseReason>(this.WebSocketServer_SessionClosed);

SuperWebSocket

Tutorial for Echo example

Alchemy

If you are open to other C# WebSocket server you could use Alchemy. The server implementation is quite straight forward:

static void Main(string[] args) {
  var aServer = new WSServer(8100, IPAddress.Any) {
      DefaultOnReceive = new OnEventDelegate(OnReceive),
      DefaultOnSend = new OnEventDelegate(OnSend),
      DefaultOnConnect = new OnEventDelegate(OnConnect),
      DefaultOnConnected = new OnEventDelegate(OnConnected),
      DefaultOnDisconnect = new OnEventDelegate(OnDisconnect),
      TimeOut = new TimeSpan(0, 5, 0)
  };

  aServer.Start();
}

static void OnConnected(UserContext aContext) {
  Console.WriteLine("Client Connection From : " + aContext.ClientAddress.ToString());
  // TODO: send data back
}

As mentioned on their website, they have a simple chat example.

  • Alchemy is really cool! unfortunally it lack some features right now. SuperWebSockets is probably a better option for now. – Rushino Oct 16 '12 at 22:15
  • @Rushino: that's right. SuperWebSockets is currently the perfect solution for the projects in our company. – Robar Oct 17 '12 at 09:10

    That nice to hear ! i just started using it and i think its really wonderful how it work and it work very well so far. So if you using it in your company that prove my point. – Rushino Oct 17 '12 at 14:19
  • This project doesn't seem to be supported any more. There are several major issues and pull requests open for a year+. – Bryan Anderson Jul 25 '14 at 19:57
  • @BryanAnderson yeah thats right, Alchemy seems to be unsupported. As of today I would recommend SignalR for WebSocket communication. – Robar Jul 28 '14 at 10:04

class Program
{
    static void Main(string[] args)
    {
        var listener = new TcpListener(IPAddress.Loopback, 8181);
        listener.Start();
        using (var client = listener.AcceptTcpClient())
        using (var stream = client.GetStream())
        using (var reader = new StreamReader(stream))
        using (var writer = new StreamWriter(stream))
        {
            writer.WriteLine("HTTP/1.1 101 Web Socket Protocol Handshake");
            writer.WriteLine("Upgrade: WebSocket");
            writer.WriteLine("Connection: Upgrade");
            writer.WriteLine("WebSocket-Origin: http://localhost:8080");
            writer.WriteLine("WebSocket-Location: ws://localhost:8181/websession");
            writer.WriteLine("");
        }
        listener.Stop();
    }
