Windows Phone 8.1 IRC

Question

I'm trying to make an IRC client for my Windows Phone 8.1 application, and I was lucky to find a really good tutorial. Unfortunately, the tutorial is for WP 7, and with WP 8.1 MS changed it to run-time applications, which means that SocketAsyncEvents not available to me (although MSDN says it supports Windows Phone 8.1).

 public void SendToServer(string message) { var asyncEvent = new SocketAsyncEventArgs { RemoteEndPoint = new DnsEndPoint(server, serverPort) }; var buffer = Encoding.UTF8.GetBytes(message + Environment.NewLine); asyncEvent.SetBuffer(buffer, 0, buffer.Length); connection.SendAsync(asyncEvent); } 

Digging around, I found that the sockets were moved to Windows.Networking.Sockets, but still none of them contained SocketAsyncEvents .

I pretty much cannot go further, does anyone have an idea on how to convert the specified function into something that will work with WP 8.1?

Like this!

After many studies, this is what I found:

First of all, we got a connection method.

 private readonly StreamSocket _clientSocket; private bool _connected; private DataReader _dataReader; public string Hostname { get; set; } public int Port { get; set; } public Credentials Credentials; public readonly string Channel; public async Task < bool > Connect() { if (_connected) return false; var hostname = new HostName(Hostname); await _clientSocket.ConnectAsync(hostname, Port.ToString()); _connected = true; _dataReader = new DataReader(_clientSocket.InputStream) { InputStreamOptions = InputStreamOptions.Partial }; ReadData(); return true; } 

To read the data that we receive through StreamSocket, we create the ReadData () method and make it recursive so that we continue to receive data:

 async private void ReadData() { if (!_connected || _clientSocket == null) return; uint s = await _dataReader.LoadAsync(2048); string data = _dataReader.ReadString(s); if (data.Contains("No ident response")) SendIdentity(); if (Regex.IsMatch(data, "PING :[0-9]+\\r\\n")) ReplyPong(data); ReadData(); } 

Now we have two new methods: SendIdentity(); and ReplyPong(string message); Usually the IRC server will ping you, here you should respond with an awning, for example:

 private void ReplyPong(string message) { var pingCode = Regex.Match(message, "[0-9]+"); SendRawMessage("PONG :" + pingCode); } 

And we also need to send our identity when the server is ready for it, for example:

 private void SendIdentity() { if (Credentials.Nickname == string.Empty) Credentials.Nickname = Credentials.Username; SendRawMessage("NICK " + Credentials.Nickname); SendRawMessage("USER " + Credentials.Username + " " + Credentials.Username + " " + Credentials.Username + " :" + Credentials.Username); if (Credentials.Password != String.Empty) SendRawMessage("PASS " + Credentials.Password); } public class Credentials { public string Nickname { get; set; } public string Username { get; set; } public string Password { get; set; } public Credentials(string username, string password = "", string nickname = "") { Username = username; Password = password; Nickname = nickname; } } 

Finally, we have our SendRawMessage(); method SendRawMessage(); that sends data to the server.

 async private void SendRawMessage(string message) { var writer = new DataWriter(_clientSocket.OutputStream); writer.WriteString(message + "\r\n"); await writer.StoreAsync(); await writer.FlushAsync(); writer.DetachStream(); if (!_closing) return; _clientSocket.DisposeSafe(); _connected = false; } 

I almost forgot the dispose function, which you can call when you want to close the stream :)

 public void Dispose() { SendRawMessage("QUIT :"); _closing = true; } 

This will send a final message indicating that we are leaving, and since now the close is now true, after that the thread will be deleted.
