PurpleSofa - C# .NET async tcp server & client

  • Callback for 'OnOpen'(accepted or connected), 'OnMessage'(received), 'OnClose'(received none).
  • Can store user value in session.
  • Check timeout at regular intervals by last receive time. It's useful to detect 'half close'.
  • 'OnClose' execution is taken via queue in order to avoid simultaneously many 'close'.

how to use


public class Callback : PsCallback
    private const string Key = "inc";
    public override void OnOpen(PsSession session)
        Console.WriteLine($"OnOpen {session}");
        session.SetValue(Key, 0);

        int inc = session.GetValue<int>(Key);
        session.Send($"inc: {inc}");

    public override void OnMessage(PsSession session, byte[] message)
        Console.WriteLine($"OnMessage {session} {Encoding.UTF8.GetString(message)}");
        int inc = session.GetValue<int>(Key);
        session.SetValue(Key, inc);
        session.Send($"inc: {inc}");
        if (inc > 3) session.Close();

    public override void OnClose(PsSession session, PsCloseReason closeReason)
        int inc = session.GetValue<int>(Key);
        Console.WriteLine($"OnClose {session} {closeReason}, inc:{inc}");
