TcpServerOpenAsync(Boolean, Int32, NotifyDataChangedEventHandler) Method

Opens a TCP server. Creates a server and starts accepting connections, calling 'dataChangedHandler' with data from each connection as it arrives. This method returns after the server has been established, leaving the accepting and servicing of connections to a background thread.

Example
C#
Copy
// Start a new server, calling DataReceived for every packet received.
public async Task StartServerAsync(int port) {
    await TcpServer.OpenAsync(sync: false, port, DataReceived);
}

// Called when data is received.
void DataReceived(ProtocolSocket socket, object service, NotifyDataChangedEventArgs e) {
    var    io      = (IPacketIOService)service;    // TcpServer uses IPacketIOService.
    var    args    = (PacketChangedEventArgs)e;    // IPacketIOService posts PacketChangedEventArgs when it raises a DataChanged event.
    var    message = args.GetData();               // Read from the packet.
    string str     = BinaryTextEncoding.FixedLengthASCII.GetString(message);

    Logger.Log("Message received: " + message);

    // Send back a reply.
    var reply = BinaryTextEncoding.NullTerminatedASCII.GetBytes("hello");
    io.Write(reply);
