Is there a dot42 equivalent to System.Net.Sockets.UdpClient?

Question

First off, I am new to Android and dot42. I have built a UDP Listener class, which is working fine in a Windows application. I am using the System.Net.Sockets.UdpClient class.

Now, I have tried to use my UDP Listener class in a dot42 project, but I get the error message

Type System.Net.Sockets.UdpClient not found.

I guess, this class is not available within dot42?

Is there a way I can use the same code below (or only a few modifications) for Android apps?

using System;
using System.Net;
using System.Net.Sockets;

namespace FSInterface
{
    public class UDPReceiver
    {
        private UdpClient _udpRx;
        private IPEndPoint ep;
        private int _port;

        public delegate void BytesReceive(byte[] buffer);
        public event BytesReceive OnBytesReceive;

        public UDPReceiver(int port)
        {
            _port = port;
            _udpRx = new UdpClient();
            _udpRx.Client.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.ReuseAddress, true);
            _udpRx.ExclusiveAddressUse = false;
            ep = new IPEndPoint(IPAddress.Any, _port);
            _udpRx.Client.Bind(ep);
            _udpRx.BeginReceive(new AsyncCallback(ReceiveCallback), null);
        }

        private void ReceiveCallback(IAsyncResult ar)
        {
            _udpRx.BeginReceive(new AsyncCallback(ReceiveCallback), null);

            byte[] buffer = _udpRx.EndReceive(ar, ref ep);

            if (OnBytesReceive != null)
            {
                OnBytesReceive(buffer);
            }
        }
    }
}

Dot42 is very promissing project, what is still missing is more complete set of BCL.

In this case you should use java classes. You can find many examples of client UDP code in java. If you want to share code between regular .net and dot42, you have to use interface to udp methods with separate implementations for regular .NET and Dot42.

Thank you, I will look into that. Let's hope for further development of dot42. Until then I guess I will have to learn some Java after all... – Flo Jan 13 '14 at 19:16

A little update. We released the .NET implementation under Apache License 2.0. You may now add missing types yourself. https://github.com/dot42/api.

So does that mean that the above code would work right away? Or do I have to supply the type definition in source code by myself? – Flo Mar 13 '14 at 08:19

No. Yes or someone else. Check the repo readme for instructions. – Frank Rem Mar 13 '14 at 08:22
