将C＃代码转换为Android

Question

I'm new to android. I've implemented kind of a hole punching in C# and I'm trying to implement the same logic in android.

Some of the classes from .NET solution that I Implemented new classes in android such as TimeSpan, though there are some classes that I need to implement and I got stacked.

1. Trying to get class in android that behave as CancellationTokenSource in .NET
2. There is some logic that works great in C# but I don't know how to implement it in android.

CODE:

    private static Boolean rec_and_wait(TimeSpan interval)
    {
        Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
        try
        {
            CancellationTokenSource cancellationTokenSource = new CancellationTokenSource();                
            byte[] data = new byte[1024];
            IAsyncResult ar = socket.BeginReceive(data, 0, data.Length, SocketFlags.None, null, null);
            int res = WaitHandle.WaitAny(new WaitHandle[] { ar.AsyncWaitHandle, _cancellationTokenSource.Token.WaitHandle }, interval.Add(TimeSpan.FromSeconds(10))); // allow extra 10 seconds for network delay
            switch (res)
            {
                case 0: // response
                    return true;
                case WaitHandle.WaitTimeout: // time out
                case 1: //cancelled
                default: // should not happen
                    return false;
            }
        }
        catch
        {
            return false;
        }
        finally
        {
            if (socket != null)
            {
                socket.Close();
                socket.Dispose();
                socket = null;
            }
        }
    }

Thanks

You could check out Xamarin . You can create Android, iOS, Mac and Windows apps with C# and Xamarin Studio compiles it for you to native applications.

Use a language converter tool. You can find some nice ones listed HERE

It wont give you a 100% result every time, but will take you close to the final result where with a few minor changes here and there you'll get what you want.
