TCP

styleMaster

Ok this is my code for TCP socket that should run on Hololens. The problem in my code is that the last message I can see is Debug.Log("Connect"); and on the server I see no connection. Someone can tell me why?

public class UWPTcpClient : MonoBehaviour
{

public delegate void OnReadFinished(string result);
public event OnReadFinished ReadFinishedEvent;

public delegate void OnConnectFinished();
public event OnConnectFinished ConnectFinishedEvent;

private StreamSocket socket;
public bool isConnected = false;

public void Connect(string host, int port) {
     Debug.Log("Connect");
    var task = Task.Run(async () => { await ConnectAsync(host, port); });
}

private async Task ConnectAsync(string host, int port)
{
    Debug.Log("ConnectAsynch");
    socket = new StreamSocket();
    HostName hostName = new HostName(host);

    // Set NoDelay to false so that the Nagle algorithm is not disabled
    socket.Control.NoDelay = false;

    try
    {
        await socket.ConnectAsync(hostName, port.ToString());
        isConnected = true;
Debug.Log("Connected.");
    }
    catch (Exception exception)
    {
        switch (SocketError.GetStatus(exception.HResult))
        {
            case SocketErrorStatus.HostNotFound:
                Debug.Log("Host not found");
                throw;
            default:
                Debug.Log("exception on socket connection: " + exception.Message);
                throw;
        }
    }

    ConnectFinishedEvent();
}

public void Read() {

Debug.Log("Read()");
Task.Run(async () => { await ReadAsync(); });
}

private async Task ReadAsync()
{
    if (! isConnected)
    {
        return;
    }

    DataReader reader;
    StringBuilder strBuilder;

    using (reader = new DataReader(socket.InputStream))
    {
        strBuilder = new StringBuilder();
        reader.InputStreamOptions = InputStreamOptions.Partial;
        reader.UnicodeEncoding = Windows.Storage.Streams.UnicodeEncoding.Utf8;
        reader.ByteOrder = ByteOrder.LittleEndian;

        var count = await reader.LoadAsync(1024);
        if (count > 0)
        {
            strBuilder.Append(reader.ReadString(count));
            reader.DetachStream(); 
            ReadFinishedEvent(strBuilder.ToString());
        } else
        {
            ReadFinishedEvent("");
        }
    }
}

public void Close()
{
    socket.Dispose();
}

}

endif
