Read a UDP package

Hi,
I'm trying to use this code:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3. using System.Net;
4. using System.Net.Sockets;
5. using System.Threading;
6. using System.IO;
7. using System;
8. using System.Text;
9.  
10. public delegate void ActivityEventHandlerUDP( string msg );
11.  
12. public class ActivityListener : MonoBehaviour
13. {
14.     private System.Threading.Thread ActivityListenerThread;
15.     private bool run = true;
16.     public event ActivityEventHandlerUDP activityData;
17.  
18.     private int receivePortUDP = 9901; //4252;
19.     private UdpClient client;
20.     private IPEndPoint remoteIpEndPoint;
21.  
22.     public string myMessage="";
23.  
24.  
25.  
26.     void Start(){
27.         Debug.Log ("Start Activity remote listener");
28.         //Only start listener if you are the main display
29.         //if(XimDisplayNetworkSettings.getXimNetworkingMode() == XimDisplayNetworkSettings.XIMNetworkingmodes.SERVER){
30.         //UDP
31.         /*
32.  
33.  
34.         */
35.         //}
36.  
37.         client = new System.Net.Sockets.UdpClient( receivePortUDP );
38.  
39.         remoteIpEndPoint = new System.Net.IPEndPoint( System.Net.IPAddress.Any, receivePortUDP );
40.  
41.         ActivityListenerThread = new System.Threading.Thread(new System.Threading.ThreadStart( listenActivityUDPThread ) );    
42.         ActivityListenerThread.Name = "Activity UDP listen thread";
43.         ActivityListenerThread.Start();
44.  
45.     }
46.  
47.     void OnDestroy(){
48.         run = false;
49.         if (ActivityListenerThread != null) ActivityListenerThread.Abort();
50.         if( client != null ) client.Close();
51.     }
52.  
53.  
54.     private void listenActivityUDPThread(){
55.         while(run){
56.  
57.             try{
58.                 //Read the bottle
59.                 byte[] packet = client.Receive( ref remoteIpEndPoint );
60.                 // send message //
61.                 if( packet != null && packet.Length > 0 ){
62.                     string message = ExtractString( packet, 0, packet.Length );
63.                     Debug.Log (message);
64.                     myMessage = message;
65.                     if(activityData != null){
66.                         activityData(message);
67.                     }
68.                 }
69.                 Debug.Log(myMessage);
70.             }
71.             catch (Exception e)
72.             {
73.                 Debug.Log( e.ToString() );
74.             }
75.         }
76.     }
77.  
78.     private string ExtractString( byte[] packet, int start, int length )
79.     {
80.         StringBuilder sb = new StringBuilder();
81.         for (int i = 0; i < packet.Length; i++) {
82.             sb.Append ((char)packet [i]);
83.         }
84.         return sb.ToString();
85.     }
86.  
87.     void ReadData(UdpClient ci, String text){
88.         Console.WriteLine("Received text message: "+text);
89.     }
90. }

And it works kind of well, but I don't find the way to extract the info of the osc package I'm sending.
The message is:
/activity "0.6343149, 0.24177371, 0.124862194, 0.9113936, 0.12371367, 0.48712423, 0.42828846, 0.69702476, 0.92075056, 0.104008615, 0.34763572, 0.2345885, 0.059998512, 0.31695354, 0.6864477, 0.8406349, 0.82458776, 0.22075915, 0.36120734, 0.975904, ..."
But in Unity I only read "/activity" as a message, the rest of the numbers doesn't appear.
Thanks for the help
