client does not receive messages

i send a message from my tcp server to my unity client but the unity client never receives the server
i created some buttons to connect / disconnect / send a message to my server (which works fine!) but the receiving part never happens!

what do i have to do? i cant find the mistake

Code (CSharp):

1.  
2.  
3. public class alltogether : MonoBehaviour
4. {
5.  
6.     public TcpClient m_client = new TcpClient();
7.     public InputField myInputfield;
8.     byte[] data;
9.     byte[] rData;
10.  
11.  
12.     public void Connect()
13.     {
14.         m_client.Connect("127.0.0.1", 30005);
15.  
16.         if (m_client.Connected)
17.         {
18.             NetworkStream stream = m_client.GetStream();
19.  
20.             if (stream.CanRead)
21.             {
22.                 rData = new byte[1024];
23.                 stream.BeginRead(rData, 0, rData.Length, ReadCallback, rData);
24.             }
25.  
26.         }
27.     }
28.     private void ReadCallback (IAsyncResult result)
29.     {
30.         int read;
31.         NetworkStream stream = m_client.GetStream();
32.         try
33.         {
34.            
35.             read = stream.EndRead(result);
36.         }
37.         catch
38.         {
39.             Debug.Log("Error");
40.             return;
41.         }
42.         if (read == 0)
43.         {
44.             Debug.Log("Closed");
45.             return;
46.         }
47.         byte[] rData = result.AsyncState as byte[];
48.         stream.BeginRead(rData, 0, rData.Length, ReadCallback, rData);
49.         string responseBulk = Encoding.UTF8.GetString(rData);
50.         SendStringToParser(responseBulk);
51.     }
52.     void SendStringToParser(string responseBulk)
53.     {

58.     public void Disconnect()
59.     {
60.         if (m_client.Connected)
61.         {
62.             m_client.Close();
63.         }
64.     }
65.  
66.     public void SendMsgToPlant()
67.     {
68.         data = System.Text.Encoding.ASCII.GetBytes(myInputfield.text);
69.         NetworkStream m_stream = m_client.GetStream();
70.         m_stream.Write(data, 0, data.Length);
71.     }
72. }
