CF 3.5 C中的套接字連接＃

Question

我正嘗試在手持設備和PC之間建立通信。

我有以下的代碼，對客戶：

public void connect(string IPAddress, int port) 
    { 
       // Connect to a remote device. 
     try 
     { 
      IPAddress ipAddress = new IPAddress(new byte[] { 192, 168, 1, 10 }); 
      IPEndPoint remoteEP = new IPEndPoint(ipAddress, port); 
      // Create a TCP/IP socket. 
      client = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); 
      // Connect to the remote endpoint. 
      client.BeginConnect(remoteEP, new AsyncCallback(ConnectCallback), client); 
      if (connectDone.WaitOne()){ 
       //do something.. 
      } 
      else{ 
       MessageBox.Show("TIMEOUT on WaitOne"); 
      } 
     } 
     catch(Exception e){ 
       MessageBox.Show(e.Message); 
     } 
     } 

我的問題是，當我在他們溝通罰款的PC上運行他們兩個，但在SmartDevice項目相同的代碼沒有按」 t連接在PC上運行的服務器，它給我這個錯誤：

System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or stablished connection failed 
because connected host has failed to respond 

我在想什麼？

注：IP地址是硬編碼的碼

編輯內：這裏是我拿from a MSDN example另一個代碼。這也行不通，它說它不可能讀取。在這種情況下，服務器的代碼是一樣的例子，客戶端代碼有修改：

private void button1_Click(object sender, EventArgs e) 
{ 
    // In this code example, use a hard-coded 
    // IP address and message. 
    string serverIP = "192.168.1.10";//HERE IS THE DIFERENCE 
    string message = "Hello"; 
    Connect(serverIP, message); 
}

在此先感謝您的幫助！

對於我的「移動設備」的客戶，我用這個數據發送到「PC」主持人：

private void Send(string value) { 
    byte[] data = Encoding.ASCII.GetBytes(value); 
    try { 
    using (TcpClient client = new TcpClient(txtIPAddress.Text, 8000)) { 
     NetworkStream stream = client.GetStream(); 
     stream.Write(data, 0, data.Length); 
    } 
    } catch (Exception err) { 
    // Log the error 
    } 
} 

對於主機，你最好使用一個線程或BackgroundWorker在那裏你可以讓一個TcpListener對象好整以暇：

private void Worker_TcpListener(object sender, DoWorkEventArgs e) { 
    BackgroundWorker worker = (BackgroundWorker)sender; 
    do { 
    string eMsg = null; 
    int port = 8000; 
    try { 
     _listener = new TcpListener(IPAddress.Any, port); 
     _listener.Start(); 
     TcpClient client = _listener.AcceptTcpClient(); // waits until data is avaiable 
     int MAX = client.ReceiveBufferSize; 
     NetworkStream stream = client.GetStream(); 
     Byte[] buffer = new Byte[MAX]; 
     int len = stream.Read(buffer, 0, MAX); 
     if (0 < len) { 
     string data = Encoding.UTF8.GetString(buffer); 
     worker.ReportProgress(len, data.Substring(0, len)); 
     } 
     stream.Close(); 
     client.Close(); 
    } catch (Exception err) { 
     // Log your error 
    } 
    if (!String.IsNullOrEmpty(eMsg)) { 
     worker.ReportProgress(0, eMsg); 
    } 
    } while (!worker.CancellationPending); 
}
