套接字操作尝试一个无法连接的主机windows CE的

我通过无线向PC发送从智能设备windows CE的文件，该文件是由TCP发送，它工作正常，当我被部署通过主动申请测试它从我的笔记本电脑同步。不过，当设备内安装的应用程序并没有发送的文件，它告诉我的例外：一个套接字操作尝试一个无法连接的主机的代码如下套接字操作尝试一个无法连接的主机windows CE的

private void button1_Click(object sender, EventArgs e) 
{ 
    string IPAddress = "10.1.1.102"; 
    string filPath = "\\student.XML"; 
    int PortNumber = 5656; 

    SendTCP(filPath, IPAddress, PortNumber);    
} 

public void SendTCP(string M, string IPA, Int32 PortN) 
{ 
    byte[] SendingBuffer = null; 
    TcpClient client = null; 
    NetworkStream netstream = null; 

    try 
    { 
     client = new TcpClient(IPA, PortN); 
     MessageBox.Show("Connected to the Server...\n"); 

     netstream = client.GetStream(); 
     FileStream Fs = new FileStream(M, FileMode.Open, FileAccess.Read); 
     int NoOfPackets = Convert.ToInt32(Math.Ceiling(Convert.ToDouble(Fs.Length)/Convert.ToDouble(BufferSize))); 

     // progressBar1.Maximum = NoOfPackets; 

     int TotalLength = (int)Fs.Length, CurrentPacketLength, counter = 0; 
     for (int i = 0; i < NoOfPackets; i++) 
     { 
      if (TotalLength > BufferSize) 
      { 
       CurrentPacketLength = BufferSize; 
       TotalLength = TotalLength - CurrentPacketLength; 
      } 
      else 
       CurrentPacketLength = TotalLength; 

      SendingBuffer = new byte[CurrentPacketLength]; 
      Fs.Read(SendingBuffer, 0, CurrentPacketLength); 
      netstream.Write(SendingBuffer, 0, (int)SendingBuffer.Length); 
     } 

     // label1.Text = label1.Text + "Sent " + Fs.Length.ToString() + " bytes to the server"; 
     MessageBox.Show("Sent " + Fs.Length.ToString() + " bytes to the server"); 

     Fs.Close(); 
    } 
    catch (Exception ex) 
    { 
     MessageBox.Show(ex.Message); 
    } 
    finally 
    { 
     netstream.Close(); 
     client.Close(); 
    } 
}

我不知道如何解决这个错误的帮助，请
